Templar Assassin
* Refraction for Templar Asassin can't protect against Chaos Knight typical burst damage with 
Chaos Strike combinated 
Chaos Bolt stunned and illusions 
Phantasm and 
Manta Style.
* Either illusions for Chaos Knight Phantasm or Manta Style can dispells after Psionic Trap activated slow movement speed or Trap silence upgrade 
Aghanim's Shard.
* Chaos Knight items 
Assault Cuirass and abilities 
Reality Rift can easily reduced armor for Templar Asassin's.
Lifestealer
* Level 20 talent allows Reality Rift to bypass spell immunity provided by 
Rage, thus negating the advantage Lifestealer has in his kit.
* The fact that Lifestealer lacks wave clearing and reliable lockdown makes it difficult to fight Chaos Knight's illusions.
* 
Feast is largely negated by Chaos Knight's high burst damage from Chaos Strike.
Additional:
* Chaos Strike is a strong burst damage passive that allows Chaos Knight to stand up and even survive Lifestealer's attacks. Level 20 Talent: Reality Rift Pierces Spell Immunity allows him to burst down Lifestealer even while he is in Rage.
* Lifestealer's single-target nature will struggle against Chaos Knight's Phantasm illusions and will be forced to itemize for them.
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.
Lifestealer
* 
Shadow Dance allows Slark to attack Lifestealer for its duration without any way for Lifestealer to fight back, allowing him to steal his stats with 
Essence Shift, which also reduces Lifestealer's strength and, therefore, health pool.
* Slark can easily escape Lifestealer with 
Pounce, and can avoid Open Wounds with 
Dark Pact should Lifestealer be forced to itemize for it.
* Slark commonly buys a 
Silver Edge, which can break Lifestealer's Feast, severely diminishing his damage output and lifesteal.
Templar Assassin
* Windranger's 
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 her skill 
Windrun.
* Templar Assassin's high damage can also be easily evaded thanks to Windrun's 100% evasion.
Lifestealer
* Windranger's highly mobile playstyle allows her to easily control Lifestealer from a distance, as he has no disables on his own. Windrun not only provides her with bonus move speed, but evasion as well, undoing Lifestealer's ability to attack her. In combination with Focus Fire, Windranger can easily dispose of Lifestealer without him being able to reach her.
Templar Assassin
* Ensnare disables Templar Assassin's invisibility and Blink Dagger (a core item on Templar Assassin), and her illusions will break Refraction easily.
Lifestealer
* Heroes with illusions: 
Chaos Knight, 
Naga Siren, 
Phantom Lancer, 
Terrorblade
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.
Lifestealer
* Lifestealer cannot use Rage, 
Infest or 
Open Wounds when affected by Smoke Cloud's silence, and Feast cannot heal him effectively because of the blind, leaving him very weak both offensively and defensively.
* Infest ganks are harder when the enemy team has a Riki, as there are often only four heroes on the map that you can initiate on.
Templar Assassin
* Ion Shell destroys Refraction's protection stacks in short time.
* Surge ignores the massive slow from 
Psionic Trap.
Lifestealer
* Heroes with escape abilities : 
Anti-Mage 
Dark Seer 
Slark 
Storm Spirit 
Windranger 
Weaver can kite Lifestealer due to him having no lockdown
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.
Lifestealer
* Razor's highly mobile nature allows him to control Lifestealer from a distance. As well, Lifestealer is already slow in comparison due to his lack of disables and move speed. Lifestealer is also an ideal target for Static Link, for its ability to pierce magic immunity and damage steal, which can render Lifestealer's Feast useless.
* Plasma Field can slow Lifestealer from a distance and force him to cast Rage too early.
* Eye of the Storm pierces magic immunity, deals physical damage, and reduces armor, allowing Razor to easily stand up to Lifestealer.
Additional:
* Static Link cannot be dispelled by Rage or Infest, so Razor will be able to track Lifestealer down during an attempted escape.
* Storm Surge makes it hard for Lifestealer to catch Razor.
* Static Link can stop Open Wounds from getting any additional lifesteal, but keep in mind Lifestealer can still utilize Feast.
* Eye of the Storm penetrates the spell immunity of Rage.
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.
Lifestealer
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: 
Phantom Assassin,
Bloodseeker, 
Lifestealer, 
Troll Warlord, 
Sven
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.
