Templar Assassin
* All of Jakiro's active skills can be targeted on an area, which is effective at forcing Templar Assassin to move should she 
Meld away.
* Many of Jakiro's spells utilize damage-over-time mechanics, which makes it easy to strip away layers of 
Refraction.
Luna
* Even though Luna can easily kill Jakiro in few strikes, he can also do the same to her is she is not careful.
* 
Dual Breath and 
Liquid Fire allow Jakiro to harass Luna more efficiently than she can harass Jakiro with her 
Lucent Beam.
* Jakiro can save his allies from Luna during her attempts to use 
Eclipse by casting 
Ice Path on Luna.
* 
Aghanim's Scepter upgraded 
Macropyre can deal pure damage-over-time and pierce spell immunity, which can make it very hard for Luna to be in teamfights without suffering too many damage.
* For the same reasons, Jakiro makes a very powerful ally for Luna when they are in the same team.

Templar Assassin
* Sand King can quickly remove her Refraction with his Sand Storm.
* Once Refraction is down, she is very vulnerable to Epicenter's high magic damage.
Luna
* 
Burrowstrike allows Sand King to escape from Eclipse or to close the gap on Luna and finish her off.
* 
Sand Storm allows Sand King to harass Luna more efficiently than she does with Lucent Beam, as it makes him invisible for it's duration and while in it, rendering him safe from both, Lucent Beam and Eclipse and forcing Luna to buy 
Dust of Appearance more often.
* 
Caustic Finale allows Sand King to deal serious damage to both, Luna and her allies, which is especially hazardous in laning stage as Luna's attack range is short.
* 
Epicenter combined with Burrowstrike and Sand Storm can often kill Luna before she can do anything because of her low health and strength gain.
* Overall, Sand King forces Luna to play more defensively instead of offensively, and for the same reasons, Sand King makes a very powerful ally for Luna when they are in the same team.

Templar Assassin
* Dark Pact rips through Refraction charges and still steals attributes during Refraction.
* Pounce and Dark Pact will still hit Templar Assassin while she is Melded. Since she cannot move, both abilities will be easy for Slark to land.
Luna
* 
Shadow Dance prevents Luna from damaging Slark, and together with 
Silver Edge he can easily chase her or escape from her.
* Luna has no way to escape from 
Pounce's leash, which is especially bad as she is not used to buying 
Wind Waker, which is the only way to escape from Pounce outside of 
Black King Bar.
* For the same reasons, Slark makes a very powerful ally for Luna when they are in the same team.
Additional:
* Luna's lack of mobility and escape abilities makes her easily to gank for Slark.
* Shadow Dance helps avoid all the damage from Eclipse.
* For the same reasons, Slark makes a very powerful ally for Luna when they are in the same team.
Luna
* With Dust of Appearance, Luna will be able to use Eclipse on invisible heroes. Be mindful that 
Slark is exception because he'll be able to remove the debuff with 
Dark Pact.
Templar Assassin
* His 
Rot can force Templar Assassin out of her Meld and destroy all of her Refraction charges quickly, and her small health pool and meager defense make her very vulnerable to his 
Meat Hook without Refraction.
Luna
* Even with Black King Bar, Pudge's Meat Hook and 
Dismember can still disable Luna for a fairly long time.
* Many stacks of 
Flesh Heap will make it difficult for Luna to burst down Pudge with Eclipse. 
Aghanim's Shard upgraded Dismember can also allow Pudge to save an allied hero from being killed by Eclipse.
* Bear in mind, however, that Luna can cancel Dismember if some of her allies are targets. Which may force Pudge to buy Black King Bar earlier.
Luna
* Luna can easily cancel channeling spells with Lucent Beam and 0.25s Eclipse Lucent Ministun talent for Eclipse, she can also buy 
Abyssal Blade in case they decide to buy Black King Bar: 
Enigma's 
Black Hole, 
Witch Doctor's 
Death Ward, 
Shadow Shaman's 
Shackles, 
Lion's 
Mana Drain, 
Bane's 
Fiend's Grip, 
Pudge's Dismember, 
Crystal Maiden's 
Freezing Field, 
Pugna's 
Life Drain, 
Dawnbreaker's 
Solar Guardian, and 
Naga Siren's 
Reel In from Aghanim's Scepter.
Templar Assassin
* Phantom Lancer's illusions destroy Refraction charges very quickly.
* 
Diffusal Blade, his core item, drains Templar Assassin's small mana pool, rendering her unable to save herself with Meld.
Additional:
* Phantom Lancer's illusions destroy Refraction charges very quickly.
* Diffusal Blade, his core item, drains Templar Assassin's small mana pool, rendering her unable to save herself with Meld.
Luna
* Even though Luna can clear Phantom Lancer's illusions with Moon Glaives, Phantom Lancer can create too many illusions to tank Luna's Eclipse and for Luna to handle overall.
* 
Doppelganger can be used to dodge a number of Lucent Beams during Eclipse.
* Phantom Lancer can chase Luna effectively regardless of her high movement speed thanks to 
Phantom Rush and 
Spirit Lance.
* Luna's low health pool is easily exploited by the sheer damage output from Phantom Lancer's illusions. Additionally, Phantom Lancer can often create more illusions for Luna to handle.
Luna
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include 
Spectre, 
Shadow Demon, 
Phantom Lancer, Naga Siren, 
Chaos Knight, 
Terrorblade) or bring other units into the fight (such as 
Nature's Prophet, 
Lone Druid, 
Chen, 
Enchantress, 
Meepo and 
Arc Warden).
Templar Assassin
* Weak damage but high tick rate or persist in a long time: Slark, 
Gyrocopter, 
Queen of Pain, Shadow Shaman (Shackles), 
Jakiro, Pugna, 
Doom
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, 
Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, Chaos Knight, Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Luna
* Heroes that can keep Luna locked down for a long time can be a threat (she is very item and spell dependent): 
Faceless Void, 
Legion Commander, Doom.

Luna
* Even though Moon Glaives can bounce between Meepo and his clones, Meepo can tank Eclipse because of his clones.
* 
Earthbind takes away Luna's mobility advantage.
* Meepo can shutdown Luna's split-push ability with his global presence.
Luna