Lifestealer
* Heroes with high physical damage can damage Lifestealer more than he can heal: 
Bristleback, 
Clinkz, 
Luna,
Shadow Fiend, Slardar, Terrorblade
Templar Assassin
* Multiple attackers thanks to summoned units or clones: 
Meepo, 
Witch Doctor, 
Lycan, 
Enigma, 
Shadow Shaman
* 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
Lifestealer
* Heroes with summons: Lycan, 
Broodmother, 
Visage, 
Nature's Prophet, Warlock.
Templar Assassin
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like 
Keeper of the Light, Luna, Templar Assassin...
Lifestealer
* Special mention to Lifestealer who can use Rage to prevent Trample damage, but Pulverize can still stun and do damage.
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.
Lifestealer
* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin can have their damage mitigated by Cold Embrace.
Templar Assassin
* Shackles and Mass Serpent Ward instantly destroy Refraction
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.
Lifestealer
* Though 
The Swarm can be blocked by Rage, it can be used to lower Lifestealer's already low armor, making him even more vulnerable to physical damage while Rage is on cooldown.
* Lifestealer has no strong disables on his own and thus cannot catch up with nor escape from Weaver's 
Shukuchi.
* Lifestealer's reliance on meticulous auto-attacks will not help against 
Time Lapse, which can undo Lifestealer's already slow build-up of damage. 
Aghanim's Scepter upgraded Time Lapse can also be used to save allies from getting killed by Lifestealer, but that will require targeting the allied hero rather than just pressing the button that will trigger the Time Lapse.
Additional:
* Open Wounds's slow is ignored by Shukuchi.
* Lifestealer has no other lockdown and relies on being on top of enemies; Weaver can kite him with ease.
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.
Lifestealer
* Heroes that rely on slows to get kills: Lifestealer, 
Night Stalker, 
Ursa, Phantom Assassin, Terrorblade.
Lifestealer
* Lifestealer's Rage negates Sand King's spells which do magical damage.
Lifestealer
* Chronosphere provides excellent lockdown against Rage.
* Faceless Void's Time Lock stops Lifestealer from getting health regeneration from auto-attacks
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.
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
* 
Blade Fury's damage over time dispels Refraction almost instantly.
* Juggernaut's high armor allows him to survive for long enough to remove Refraction and threaten her with 
Omnislash as long as he or his team carries detection.
* Templar Assassin's short attack range makes it difficult for her to target a well-placed 
Healing Ward. She cannot splash onto it with 
Psi Blades.
Templar Assassin
* Attacks from Boars and the attack speed boost from Inner Beast will quickly wear down Refraction.
Lifestealer
* Reverse Polarity pierces through Rage, wasting part of it's duration.
* Magnus is tanky and mobile, making it hard for Lifestealer to focus and kill him in all stages of a game.
Lifestealer
* 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.
Additional:
* Although Lifestealer can avoid Eclipse with Rage and Infest, Luna's physical damage from 
Moon Glaives and 
Lunar Blessing 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 Aghanim's Scepter upgraded Infest can disarm Luna and allow Lifestealer to attack her from inside even if she is spell immune, Luna can easily counter this with 
Linken's Sphere, which is a common item on Luna.
Templar Assassin
* 
Bushwhack can tear through Refraction as it does multiple intervals of damage.
Lifestealer
* Lifestealer's low mobility makes him easy to kite.
* Stone Gaze pierces Rage, wasting its cooldown and making Lifestealer unable to fight.
Templar Assassin
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* 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
Lifestealer
* Lacking any stun and being heavily dependent on his physical attacks and spell immunity, Lifestealer has no way to stop 
Black Hole , assuming he does not initiate Enigma first with 
Abyssal Blade.
* Enigma's Black Hole and Midnight Pulse damage can pierce through Lifestealer's Rage.
* However, if Lifestealer manages to get Aghanim's Scepter and combines it with Abyssal Blade, he will be able to disable Enigma's Black Hole inside him with Infest and he will be able to help his allies recover themselves from Enigma's initiation with Open Wounds if Lifestealer gets Aghanim's Shard.
Lifestealer
* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: 
Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, 
Abaddon, Wraith King, Lifestealer.
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
Lifestealer
* Lifestealer is a great target for Morphling to use Morph, as he can use Rage to gain spell immunity and a movement speed boost.
* Morphling's high armor also makes Lifestealer's attacks do less damage.
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.
Lifestealer
* Since 
Untouchable pierces Spell Immunity, Lifestealer cannot burst her down even with Rage; meaning she can heal herself back to full HP.
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.
Lifestealer
* Terrorblade's illusions and ranged attacks in 
Metamorphosis can burst down Lifestealer very quickly.
* Terrorblade has low health due to his low strength gain, which reduces Feast's lifesteal and damage.
* Because Lifestealer can usually heal back HP in fights due to his innate lifesteal (and sometimes 
Armlet of Mordiggian), he is a great target for Terrorblade's Sunder.
Additional:
* Reflection's illusion carries Feast as well, making it useful to use against him.
* Feast cannot compensate for Terrorblade's incoming high damage, due to his low Strength gain.
* Open Wounds (requires Aghanim's Shard) is a lot harder to land on the real Terrorblade if he has illusions around him. But remember that Terrorblade's illusions from 
Conjure Image have different colors than other illusions which can be seen even by enemy team, and that can make it easy for Lifestealer to detect real Terrorblade unless Terrorblade buys Manta Style.
* Lifestealer relies on right-clicks to deal damage, and Terrorblade's high armor can reduce his damage significantly.
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.
Lifestealer
* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
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.
Lifestealer
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or 
Juggernaut or heroes that tend to pick up 
Black King Bar, like Sven.
Lifestealer
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Lifestealer
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Templar Assassin
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* 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
Lifestealer
* Lifestealer's Rage and Open wounds become useless when Meepo has 4 or more clones, as Ransack will heal Meepo too quickly for Lifestealer to take down.
Lifestealer
* Lifestealer is not affected by Earthbind or Poof during Rage, making him a difficult target to work around.
Lifestealer
* Heroes with spell immunity can still be disabled by Fiend's Grip: Juggernaut, Lifestealer, 
Pangolier.
Additional:
* 
Enfeeble can weaken Lifestealer's Feast and may force him to cast Rage too quickly or itemize to dispel it.
* 
Fiend's Grip pierces through magic immunity and allows him to disable Lifestealer while in Rage.
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.
Lifestealer
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
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
* 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
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
* 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.
Lifestealer
* Melee carries such as Sven, Ursa or Lifestealer can be slowed and easily kited with Demonic Purge.
Lifestealer
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, Slardar, Terrorblade
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.
Lifestealer
* Heroes with escape abilities : Anti-Mage Dark Seer Slark Storm Spirit Windranger Weaver can kite Lifestealer due to him having no lockdown
Lifestealer
* Heroes that lack burst damage will have a difficult time taking down Monkey King, and fare badly against Jingu Mastery: 
Legion Commander, Lifestealer, Weaver, Wraith King
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.
Lifestealer
* Heroes with good escape mechanisms are a nuisance to deal with in the early phase of the game: Slark, Lifestealer, Morphling
Lifestealer
* Lifestealer is a susceptible target to 
Fervor due to his non-mobile nature and lack of disables. Troll Warlord's ranged 
Berserker's Rage can also be used to kite Lifestealer safely. The root from its melee form also pierces magic immunity, which can potentially keep Lifestealer in place even while he is in Rage.
* Both 
Whirling Axes (melee) and 
Whirling Axes (ranged) can force Lifestealer to cast Rage too quickly and allow Troll Warlord to change strategies mid-fight, especially thanks to their separate cooldowns.
* 
Battle Trance allows Troll Warlord to survive Lifestealer's Feast and turn the fight in his favor.
Additional:
* The passive armor provided by Berserker's Rage makes Troll Warlord resilient to Feast in early game.
* The 60% miss chance given by Whirling Axes (Melee) is useful when Rage is not active.
* Battle Trance can purge Open Wounds, negating a large amount of Lifestealer's sustain in fights.
Lifestealer
* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
Lifestealer
* Clinkz relies heavily on the physical damage provided by 
Burning Barrage and 
Searing Arrows, which completely overrides the capabilities of Rage.
* Lifestealer's lack of disables will struggle to pin Clinkz down while in 
Skeleton Walk, and can allow Clinkz to kite him.
Templar Assassin
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: 
Sniper, 
Drow Ranger, Clinkz
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 (and can be re-apply 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.
Lifestealer
* 
Ice Blast prevents Lifestealer from lifestealing and healing with Infest in fights.
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
* 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.