Templar Assassin
* Huskar's burn damage from 
Burning Spear is incredibly strong against Templar Assassin as it completely cancels out her Refraction from the burning over time which results in making her very vulnerable to ganks and harassments, and in turn forcing her out of the lane.
Templar Assassin
* Her Refraction charges can and will be easily burned away by Phoenix's damage over time abilities, and Meld can't protect her from Phoenix's AoE abilities, even without detection.
Additional:
* Phoenix's abilities target and deals damage over time, making them a threat against Meld and Refraction. His abilities' nature makes them pretty hard to correctly land on the target, but that is not a problem against a Templar Assassin that needs to stand still during Meld.
* 
Icarus Dive allows Phoenix to shrug off the slow from her trap and make an easy escape from her ambush.
* As Templar Assassin relies on her quality-over-quantity bursting attacks to make quick work on fragile target, 
Fire Spirits' attack speed reduction can cripple her ability to deals any damage during combat. With the debuff applied in early-mid game, a Meld-breaking hit from her is significantly slowed to the point that her target can travel a safe distance before she even lands the hit.
* 
Sun Ray has a quick damage tick and will burn through her Refraction in no time.
* 
Supernova deals damage over time in an incredibly large area, and again with her quality-over-quantity style, she may not be able to attack quickly enough to break through the Phoenix Sun by herself. (not to mention the debuff from Fire Spirits) This can lead to a failed ganking attempt or even a turnaround.
Templar Assassin
* Ion Shell destroys Refraction's protection stacks in short time.
* Surge ignores the massive slow from 
Psionic Trap.
Templar Assassin
* 
Pulse Nova can easily burn Templar Assassin's Refraction charges quickly, and can also hit her while she is invisible in Meld.
Luna
* Should Luna choose to buy 
Manta Style, Medusa will be able to kill illusions from them with 
Split Shot and 
Mjollnir, which is a common item on Medusa.
* 
Mystic Snake allows Medusa to easily harass Luna and steal mana from her, preventing Luna from retaliating with Lucent Beam.
* Medusa can survive Eclipse thanks to 
Mana Shield, which can cause Luna to struggle greatly in bursting down Medusa and force her to buy Diffusal Blade and it's upgrade 
Disperser.
* Even with Black King Bar, Medusa's 
Stone Gaze will still be able to disable Luna, which could even discourage her from counter-initiating with Eclipse.

* Mystic Snake allows Medusa to easily harass Luna and steal mana from her, preventing Luna from retaliating with Lucent Beam.
* Medusa can survive Eclipse thanks to Mana Shield, and since Luna is not a hero that often goes for Diffusal Blade, she will struggle greatly in bursting down Medusa.
* Even with Black King Bar, Medusa's Stone Gaze will still be able to disable Luna, which could even discourage her from counter-initiating with Eclipse.
* For the same reasons, Medusa makes a very powerful ally for Luna when they are in the same team.
Templar Assassin
* Templar Assassin is dependant on Refraction in teamfights. Because Magnetize deals damage per second and Earth Spirit is even able to refresh the duration of his ultimate he is suitable for wasting Refraction and allowing his team to take her down.
Templar Assassin
* Searing Chains and Flame Guard quickly burn through Refraction instances exposing her low health pool.
* Templar Assassin has no inherent way to prevent Ember Spirit from escaping, a good Ember player also will be able to dodge her meld attack
* Ember Spirit`s 
Searing chains give true sight into invisibility, why Templar Assassin can't hide from it in Meld and get out of the fight using 
Blink Dagger
Additional:
* 
Flame Guard burns quickly through Refraction charges, which is why it can interrupt Templar Assassin, giving his team the opportunity to kill her.
* Ember Spirit can dodge a blow from Meld with 
Sleight of fist, providing him an advantage in a 1v1 situation.
* Searing Chains give true sight into invisibility, why Templar Assassin can't hide from it in Meld and get out of the fight using Blink Dagger.
Templar Assassin
* The damage block instances of Refraction can be burned down with Ignite.
* Fire Shield effectively reduces the burst damage from a Meld-charged ambush from Templar Assassin, provided the spell is cast beforehand.
Templar Assassin
* Despite the armor reduction from Meld, Templar Assassin's reliance on physical damage and medium attack speed is unlikely to harm Dragon Knight.
* Templar Assassin's Refraction charges also get quickly removed by the damage over time from Dragon Knight's ultimate.
Additional:
* The damage over time from Dragon Knight's 
Elder Dragon Form rapidly burns down Refraction, allowing him to attack her.
* Also, 
Breathe Fire reduces Templar Assassin's damage and 
Dragon Tail is a stun with a considerable duration, letting him and his team whittle her health down once her defenses wear off.
* Templar Assassin will struggle to kill Dragon Knight thanks to his high armor and health regen from 
Dragon Blood as she deals entirely physical damage.
Luna
* 
Telekinesis allows Rubick and his team to coordinate a gank on Luna early on. And just like Aghanim's Shard upgraded Dismember, Aghanim's Shard upgraded Telekinesis can also allow Rubick to save an allied hero from being killed by Eclipse.
* 
Fade Bolt allows Rubick to harass Luna on lane and weaken her attack damage early on.
* Both, Lucent Beam and Eclipse are very useful for Rubick to steal with 
Spell Steal, Luna's only way to counter this is with 
Lunar Orbit. Rubick can also use them from further distances than Luna thanks to 
Arcane Supremacy that increases his cast range and when he gets Aghanim's Scepter.
Additional:
* Lucent Beam is a solid magic nuke with a stun.
* Aghanim's Shard upgraded Lucent Beam gives Rubick bonus damage whenever he uses it
* Eclipse can output massive damage if casted by 
Rubick.
* Rubick has a good chance to steal Eclipse since 
Luna has only two cast abilities.
* Aghanim's Scepter greatly increase the effectiveness of the ability, with more damage as well as extended cast range.
* For the same reasons, Rubick also makes a good ally for Luna when they are in the same team.
Templar Assassin
* Sniper destroys Templar Assassin Refraction's only defense with its 
Shrapnel ability, which is why it can easily punch it and kick it off the line, getting more level and gold.
* The huge range of Sniper's attack due to the 
Take Aim ability allows him to spend the whole game at a distance far from Templar Assassin, constantly punching her with his physical attacks, which is why Templar Assassin remains either to run away or hide in Meld, however, even there Sniper will not let her escape with the help of Blink Dagger, since he uses Shrapnel.

Luna
* Heroes that outrange Luna can be a problem for her: 
Drow Ranger, 
Sniper.
Templar Assassin
* Heroes with powerful nuke can waste their precious abilites on her Refraction during a ganking attempt or chaos combat: 
Lich, 
Lina, Sniper, 
Outworld Destroyer 
Zeus
Templar Assassin
* A strong illusion 
Phantasm) from Chaos Knight can cleared from her's Refraction. Additionally, natural items Manta Style can dispell silence Psionic Trap from Aghanim's Shard.
Luna
* Heroes that create illusions: Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Luna
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden).
Templar Assassin
* The three Primal Split brewlings all attacking Templar Assassin at once will remove her Refraction quickly, especially with Fire's Permanent Immolation.
* Templar Assassin has no way to stop Brewmaster from using Primal Split by herself, and may get unlucky and miss her Meld if trying to burst him during her ally's disable.
Templar Assassin
* Attacks from Boars and the attack speed boost from Inner Beast will quickly wear down Refraction.
Templar Assassin
* Batrider's DoT damage quickly removes Templar Assassin's Refraction and can damage her during Meld.
Additional:
* Batrider's abilities are designed to deal damage over time, burning through Templar Assassin's layers extremely quickly. 
Flamebreak applies 7 instances of damage, burning through the entirety of Refraction, and 
Firefly applies damage on the place, forcing her to either get out of Meld and be attacked or stay in place or be incinerated.
* 
Flaming Lasso pierces Black King Bar and rendering Templar Assassin helpless unless there are allies helping her.
Templar Assassin
* Shackles and Mass Serpent Ward instantly destroy Refraction
Luna
* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: 
Sven + Shadow Shaman.
Luna
* Luna's high magical damage burst from Lucent Beam and Eclipse can take advantage of Shadow Shaman's low health and strength gain.
* Without Black King Bar, Luna's Lucent Beam and 0.25 Eclipse Mini-stun talent for Eclipse can be used to disable Shadow Shaman while he is channeling Shackles.
* Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Mini-stun can repetively stun Shadow Shaman, and can even discourage him from even trying to use Shackles.
* Luna is a natural Black King Bar wielder, and almost none of Shadow Shaman's spells can bypass spell immunity, except for 
Mass Serpent Ward.
* Bear in mind, however, that if Shadow Shaman gets a jump on Luna first, he will be able to use 
Hex to disable Luna and burst her down before she can use Black King Bar, Lucent Beam or Eclipse. In addition, 
Moon Glaives cannot bounce on Mass Serpent Wards at all.