Lifestealer
* Heroes with spell immunity-granting spells will render Phoenix useless against them, as Phoenix has almost no spell immunity-piercing ability, other than the stun at the end of Supernova: Lifestealer, Juggernaut.
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
* Refraction can be very useful in safely neutralizing Proximity Mine fields, or absorbing Techies' Blast Off combo.
Lifestealer
* Rage protects Lifestealer from all of Techies' abilities. 
Reactive Tazer's disarm will also not work on Lifestealer under Rage.
* Rage can also be used to trigger Techies' 
Proximity Mines safely.
Additional:
* Lifestealer's Rage lets him clear Proximity Mines without taking damage, and allows him to hit heroes whom Techies has used Reactive Tazer on.
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.
Lifestealer
* Feast is an effective tool against Centaur Warrunner, who generally has high health and low armor, and compensates the reflected damage of Retaliate.
* If activated, Rage can protect Lifestealer from Hoof Stomp, Double Edge, and Stampede.
Additional:
* Centaur Warrunner's active abilities cannot pierce magic immunity. 
Hoof Stomp's slow wind up can also be anticipated and negated with Rage.
* Lifestealer can offset 
Retaliate's damage return simply with Feast. Centaur's high strength gain and therefore big health pool makes him an ideal target to Feast on, especially in the late-game.
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.
Lifestealer
* Rage prevents Earthshaker from damaging and stunning Lifestealer.
* Feast is very effective against Earthshaker, because of him being a strength hero, allowing Lifestealer to heavily harass and kill him.
* Open Wounds prevents Earthshaker from escaping after he initiated.
* Infest gives Lifestealer an easy way to escape should he get caught out by Earthshaker. And against carry Earthshaker, Aghanim's Scepter upgraded Infest can be used to disarm Earthshaker and attack him from within, rendering him unable to attack with 
Enchant Totem.
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.
Lifestealer
* Rage grants immunity from Invoker's spells and can dispel most of the disables such as the armor loss from Forge Spirit and the constant stuns of Cold Snap.
Additional:
* Rage protects Lifestealer from all of Invoker's spells (except for 
Sun Strike).
Templar Assassin
* Heroes that can jump and kill him: Meepo, Clinkz, Templar Assassin
Lifestealer
* Rage allows him to be immune to all of Ezalor's abilities. Also, the increased movement speed combined with the slow from Ghoul Frenzy and the squishy nature of Ezalor allows Lifestealer to take him down very quickly.
Templar Assassin
* Refraction negates all of Void Spirit's burst damage.
* Meld quickly burns through 
Resonant Pulse.
Lifestealer
* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like Ursa, Lifestealer, or 
Axe.
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
Lifestealer
* Lifestealer can close the distance to Sniper by using Infest on a fast or durable creep to tank Sniper's damage.
* Open Wounds and Ghoul Frenzy will reduce Sniper's mobility heavily, and Rage's movement speed bonus helps in closing the gap to Sniper. It also protects him from Assassinate and Shrapnel.
* Infest can dodge an incoming Assassinate.
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
Lifestealer
* Rage can protect Lifestealer from most of the Silencer's abilities with the exception of 
Global Silence, as it will still silence if cast while the target is magic immune. However, it will not work if Lifestealer is infesting a unit.
* Silencer is vulnerable to Open Wounds due to his lack of an innate escape.
* Against a carry Silencer, Aghanim's Scepter upgraded Infest can disarm him and allow Lifestealer to attack Silencer from within, even if Silencer is spell immune.
Additional:
* Rage can protect Lifestealer from most of the Silencer's abilities with the exception of Global Silence.
* If Lifestealer can Infest himself on any unit, he can literally avoid being affected by Global Silence.
* Against a carry Silencer, Aghanim's Scepter upgraded Infest can disarm him and allow Lifestealer to attack Silencer from within, even if Silencer is spell immune.
* Open Wounds from Aghanim's Shard can severely slow down Silencer, and allow Lifestealer and his team to heal themselves by attacking Silencer.
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.
Lifestealer
* Heroes with built-in spell immunity can become immune to all of Outworld Destroyer's spells: Lifestealer's Rage and Juggernaut's Blade Fury.
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
Lifestealer
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, Lina, 
Lion, Zeus.
Additional:
* Rage protects Lifestealer from all of Lina's abilities (except an upgraded Laguna Blade).
* Open Wounds is great to keep Lina in place because she has no abilities to help her escape.
Lifestealer
* Rage, acting as a pseudo-Black King Bar, completely negates Mars' initiation if used in time.
* Feast does damage and heals based on max health, perfect against high-health strength heroes like Mars.
* Infest allows Lifestealer to potentially save allies from Mars' initiation with a quick burst of extra health.
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).
Lifestealer
* Feast will deal a enormous amount of damage because of Tiny's huge health pool.
* Rage protects Lifestealer from Tiny's magical burst damage.
Lifestealer
* Rage can be used to escape from a Glimpse and to move out of Kinetic Field.
* Infest allows Lifestealer to dodge Glimpse.
Lifestealer
* With Feast and Rage, Lifestealer is nearly impossible for Clockwerk to bring down, and is the last hero Clockwerk wants to be trapped with in Power Cogs.
Lifestealer
* Lifestealer's Rage renders him immune to all of Marci's disables and magic damage for a good duration.
* His passive Feast deals bonus damage based on the enemy's max health and heals for the same amount. As a tanky Strength hero, Marci's own strength will be her undoing as well.
Lifestealer
* Rage protects and dispels all of Dark Willow's abilities.
Additional:
* Rage protects Lifestealer from all of Dark Willow's abilities.
Lifestealer
* Feast makes it impossible to for Lifestealer to be culled with 
Culling Blade and also deals high damage to Axe due to his naturally high health. However, Rage can still be pierced by 
Berserker's Call and 
Counter Helix.
Lifestealer
* Feast is good against high health strength heroes such as Alchemist.
* Rage allows Lifestealer to not be targetable by Unstable Concoction, possibly making Alchemist stun himself.
Lifestealer
* Lifestealer can activate Rage to become spell immune, making Pierce the veil do no damage and preventing Dead Shot from fearing or doing damage.
* Lifestealer can use Infest to avoid Muerta's Gunslinger shots and Dead Shot's fear.
Lifestealer
* Feast deals damage and heals lifestealer based on the target max health. Because Spectre often emphasises on building stat items to increase her HP pool, lifestealer can deal a lot of damage to her and heal himself at the same time.
* Ghoul Frenzy slows target, which is bad for Spectre if she does not have 
Spectral Dagger ready.
* Spectre cannot response to infest if lifestealer choose to stay inside his high mobility allies to approach the backline. Rage's bonus movement speed and spell immunity make it even more frustrating.
Lifestealer
* Being a strength hero with a high strength gain means Feast can give her a hard time,especially later in the game.
* However,
Starbreaker's physical damage can control him in the laning phase.
Templar Assassin
* Sven has no easy way to burn Refraction charges and needs help from teammates to kill TA successfully.
Lifestealer
* Lifestealer is able to endure Undying, especially in the laning phase, where Undying is strongest. Feast can offset 
Decay's strength steal for its percentage lifesteal. Rage delays Undying from stealing strength and can help Lifestealer destroy Undying's 
Tombstone uninterrupted. As well, none of Undying's abilities pierce magic immunity.
Lifestealer
* Like with Juggernaut's Blade Fury, Rage allows Lifestealer to freely attack Nyx Assassin and hunt him down if Vendetta is on cooldown. Nyx Assassin cannot counter Rage with Spiked Carapace because Rage gives Lifestealer spell immunity. And besides Vendetta, Nyx Assassin has no other way of dealing damage to Lifestealer while he is spell immune.
* Open Wounds from Aghanim's Shard allows Lifestealer to severely slow down Nyx Assassin while also allowing his team to recover themselves while attacking Nyx Assassin. Open Wounds can also fester and spread if Nyx Assassin takes enough damage that will trigger the spread while he is affected with Open Wounds.
* Infest combined with an ancient creep makes Nyx Assassin an easy target to surprise with Dust of Appearance or a 
Gem of True Sight. And similarly to Juggernaut's Omnislash and 
Swiftslash from Aghanim's Scepter, Aghanim's Scepter upgraded Infest can also allow Lifestealer to infest, disarm and freely attack Nyx Assassin from within. and Nyx Assassin cannot counter this with Spiked Carapace because Lifestealer is invulnerable while attacking the infested enemy hero from within.
* Like with Juggernaut, any attempt for Nyx Assassin to gank and kill Lifestealer will hurt Nyx Assassin more than Lifestealer.