Luna
* Every hero that can withstand or prevent Eclipse at level 7: 
Juggernaut, 
Riki, 
Clockwerk, Drow Ranger, 
Abaddon, Faceless Void, 
Weaver, Outworld Destroyer.
Templar Assassin
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: 
Phantom Assassin, 
Nyx Assassin, 
Mirana, 
Bounty Hunter, 
Templar Assassin, Riki, 
Spirit Breaker, 
Anti-Mage, 
Tusk, 
Ursa, Nature's Prophet, Enigma, 
Void Spirit, 
Magnus etc.
Templar Assassin
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: Templar Assassin, Phantom Assassin, 
Ember Spirit, 
Morphling.
Luna
* Heroes that create illusions: Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally.

* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Luna
* Heroes with damage-over-time abilities easily allow Bristleback to turn his back in order to proc 
Bristleback continuously and to massively reduce to damage dealt to him: Arc Warden, 
Venomancer, Luna.
Additional:
* 
Quill Spray and Bristleback harass Luna more efficiently than she does with Lucent Beam.
* Bristleback helps return a lot of damage to Luna’s team if she uses her nukes on him and he has his back to her, and her only way to counter this is by buying Silver Edge.
* 
Viscous Nasal Goo and 
Warpath are enough to outrun a speedy Luna.
* Bristleback tends to be a frequent carrier of 
Crimson Guard and 
Eternal Shroud, which are good protection from Moon Glaives and Eclipse.
* For the same reasons, Bristleback makes a very powerful ally for Luna when they are in the same team.
Templar Assassin
* Heroes with invisibility will be detected by Thirst when they have low enough health: Bounty Hunter, Templar Assassin, Riki, 
Clinkz, Weaver, 
Treant Protector, Nyx Assassin.
Templar Assassin
* Flux removes Refraction charges very quickly, and Arc Warden can hit her freely with his better attack animation, speed and range. If she tries to mute in her creep wave, Spark Wraith can quickly kill the ranged creep, forcing her to stay near the melee creeps, again, allowing for easy right clicks.
* With Tempest Double, Arc Warden can easily output 1000 damage (with the stacking of Flux and Spark Wraith and kill Templar Assassin within seconds. She cannot avoid this combo as Spark Wraith will still hit her in Meld.
* A good Arc Warden can destroy the item timings of a Templar Assassin, and mitigate her impact during the mid-game, when she is the strongest.
* In the late game, if Templar Assassin tries to split push with Aghanim's Scepter, Arc Warden's double can always threaten to kill her if equipped with a 
Bloodthorn and a Blink Dagger , or a 
Hurricane Pike, forcing her to have to use Black King Bar to survive.
* Quick reactions can also protect Arc Warden and his allies from Meld strike with Magnetic Field, and if equipped with a Hurricane Pike, Arc Warden can double force himself away from the attacking Templar Assassin to safety, where after her Black King Bar ends, she can die to Arc Warden's right clicks.
Luna
* Heroes that create illusions: Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Luna
* Luna's Moon Glaives allow her to clear Arc Warden's 
Tempest Double.
* Luna's short range and fast movement speed allow her to fight Arc Warden inside his 
Magnetic Field.
Additional:
* Luna's Moon Glaives allow her to clear Arc Warden's Tempest Double.
* Luna's short range and fast movement speed allow her to fight Arc Warden inside his Magnetic Field.
Luna
* A couple of long-range heroes with excellent laning like Mirana, Lina, 
Necrophos, 
Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.
Templar Assassin
* Heroes who can provide True Sight are always credible threats: 
Slardar, Bounty Hunter, especially Zeus since his 
Lightning Bolt provides True Sight without the need to detect her beforehand to apply the debuff. So even a late-coming Zeus can easily scout a large area to reveal her, and she cannot purge herself from his sight with the dispel talent.
Luna
* Zeus's highly damaging nuke spells with low cooldowns is not something Luna can go against, though Luna can win against Zeus in late game.
* 
Thundergod's Wrath can be used before a fight to harm Luna before she activates Black King Bar, reducing her survivability for that fight.
* For the same reasons, Zeus makes a very powerful ally for Luna when they are in the same team.
Templar Assassin
* Although Lightning Bolt and Thundergod's Wrath can reveal Templar Assassin during Meld, Zeus nonetheless has no way to deal with Refraction.
* Zeus is a rather squishy hero, falling easily to Templar Assassin's high burst damage.
Additional:
* Refraction blocks all of Zeus' damage and Zeus has no innate way of removing the instances quickly.
* Meld helps burst down Zeus' small health pool while he's still working through the Refraction instances.
* 
Psi Blades allow her to harass and zone Zeus in lane.
* Templar Assassin usually buys Blink Dagger, enabling her to quickly close the gap to Zeus' defensive positioning.
Luna
* Escape-type carries: Slark, 
Storm Spirit, Weaver.
Templar Assassin
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom

* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Luna
* Escape-type carries: Slark, Storm Spirit, Weaver.
Templar Assassin
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: 
Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, 
Warlock.
Templar Assassin
* Templar Assassin's Refraction will easily be removed by Eye of the Storm, and Static Link reveals Templar Assassin hiding with Meld and drain the bonus damage from Refraction.
Additional:
* Razor's 
Eye of the Storm damage-over-time easily wear off Refraction charges, allowing Templar Assassin to be damaged.
* 
Static Link empties Templar Assassin's damage output even with the bonus from Refraction, and will keep doing that even if the Razor cannot see her during Meld.
* 
Plasma Field can easily strike her during Meld.
Luna
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, 
Broodmother, Luna, Sniper, 
Troll Warlord, Weaver, Clinkz.
Luna
* Despite Ancient Apparition's fragileness, he can easily harass Luna on lane with 
Chilling Touch due to it's high range and damage. This can get even worse if Ancient Apparition buys Aghanim's Scepter and combines it with items that can give him bonus attack damage and attack speed.
* Chilling Touch combined with 
Ice Vortex can make it difficult for Luna to escape from 
Cold Feet
* 
Ice Blast can nullify any healing Luna receives and any attempt for her to save herself with 
Satanic, even through Black King Bar.
* For the same reasons, Ancient Apparition makes a very powerful ally for Luna when they are in the same team.
Templar Assassin
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: 
Silencer, Crystal Maiden, Warlock, 
Ancient Apparition, 
Grimstroke, Witch Doctor
Templar Assassin
* Venomancer's entire arsenal deals lingering damage over a long time and therefore burns through her Refraction very quickly. Not only that, his persistent slow from 
Poison Sting (it can be re-applied again and again with 
Plague Ward) allows his team to catch up to her even with the disruption from her Psionic Trap.
Additional:
* Venomous Gale and Plague Wards allow to quickly melt through Refraction charges.
* Both Poison Nova and Venomous Gale hit invisible units, so Meld cannot be used defensively.
Templar Assassin
* Slardar can attack through Plague Wards and gain 
Bash of the Deep charges, and Templar Assassin can spill Psi Blades through Plague Wards too.
Luna
* 
Demonic Purge takes off Luna's superior mobility, removing the need for chasing her and allowing your team to reposition in team fights or escape when at low HP. If Shadow Demon has Aghanim's Scepter it will also take away glaive bounces and extra damage from Luna's passive. And Luna's commonly items Manta Style and Black King Bar does not work dispell to Demonic Purge
* Luna's illusions created by Disruption are very valuable with their Moon Glaives. These will effectively counter her pushing attempts and are painfully effective in team fights.
* Disruption can be used to save an ally from Eclipse.
* For the same reasons, Shadow Demon makes a very powerful ally for Luna when they are in the same team.
Additional:
* Demonic Purge takes off Luna's superior mobility, removing the need for chasing her and allowing your team to reposition in team fights or escape when at low HP. If Shadow Demon has Aghanim's Sceptre it will also take away glaive bounces and extra damage from Luna's passive.

Luna
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden).
Templar Assassin
* 
Bushwhack can tear through Refraction as it does multiple intervals of damage.
Luna
* Moon Glaives can ignore certain abilities that either trigger on attack or give evasion under the condition that the heroes who have them are not primary targets. Examples include: 
Centaur Warrunner, 
Windranger, Phantom Assassin, 
Hoodwink etc.
Templar Assassin
* 
Focus Fire tears apart Templar Assassin's Refraction very quickly and easily bursts her down due to her low health pool against Windranger's immense attack speed.
* Templar Assassin's Psionic Trap doesn't slow down Windranger due to 
Windrun. Additionally, Windranger can survive Templar Assassin's high burst damage thanks to the evasion it provides.

Templar Assassin
* Swashbuckle quickly burns away Refraction charges.
* Lucky Shot can possibly disrupt Templar Assassin when she is boosted with Refraction.
* Pangolier's abilities which does not need to target and has big area of effect allows him to damage her even during Meld.
* Pangolier's high mobility easily shrug off the slow from Psionic Trap.
Templar Assassin
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, Templar Assassin, Arc Warden
Templar Assassin
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, Warlock.
Luna
* All assassin-type carries in a one against one situation: Meepo, Phantom Assassin, Riki, Ursa. Luna's only chances are that she buys 
Ethereal Blade or Black King Bar to gain a slight edge against them, or both items if necessary.
Luna
* Luna can push very fast with Moon Glaives, which is something Riki cannot deal with well.
* Luna is naturally very fast, making it hard for Riki to trap her in Smoke Cloud.
* Even though Riki can evade Eclipse with his invisibility, smart Luna will always buy Dust of Appearance, providing vision on Riki to her allies and herself.

Templar Assassin
* Shadow Fiend's fragility and lack of a natural escape mechanism makes him a great target for Templar Assassin's Meld.
* Shadow Fiend's burst damage, such as 
Shadowraze and 
Requiem of Souls, is easily nullified by her Refraction.
Luna
* Lucent Beam and Eclipse with ministun talent can be used to cancel Requiem of Souls if Shadow Fiend does not have Black King Bar. Likewise, since Shadow Fiend is prone to buying Blink Dagger, an ill-timed Blink Dagger can give Luna a free chance to counter-initiate with Eclipse.
* Moon Glaives and 
Lunar Blessing allow Luna to outfarm Shadow Fiend in lane and the high physical damage output they provide her can also help her deal with Shadow Fiend even when he buys Black King Bar in late game.
* A well timed Eclipse will burst and kill Shadow Fiend before he even either initiates or gets a chance to retaliate, especially when equipped with Aghanim's Scepter and Ethereal Blade, this could become even worse for Shadow Fiend if he does not have Black King Bar. But bear in mind however, that smart and skilled Shadow Fiend can buy Wind Waker to counter this issue.
* Even though Shadow Fiend can evade all of Luna's abilities with 
Shadow Blade, smart Luna will always buy Dust of Appearance to provide vision on Shadow Fiend to her and her team.

Templar Assassin
* Centaur has nothing to deal with Refraction that will negate all of his burst damage.
* Psionic Traps provide good vision, making for him harder to initiate.
Luna
* Luna's Moon Glaives will not trigger 
Retaliate if they hit some other target first. Also Luna commonly buys items that provide lifesteal such as Satanic, which lets her heal from the damage of Retaliate, meaning that Retaliate has little effect against her.
* Eclipse can be used to counter-initiate against Centaur Warrunner after he jumps in with Blink Dagger, and initiates with 
Hoof Stomp. But remember that Centaur Warrunner can resolve this problem by buying 
Hood of Defiance and it's upgrade 
Pipe of Insight to diminish its damage. Or 
Blade Mail to reflect the damage of the Eclipse back at Luna.
* Luna also commonly buys Black King Bar, which will allow her to protect herself from both, Centaur Warrunner's abilities (except for the Retaliate), and damage reflect from Blade Mail.

Templar Assassin
* Refraction protects against Anti-Mage's low burst damage, and allows her to win most fights against Anti-Mage during the early game.
* Meld's burst damage and armor reduction is often enough to finish off Anti-Mage before he Blinks away.
Luna
* Although Anti-Mage can survive Luna's magical damage output with 
Counterspell, Luna's physical damage from Moon Glaives and Lunar Blessing can be fair enough to deal with him.
* Reckless use of 
Blink will allow Luna Eclipse can finish off Anti-Mage from early-to-mid stages of the game until Anti-Mage gets Manta Style, Aghanim's Scepter that will give him access to 
Blink Fragment and Aghanim's Shard which will allow Counterspell to weaken enemy spell damage.
* However, Luna needs to finish the match as quickly as possible, because Anti-Mage is a hero who has a big advantage in longer matches once he farms items he needs for teamfights.
Templar Assassin
* Her Psionic Traps will usually disable Earthshaker's Blink Dagger prior to a teamfight, preventing him from initiating.
* Refraction blocks all of Earthshaker's abilities.
Luna
* Luna's Lucent Beams and Eclipse will prevent Earthshaker from initiating or re-initiating.
* Aghanim's Scepter upgraded Eclipse can be used to counter-initiate against Earthshaker after he uses Aghanim's Scepter upgraded 
Enchant Totem.
* Skilled Luna can buy either {I|Gleipnir

* Templar Assassin Meld`s ability will break Timbersaw's armor, which makes it very easy to break through and not feel his 
Reactive Armor, which will allow the team to kill Timbersaw quickly, or drive him out of the fight.
* Templar Assassin's Refraction ability gives her the ability to avoid damage from 
Whirling Death, which will give her the ability to deal Timbersaw more damage than he will deal.