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.
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.
Lifestealer
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, Lina, Lion, Zeus.
Additional:
* Rage is very useful against Zeus, as it negates magic damage and provides spell immunity. In addition, the increased attack speed can tear Zeus apart in combination with Open Wounds.
* Lifestealer can avoid Thundergod's Wrath with Infest.
Lifestealer
* Lifestealer's Rage makes him immune to all of Tinker's damage and debuffs.
* Lifestealer can infest a mobile ally (teams usually pick one against Tinker), which may ensure that Tinker will die if he is caught.
Additional:
* Rage will dispel Laser's blind and turns him spell immune for the duration so Tinker cannot damage him.
* Feast will quickly bring down Tinker due to being so fragile.
Lifestealer
* Rage gives Lifestealer spell immunity, Chen and his converted creeps have little to no ways of fighting back against Lifestealer whenever he activates it.
* Feast allows Lifestealer to recover himself by damaging Chen's creeps.
* Chen has no escape mechanisms, so he will often be unable to escape from slows applied with Ghoul Frenzy.
* Open Wounds from Aghanim's Shard can severely slow down Chen, and allow Lifestealer and his team to heal themselves by attacking Chen. Open Wounds can also fester and spread if Chen takes enough damage that will trigger the spread while he is affected with Open Wounds.
* Infest allows Lifestealer to infest into one of Chen's converted creeps and take control of it, which allows Lifestealer to either escape from Chen or surprise him. Aghanim's Scepter upgraded Infest can disarm Chen and allow Lifestealer to attack Chen from within, even if Chen is spell immune.
Lifestealer
* Rage negates Kunkka's X Marks the Spot.
* As a strength hero with high strength gain and very little armor, as well as low agility gain, Kunkka is vulnerable to Lifestealer's Feast and Open Wounds.
Lifestealer
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, Lina, Lion, Zeus.
Additional:
* Rage provides debuff immunity and increased magic resistance, thus drastically reducing magical damage and preventing most of disables (in Lion's case, all are fully blocked) making it nearly impossible to defend against or to punish a raging Lifestealer.
* Lack of inner escape and defensive mechanisms increases Ghoul Frenzy effectiveness, since it applies slows upon auto attacking.
* Lifestealer damage output is too powerful against Lion's low health and base armor
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
* 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
* 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
Lifestealer
* Lifestealer, at even farm levels, will often fall against other man-fighting non-Strength cores like Ursa, Phantom Assassin or Troll Warlord as he cannot truly rely on sustain from Feast.
Additional:
* Rage does absolutely nothing against Phantom Strike with items.
* Feast and Ghoul Frenzy are very difficult to utilise thanks to Blur.
* Lifestealer generally wants to buy items that make him hard to kill, not an 
Monkey King Bar which only offers damage.
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
Lifestealer
* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
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.
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
Lifestealer
* Feast deals damage and heals Lifestealer based on the target's maximum HP, which is greatly effective against naturally high HP heroes such as Doom.
* Rage allows Lifestealer to become spell immune to negate the magical damage of Infernal Blade and Scorched Earth.
* Doom has no effective means of escape from Open Wounds. This is particularly devastating in lane, where Doom may have to play a much more passive, conservative play style as a result.
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.
Lifestealer
* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and 
Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.
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.
Lifestealer
* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, 
Omniknight, 
Huskar , and Tusk have spells which allow them to easily escape Dream Coil.
Lifestealer
* Heroes with escape abilities : Anti-Mage Dark Seer Slark Storm Spirit Windranger Weaver can kite Lifestealer due to him having no lockdown
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.
Lifestealer
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, Slardar, Terrorblade
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.
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
Lifestealer
* Rage ignores all of Gyrocopter's magical attacks.
* Feast helps Lifestealer out-damage Gyrocopter at close range.
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
Lifestealer
* Juggernaut and Lifestealer have abilities (Blade Fury and Rage respectively) that prevent Crystal Maiden from using her spells on them in the early game, before Black King Bar and other magical reduction is even an issue.
Additional:
* Crystal Maiden is an ideal target for Lifestealer due to her poor mobility and low health pool. Lifestealer can usually catch up to her simply by casting Rage, as none of her abilities pierce through magic immunity. 
Freezing Field can potentially make her even more vulnerable to Lifestealer while under Rage as she is even more immobile while channeling it.