Monkey King, 
Alchemist, 
Timbersaw.
Templar Assassin
* Heroes who can delivers a big chunk of damage in few hits will find themselves struggle against Templar Assassin's Refraction: Sven, Phantom Assassin, Ursa, 
Wraith King, 
Lifestealer
Luna
* Although Lifestealer can avoid Eclipse with 
Rage and 
Infest, Luna's physical damage can be enough to deal with him.
* Manta Style is a common pick on Luna, which can help her dispel slows from 
Ghoul Frenzy and 
Open Wounds. In addition, Lifestealer is not good against illusions created by Manta Style.

* Even though Wraith King can easily get a chance to retaliate with 
Reincarnation after Luna uses Eclipse against him, smart Luna can also turn Reincarnation against him by using Eclipse right after Reincarnation triggers and gets on cooldown, giving Luna an element of surprise she can use against Wraith King.
* Moon Glaives can be used to clear the waves of Wraith King's skeleton warriors summoned from 
Vampiric Spirit.

Luna
* Even though Phantom Assassin can easily kill Luna in few strikes, Luna can also do the same to Phantom Assassin if she is not careful.
* An ill-timed and ill-positioned 
Phantom Strike will make Phantom Assassin an easy target for counter-attack with Eclipse if she does not have Black King Bar available to use and if Phantom Assassin cannot kill Luna fast enough. This can be even better if Luna buys Aghanim's Scepter.
* Moon Glaives can ignore 
Blur's evasion if Luna attacks an enemy near Phantom Assassin.
* Luna can counter Blur's evasion by buying either Silver Edge, or 
Monkey King Bar, which are common items on Luna.
* Luna just has to be careful about 
Fan of Knives from Aghanim's Shard and 
Coup De Grace, as Fan of Knives can disable Moon Glaives and Lunar Blessing while Coup De Grace can deal serious damage to her even if she is spell immune, though this issue can be solved by buying Ethereal Blade, which is a situational item on Luna.

Templar Assassin
* Refraction can be very useful in safely neutralizing Proximity Mine fields, or absorbing Techies' Blast Off combo.
Luna
* Lucent Beam can be used to harass Muerta in lane.
* Luna's high movement speed can make it difficult for Muerta to hit her with 
Dead Shot and keep her trapped in 
The Calling.
* 
Pierce the Veil will not save Muerta from Luna at all. Instead, it will sentence her to death as it will amplify the magical damage from both, Lucent Beam and Eclipse, potentially turning Muerta's most powerful ability against her. Aghanim's Scepter upgraded Eclipse can also be used to counter-initiate against Muerta.
* Luna can use Aghanim's Shard upgraded Moon Glaives to reduce all the damage Muerta inflicts on Luna while also damaging Muerta if she is too close to Luna. Bear in mind, however, Aghanim's Shard upgraded Moon Glaives cannot damage Muerta while she is under effects of Pierce the Veil.
* As Luna naturally buys Black King Bar, she will be able to defend herself from Muerta's abilities. Luna can also buy 
Revenant's Brooch to attack Muerta even through Pierce the Veil.
* Overall, most of the attempts for Muerta to gank and kill Luna will hurt Muerta more than Luna.

Templar Assassin
* Refraction negates all of Void Spirit's burst damage.
* Meld quickly burns through 
Resonant Pulse.

Luna
* Luna's Moon Glaives and Lunar Blessing can help her destroy Tombstone easily, and this becomes more effective if Luna is equipped with Manta Style.
* Spell Immunity of Zombies from Tombstone is a total disadvantage against Luna because Eclipse will strike only Undying, which can turn Undying's own ability against him.
* Though Undying often builds Blade Mail which can turn Luna's burst damage against her, Luna often builds Black King Bar which will allow her to attack Undying freely because Blade Mail cannot pierce spell immunity.

* Though Bane's 
Enfeeble can weaken Luna's physical damage output, it still does not weaken her magical damage output, although it will still reduce her cast range.
* Without Black King Bar, Luna's Lucent Beam and 0.25 Eclipse Mini-stun talent for Eclipse can be used to disable Bane while he is channeling Fiend's Grip.

* Even though Nyx Assassin can easily kill Luna with his high burst damage, Luna can also do the same to him if he is not careful.
* Lucent Beam can deal a fair amount of damage to Nyx Assassin if he has no 
Spiked Carapace available to use. Although Luna should be patient using Lucent Beam on Nyx Assassin when he uses Spiked Carapace.
* As Luna commonly buys Black King Bar, she can use it to freely attack Nyx Assassin whenever he tries to defend himself with Spiked Carapace during teamfights. Luna can also buy 
Eye of Skadi and Manta Style to survive Nyx Assassin's burst damage and distract him.
* Though 
Vendetta can deal serious damage to Luna and avoid Eclipse, smart Luna will always buy Dust of Appearance to provide vision on Nyx Assassin to her and her team.

Templar Assassin
* Templar Assassin can easily counter Invoker's last hitting process in the early game with Refraction. Refraction also negates the stun from Cold Snap, since it will need to deal damage in order to apply its stun.
* Additionally, Refraction completely blocks damage from Sun Strike should Invoker try to finish her off, provided she activate Refraction beforehand.
Luna
* Lucent Beam can be used to cancel both, Tether and Relocate.
* Like with Leshrac's 
Diabolic Edict, 
Lightning Storm and Pulse Nova abilities. Luna's Moon Glaives and Eclipse abilities can make short work of Io and its tethered ally, particularly when upgraded with Aghanim's Scepter.

* Even though Luna has a hard time laning against Tinker because of 
Heat-Seeking Missile and 
Laser, she can win against him in late game once she buys Black King Bar, as none of Tinker's spells can bypass spell immunity.
* Lucent Beam and 0.25 Eclipse Lucent Mini-stun talent for Eclipse can be used to cancel 
Rearm and prevent Tinker's escape attempts with 
Boots of Travel. Luna can also use Lucent Beam and Eclipse if she is blinded with Laser.

* However, Luna needs to approach Tinker carefully, as Tinker is a natural 
Scythe of Vyse wielder, and if he gets a jump on Luna first, he will be able to use it to disable and burst down Luna before she can use Black King Bar, Lucent Beam or Eclipse.

* Moon Glaives is very effective against Visage because not only it can easily destroy Visage's Familiars, but can also remove one instance of Gravekeeper's Cloak upon each hit to Visage, leaving him susceptible to damage.
* Once Visage's Familiars are picked off and all instances of Gravekeeper's Cloak are removed, Luna will be able to easily kill Visage with Eclipse.

* Templar Assassin has a hard time maneuvering around Pit of Malice.
* 
Atrophy Aura weakens Templar Assassin's damage output, as she relies on direct attacks to be effective.
* However, Templar Assassin's Psionic Traps can be used to intercept Underlord and his team, and to keep her team alerted on Underlord if he chooses to use 
Fiend's Gate to get to a designated point of the map.
Templar Assassin
* Heroes that provide vision will see Fiend's Gate coming: 
Techies, Templar Assassin, Treant Protector.
Luna
* Lunar Blessing gives allies bonus damage and armor required to endure against Atrophy Aura early on.
* Eclipse can be devastating for Underlord's team when they're grouped up for Fiend's Gate, it can also be used to intercept arrivals with Fiend's Gate. And Pit of Malice does not prevent Luna to use it.
* To make things even better, Aghanim's Scepter upgraded Eclipse can finish off Underlord or any of his teammates escape attempts with Fiend's Gate if timed correctly.

Templar Assassin
* As with other heroes mentioned in this section, Templar Assassin is not a hero that is fully "countered" by Crystal Maiden (the way she is against 
Viper and Jakiro), however, the proper combination and execution Crystal Maiden's spells, stacked with her team, can most certainly spell the end for Templar Assassin. Though as the later the game goes, and fighting her without team is not the best choice.
* Frostbite can quickly eat away Refraction charges, leaving Templar Assassin vulnerable for the rest of her team to kill.
* Freezing Field will still apply damage to Templar Assassin when she is under the effect of Meld, making it an even less viable form of escape until a Blink Dagger is purchased.
* Blink Dagger is also cancelled by all of Crystal Maiden's spells, and the fairly short cooldowns on Frostbite and Crystal Nova make her a great asset to a chase against Templar Assassin.
* This is not to say that Templar Assassin has any difficulty killing off the low armor, low HP pool Crystal Maiden, so fighting her alone is never advised.
Templar Assassin
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, Ancient Apparition, Grimstroke, Witch Doctor
Luna
* Lucent Beam allows Luna to easily cancel Freezing Field.
* Without Black King Bar protection, Lucent Beam and Eclipse can make a short work out of Crystal Maiden's abysmal health.
* Skilled Luna will always buy Dust of Appearance, allowing her team to have a vision on Crystal Maiden while invisible and during channeling Freezing Field.
* Even with Black King Bar, Luna can still inflict considerable damage on Crystal Maiden with her attacks, which get empowered with Moon Glaives and Lunar Blessing, also smart and skilled Luna will buy Abyssal Blade to cancel Freezing Field even through Black King Bar in case of emergency. And since Crystal Maiden rarely buys Linken's Sphere, this can be a very big problem for her.

* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, Chaos Knight, Naga Siren (bonus for her Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Templar Assassin

* Luna can easily cancel channeling spells with Lucent Beam and 0.25s Eclipse Lucent Ministun talent for Eclipse, she can also buy Abyssal Blade in case they decide to buy Black King Bar: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.
Luna
* Heroes who are melee but cannot fight back against Eclipse will really struggle with Luna: Monkey King, Alchemist, Timbersaw.
Templar Assassin
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz

Templar Assassin
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, Ancient Apparition, Grimstroke, Witch Doctor
Templar Assassin
* Because Oracle uses few, powerful instances of damage to kill enemies, Templar Assassin's Refraction and 
Visage's 
Gravekeeper's Cloak can absorb his burst damage.
Luna
* Heroes that create illusions: Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Luna
* Luna's Moon Glaives combined with Lunar Blessing can easily kill Chen's creeps.
* Eclipse can be used after Luna clears all of Chen's creeps to easily kill Chen or any of his allies before he can save them with 
Hand of God. This can get even worse if Luna buys Aghanim's Scepter. And Chen is not a hero that likes to buy Black King Bar to counter this problem.

However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Luna
* Enchantress has pitiful HP, even more pitiful than Luna, so Lucent Beam and Eclipse will often harass and/or kill her through her Untouchable.
* With Moon Glaives, Luna can clear Enchantress's creep wave efficiently.
Additional:
* Though Enchantress's 
Untouchable can greatly reduce Luna's attack speed, and can go through any form of Spell Immunity, she has a pitiful HP so Lucent Beam and Eclipse can kill her very quickly.
* Moon Glaives allows Luna to clear Enchantress's creeps very efficiently.
Luna
* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: Sven + Shadow Shaman.
Templar Assassin
* Sven has no easy way to burn Refraction charges and needs help from teammates to kill TA successfully.

Luna
* Moon Glaives and Lunar Blessing help Luna quickly kill Nature's Prophet's treants.
* Luna can easily cancel Teleportation with her Lucent Beam.
* Even though Nature's Prophet can evade all of Luna's abilities with Shadow Blade, a smart Luna will always buy Dust of Appearance to provide vision on Shadow Fiend to her and her team.
Additional:
* Moon Glaives and Lunar Blessing help Luna quickly kill Nature's Prophet's treants. Aghanim's Shard upgraded Moon Glaives can also reduce damage Nature's Prophet will inflict on Luna while they are active.
* Luna can easily cancel Teleportation with her Lucent Beam.
* Even though Nature's Prophet can evade all of Luna's abilities with Shadow Blade, a smart Luna will always buy Dust of Appearance to provide vision on Nature's Prophet to her and her team.
Templar Assassin
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, Chaos Knight, Naga Siren (bonus for her Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Luna
* Aggressively blinking is not going to end well against Luna, because Queen of Pain will be an easy target for Lucent Beam & Eclipse.
* Queen of Pain's HP is abysmal, so Luna can quickly kill Queen of Pain as soon as she initiates with Blink.
Additional:

Luna
* A couple of long-range heroes with excellent laning like Mirana, Lina, Necrophos, Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.
Luna
* Even though Luna has a hard time laning against Necrophos, his 
Ghost Shroud won’t protect him in teamfights because it will increase the damage from Lucent Beam and Eclipse.
* Luna is a natural Black King Bar wielder, and none of Necrophos's spells can bypass spell immunity outside of 
Heartstopper Aura.

Templar Assassin
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, Warlock.
Luna
* If Luna chooses to use Eclipse in anticipation right before Spirit Breaker gets to her with Charge of Darkness, she will be able to kill Spirit Breaker before he will be able to kill her as Spirit Breaker's attack speed is rather low.
* Meanwhile, when Spirit Breaker is focusing on any of Luna's allies with Charge of Darkness, Aghanim's Scepter upgraded Eclipse can be used to counter-initate against Spirit Breaker.
* Aghanim's Shard upgraded Moon Glaives allows Luna to reduce damage from Greater Bash and Nether Strike inflicts on her, and damage Spirit Breaker whenever he is close to her, even while he is invisible.
* Lucent Beam can be used to cancel Spirit Breaker's Charge of Darkness under the condition that Luna is able to cast it on time. Lucent Beam can also be used to cancel Nether Strike. But bear in mind, however, that Spirit Breaker can counter this with 
Planar Pocket from Aghanim's Shard which can be used to reflect Lucent Beam back at Luna.
* If Luna buys Linken's Sphere, it will become nearly impossible for Spirit Breaker to reach Luna unless some of Spirit Breaker's allies can pop it and put it on a cooldown.
* Even though Spirit Breaker can evade all of Luna's abilities with Shadow Blade, smart Luna will always buy Dust of Appearance to provide vision on Spirit Breaker to her and her team. Luna can also buy 
Gleipnir to counter Spirit Breaker's Charge of Darkness and Shadow Blade combo.