* Lifestealer commonly buys Abyssal Blade, which allows him to cancel Freezing Field, even if Crystal Maiden is spell immune.
* Alternatively, Aghanim's Scepter upgraded Infest combined with Abyssal Blade and with items that provide attack speed which Lifestealer commonly buys allow him to to cancel Freezing Field from within the Crystal Maiden.
Lifestealer
* Lifestealer will struggle to duel Ursa in all stages of the game due to 
Fury Swipes, which pierces magic immunity. Ursa can also stand up to Lifestealer with 
Enrage, which dramatically reduces incoming damage and further delay Lifestealer's Feast.
Additional:
* Lifestealer's Feast will most likely not out-heal the damage from Fury Swipes and Overpower in the early to mid game.
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.
Lifestealer
* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
Templar Assassin
* Firestorm will destroy Refraction charges very quickly.
* Firestorm will hit Templar Assassin while under the effects of Meld Meld.
* Templar Assassin has a hard time maneuvering around Pit of Malice.
Templar Assassin
* In general, heroes that provide vision will see Fiend's Gate coming: 
Techies, Templar Assassin, Treant Protector
Lifestealer
* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.
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.
Lifestealer
* The lifesteal of Feast scales accordingly to the max health of its target, which is effective against Pudge due to his high health and further health granted by stacks of Flesh Heap.
* Lifestealer can activate Rage to be spell immune, making Rot deal no damage.
* Pudge's plentiful health makes him an ideal target for Lifestealer's Aghanim's Shard ability, Open Wounds.
Templar Assassin
* 
Pulse Nova can easily burn Templar Assassin's Refraction charges quickly, and can also hit her with her Meld.
Lifestealer
* Leshrac's high magic damage is ignored by Rage.
* Lifestealer can get in Leshrac's face with Rage and mitigate any other damage taken by Leshrac with Open Wounds.
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.
Lifestealer
* Lifestealer's Rage makes him immune to all of Ogre's magical debuffs and also dispels them.
* Ogre's high health pool makes him an ideal target for Feast.
Additional:
* Ogre Magi has nothing against Rage and his high health pool amplifies Feast.
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.
Lifestealer
* Lifestealer with Rage and Infest
* Heroes that can remove the Track debuff with their skills:
* Abaddon with 
Aphotic Shield and 
Borrowed Time
* Huskar with 
Life Break
* Juggernaut with Blade Fury
* Legion Commander with 
Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with 
Mirror Image
* Omniknight with 
Heavenly Grace
* 
Oracle with 
Fortune's End and 
False Promise
* Phantom Lancer with 
Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* 
Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Templar Assassin
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* 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
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
* 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 traditionally forgoes health and armor items for damage. Outside of Black King Bar, Viper will almost always be able to kill her when Refraction is down.
Lifestealer
* Rage ignores all of Viper's magical damage, although Viper Strike can pierce spell immunity and slows him down.
* Feast and Open Wounds from Aghanim's Shard can be combined to heal through Viper's physical damage.
* Aghanim's Scepter upgraded Infest can be used to disarm Viper, preventing him from using Poison Attack on Lifestealer's allies.
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.
Lifestealer
* Rage grants Lifestealer immunity to all of Jakiro's spells. Note: magic resistance will not dispel the attack speed slow effects from Dual Breath and Liquid Fire.
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.
Lifestealer
* Rage renders Lifestealer immune to the damage from Burning Spears.
* Feast makes Lifestealer one of few heroes that can outlast Huskar in a one-on-one fight.
Lifestealer
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Lifestealer
* Heroes with magic immune abilities can negate most of Visage's attacks like Pangolier and Lifestealer.
Templar Assassin
* Phantom Lancer's illusions destroy
Refraction charges very quickly.
Lifestealer
* Lifestealer will struggle to deal with Phantom Lancer's illusions and will either be forced to use his abilities too quickly, or itemize too heavily for them.
Diffusal Blade, which poses a large problem to Lifestealer and his low mana pool, and can shut him down from even casting his abilities.
Phantom Rush.
Doppelganger dispels 
Open Wounds.
Diffusal Blade, which a problem for a low already mana hero like Lifestealer.
* Phantom Lancer commonly builds
Additional:
* Aside from his ultimate, Lifestealer has no AoE abilities to deal with Phantom Lancer's illusions, nor does he have the mobility to escape
*
* Phantom Lancer usually builds