Luna
* Without Black King Bar, Luna will be able to cancel Enigma's Black Hole from safe distance with her Lucent Beam or with 0.25s Eclipse Lucent Ministun talent for Eclipse and counter-initiate with Eclipse. This can get even worse for Enigma once Luna gets Aghanim's Scepter and combines it with 0.25s Eclipse Lucent Ministun talent that will allow Luna to use Eclipse from safe distance.
* If Luna chooses to use Eclipse in anticipation right after Enigma jumps in with Blink Dagger, she will be able to kill Enigma before he even gets a chance to use Black Hole. Aghanim's Scepter upgraded Eclipse can be used to counter-initiate against Enigma from safe distance if he has no Black King Bar available to use.
* Luna commonly buys Satanic, which can help her recover from Enigma's Black Hole in case she survives it.
* Moon Glaives combined with Lunar Blessing can make a short work of Enigma's Eidolons before Luna uses Eclipse. Aghanim's Shard upgraded Moon Glaives can be used to reduce damage Luna will take from Enigma's Eidolons and Black Hole if used in anticipation while also clearing waves of Enigma's Eidolons and damaging Enigma if he is too close to Luna.
* Bear in mind, however, that once Enigma gets Black King Bar, Luna will be out of solutions to cancel Black Hole, and going for Abyssal Blade on Luna can be risky due to Abyssal Blade's very short cast range.

Templar Assassin
* Heroes that have disposable area-targeted spells can force her to undo her Meld: 
Leshrac, 
Puck, 
Tiny, Jakiro,. An experienced Templar Assassin could try to use Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Templar Assassin
* None of Puck's abilities have any damage-over-time components, meaning that Refraction is a valuable form of defense against Puck's lane harassment.
* Psi Blades deals pure damage and spills over instantly. Puck cannot reliably dodge the damage with Phase Shift.
Additional:
* Puck high magical burst is almost completely useless against Refraction. Templar Assassin often buys 
Orchid Malevolence to render Puck useless in teamfights.
Luna
* Heroes that can keep Luna locked down for a long time can be a threat (she is very item and spell dependent): Faceless Void, Legion Commander, Doom.
Luna
* A well-timed Eclipse before a Duel usually prevents Legion Commander from winning Duels, if Luna is the target.
* Meanwhile, when Luna is not a target, Eclipse and Lucent Beam can also help an ally win a Duel against Legion Commander.
* However, skilled Legion Commander will always buy a Black King Bar to block Eclipse and Lucent Beam or Aghanim's Scepter to reduce it's damage.

Luna
* Even though Luna is the kind of hero that Mirana can handle due to 
Moonlight Shadow rendering her safe from Eclipse with Moonlight Shadow, smart Luna can buy Dust of Appearance, allowing her to provide vision on her to her team, and possibly, kill Mirana.
* Luna's high movement speed allows her to evade 
Sacred Arrow, giving Mirana difficulties in hitting her with it.
* Aghanim's Scepter upgraded Eclipse combined with Dust of Appearance allows Luna to cast it on a hero that is struck by Sacred Arrow and/or after Mirana jumps in with 
Leap.

Luna
* Heroes that rely on base damage: Luna, Phantom Lancer are easily countered with Anchor Smash.
Luna
* Luna often builds Black King Bar, and none of Tidehunter's spells can bypass spell immunity.
* Though 
Anchor Smash can weaken Luna's physical damage, it does not weaken her magical damage, which means that Lucent Beam and Eclipse deal a lot of magic damage in the early and mid-game, which can bypass Tidehunter's 
Kraken Shell.
Additional:

Luna
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Destroyer.
Templar Assassin
* Refraction blocks most of the damage dealt with Arcane Orb and Sanity's Eclipse if used correctly, and is difficult for Outworld Destroyer to deal with.
* If Astral Imprisonment is on cooldown, then an Outworld Destroyer slowed by Psionic Trap is an easy kill for Templar Assassin, especially during the laning stage.
Templar Assassin
* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin can have their damage mitigated by Cold Embrace.
Luna
* Cold Embrace is no salvation against Lucent Beam and Eclipse.
* Moon Glaives will not hit a hero affected by Winter's Curse, making it weak against allies, but strong versus enemies.
* Luna has better night vision provided by Lunar Blessing than Winter Wyvern when affected by Arctic Burn.

Luna
* Lina has very high magic burst damage to use against the low-health-pool Luna. 
Laguna Blade can also be upgraded with Laguna Blade damage is Pure and pierces Spell Immunity to bypass Black King Bar, making Lina even more of a threat. Luna however, can easily counter this problem with Linken's Sphere, which is a common item for her.
* For the same reasons, Lina makes a very powerful ally for Luna when they are in the same team.
Templar Assassin
* Templar Assassin can outmatch Lina on the center line thanks to her own Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her.
* Refraction is good defense against Lina's burst damage. But remember that Lina can partially counter this with 
Dragon Slave's damage over time.
Additional:
* Outlanes Lina on the center line thanks to her own Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her
* Closes from Lina's magic attacks with her own Refraction, which is why Lina can't make her combination: 
Light Strike Array, Dragon Slave, Laguna Blade and kill Templar Assassin quickly
Templar Assassin
* Ensnare disables Templar Assassin's invisibility and Blink Dagger (a core item on Templar Assassin), and her illusions will break Refraction easily.
Luna
* Heroes that create illusions: Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Templar Assassin
* Heroes whose attacks can affect multiple enemies at once will clear Naga Siren's illusions. Such heroes include Sven, Magnus, 
Dragon Knight, Luna, 
Medusa, Templar Assassin, Gyrocopter, 
Muerta.
Luna
* Luna's Moon Glaives and Lunar Blessing can clear waves of Naga Siren's illusions from 
Mirror Image.
* Once Naga Siren's illusions are cleared with Aghanim's Shard upgraded Moon Glaives, Eclipse can often finish off Naga Siren before she can escape with 
Song of the Siren.
* A well-timed Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Lucent Ministun talent can be casted at long range and allow Luna to burst down Naga Siren faster and repetively stun Naga Siren, preventing her from escaping with Song of the Siren and 
Town Portal Scroll without getting caught in it's range.
* Luna is a natural Black King Bar wielder unlike Naga Siren who barely goes for it, which allows Luna to freely attack Naga Siren during Song of the Siren and potentially get rid of the most of the damage and crowd-control from Naga Siren.
Additional:
* Luna's Moon Glaives and Lunar Blessing can clear waves of Naga Siren's illusions from Mirror Image, especially when combined with Gleipnir and Manta Style. Aghanim's Shard upgraded Moon Glaives can also be used to destroy Naga Siren's illusions and damage the real Naga Siren if they are too close to Luna while also reducing any damage Naga Siren inflicts on Luna for their duration.
* Once Naga Siren's illusions are cleared, Eclipse can often finish off Naga Siren before she can escape with Song of the Siren.
* A well-timed Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Lucent Ministun talent can be casted at long range and allow Luna to burst down Naga Siren faster and repetively stun Naga Siren, preventing her from escaping with Song of the Siren and Town Portal Scroll without getting caught in it's range.

Templar Assassin
* Heroes that have disposable area-targeted spells can force her to undo her Meld: Leshrac, Puck, Tiny, Jakiro,. An experienced Templar Assassin could try to use Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Templar Assassin
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Templar Assassin
* The damage over time from Viper's 
Poison Attack and 
Viper Strike rapidly wear down Refraction charges, allowing Templar Assassin to be damaged. Additionally, 
Corrosive Skin causes her attacks to apply damage overtime on her as well.
* 
Nethertoxin is a big threat to Templar Assassin. Her initially low range making it very hard to deal against Nethertoxin in the laning phase. At any stage of the game, a Nethertoxin can always force her to undo her Meld.
Additional:
* All of Viper's abilities quickly burn through Refraction charges.
* Templar Assassin's short range, aside from Psi Blades' spill damage, makes her vulnerable to Poison Attack harassment.
* Templar Assassin usually buys health and armor items for damage. Outside of Black King Bar, Viper will almost always be able to kill her when Refraction is down.
Luna
* Even though Luna has a hard time laning against Viper due to Nethertoxin being able to disable Moon Glaives and Lunar Blessing, Luna can take out Viper once she builds either Black King Bar or Silver Edge which will allow her to attack Viper freely.
* Eclipse can often finish off Viper from early-to-mid stages of the game before he can retaliate as Corrosive Skin gives little magic resistance to him early on.
* Manta Style is an item that Luna commonly buys in most of the games, which lets her disjoint Viper Strike. Additionally, illusions from Manta Style can make Viper waste time attacking them.

Luna
* Hard-hitters who relies mostly on raw stats or good passive and therefore make a perfect target for 
Dark Portrait: Naga Siren, Faceless Void, Terrorblade, Luna, Anti-Mage
Templar Assassin
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, Ancient Apparition, Grimstroke, Witch Doctor
Templar Assassin
* Terrorblade's high armor makes him exceptionally tanky against physical attacks, and Templar Assassin's main damage source is mostly physical damage, it would be difficult for her to take down Terrorblade quickly even with Meld and Refraction.
* Terrorblade's illusions combo with Manta Style and 
Reflection can make a short work to burn Refraction instances, and combined with Eye of Skadi, Terrorblade can chase down Templar Assassin easily.
* 
Sunder is not blocked by Refraction's damage block.
Luna
* Heroes that create illusions: Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Templar Assassin
* Heroes whose attacks allow them to deal either magical or pure damage that can bypass Terrorblade's high armor: Faceless Void, Silencer, Spirit Breaker, Spectre, Templar Assassin, Outworld Destroyer.
Luna
* If carefully timed, Aghanim's Scepter upgraded Eclipse combined with 0.2s Eclipse Lucent Ministun talent can quickly finish off Terrorblade before he can get a chance to save himself with Sunder due to its high magical damage as long as Terrorblade has no Black King Bar.
* Moon Glaives allows Luna to clear Terrorblade's illusions from both, Conjure Image and Manta Style, this can be particularly advantegous for Luna if she has Manta Style. Just bear in mind, however, that Reflection can be used to turn Moon Glaives against Luna during laning phase.
* Luna very often builds Satanic and Black King Bar, which allows it either to protect herself from Sunder or nullify it's effects.
* Luna can also buy Monkey King Bar to help her deal with Terrorblade's high armor, which is a common item on Luna.

Aghanim's Shard upgraded Moon Glaives can be used to reduce damage Luna will take from Terrorblade and his illusions while also clearing waves of them and damaging Terrorblade if he is too close to Luna.
* Luna very often bulds Satanic and Black King Bar as well as it's alternative item Linken's Sphere, which allows her either to protect herself from Sunder or nullify it's effects.
* Luna can also buy Monkey King Bar to help her deal with Terrorblade's high armor, which is a common item on Luna. Likewise Luna can also buy Revenant's Brooch or Gleipnir whose attacks can also ignore Terrorblade's high armor.
Luna
* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, Luna, Sniper, Terrorblade.
Luna
* Luna's Eclipse can be used for counter-attacks and interception against gap-closing heroes who use their blinking abilities without protection or who recklessly jump on her, provided that Luna is able to cast it in time. Examples include: Queen of Pain, Riki, Phantom Assassin, Faceless Void and pretty much any hero who relies on Blink Dagger to close the gap.
Templar Assassin
* Pugna's 
Decrepify can render Templar Assassin's physical attacks useless.
* Pugna can also cast Life Drain on Templar Assassin, burning her Refraction instances.
* On the other hand, Pugna generally has low health and armor. Use this to your advantage.
Luna
* Luna can deal constant damage to Pugna through the low-cooldown Lucent Beam and her right clicks.
* Life Drain will be always canceled by Lucent Beam if Pugna does not have Black King Bar.
* Decrepify can be suicide against Luna due to Lucent Beam and Eclipse.
* 
Nether Ward is rather weak against Luna because unlike other heroes who rely on magical damage to damage or kill enemies, yet their ablities have very high mana costs, Luna does not have abilities that cost a lot of mana and Luna mostly uses her abilities to initiate a teamfight or to finish off fleeing enemy heroes.
* Luna is a common Black King Bar carrier, which allows her to protect herself against Pugna's only-magical damage output.

However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Luna
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden).
Templar Assassin
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, Warlock.
Additional:
* Warlock can cast Upheaval when Templar Assassin uses Meld, preventing her from escaping at the right moment.
* Warlock can also send his Warlock Golem near where she used Meld, preventing escape by Blink Dagger due to the Warlock Golem's 
Permanent Immolation.
* Warlock's Golem's Permanent Immolation will burn away Refraction with its damage over time.
Templar Assassin
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, Ancient Apparition, Grimstroke, Witch Doctor
Templar Assassin
* Heroes who can provide True Sight are always credible threats: Slardar, Bounty Hunter, especially Zeus since his Lightning Bolt provides True Sight without the need to detect her beforehand to apply the debuff. So even a late-coming Zeus can easily scout a large area to reveal her, and she cannot purge herself from his sight with the dispel talent.
Luna
* Illusion heroes like the aforementioned Phantom Lancer or Naga Siren, or heroes that tend to buy Manta Style, like Luna or Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
Luna
* All assassin-type carries in a one against one situation: Meepo, Phantom Assassin, Riki, Ursa. Luna's only chances are that she buys Ethereal Blade or Black King Bar to gain a slight edge against them, or both items if necessary.
Templar Assassin
* Heroes who can delivers a big chunk of damage in few hits will find themselves struggle against Templar Assassin's Refraction: Sven, Phantom Assassin, Ursa, Wraith King, Lifestealer
Additional:
* Templar Assassin usually places Psionic Traps inside the Roshan Pit (and can teleport herself to the traps with an Aghanim's Scepter), preventing Ursa from killing Roshan without getting noticed by the enemy team.
Luna
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Destroyer.
