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.
Abaddon
* Because Poison Attack has almost no cooldown, Aphotic Shield is ineffective as a hard dispel.
* Viper Strike can prevent 
Borrowed Time from activating passively and block 
Curse of Avernus.
Additional:
* Because Poison Attack has almost no cooldown, 
Aphotic Shield is ineffective as a hard dispel.
* Viper Strike can prevent Borrowed Time from activating passively and block Curse of Avernus.
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.
Abaddon
* {U:Storm} can use 
Cyclone on Abaddon when he activates Borrowed Time, wasting its duration.
* 
Drunken Brawler and 
Thunder Clap hinder Abaddon from applying Curse of Avernus' silence on him.
Additional:
* Dispel Magic can remove Abaddon's Aphotic Shield or Curse of Avernus on an allied hero.
* Cyclone's lengthy duration wastes much of Borrowed Time's duration.
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
Abaddon
* 
Doom will make Abaddon unable to use Mist Coil, Aphotic Shield, and the active component of Borrowed Time, also upgraded with 
Aghanim's Scepter can break Curse of Avernus and the passive component of Borrowed Time ,which means his allies could be easily disabled or killed.
Templar Assassin
* Ensnare disables Templar Assassin's invisibility and Blink Dagger (a core item on Templar Assassin), and her illusions will break Refraction easily.
Abaddon
* 
Song of the Siren completely wastes Abaddon Borrowed Time while keeping him in place.
* Naga Siren is able to simply dispel Abaddon's Curse of Avernus with 
Mirror Image before getting hit 4 times consecutively.
* Although Naga Siren's illusions can be easily destroyed by Aphotic Shield, Naga Siren can resolve that issue easily by purchasing 
Heart of Tarrasque to drastically increase her durability. Plus, the said item makes Naga Siren harder to be distinguished from her illusions.
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.
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.
Abaddon
* 
Culling Blade's instant kill is not prevented by Borrowed Time should Abaddon's health falls below the threshold.
Additional:
* Culling Blade ignores Borrowed Time should Abaddon's health falls under the threshold.
* Aphotic Shield does nothing against Berserkers Call and has to be used constantly to remove the very small mana cost of Battle Hunger in lane.
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
* 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.
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.
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.
Abaddon
* Shadow Demon with an Aghanim's Scepter will use 
Demonic Purge to disable Curse of Avernus and the passive component of Borrowed Time. If this is combined with a silence, Borrowed Time will not trigger at all.
* Even without Aghanim's Scepter, he can still waste Borrowed Time with 
Disruption. Curse of Avernus fully works on illusions, turning the passive ability against him.
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.
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.
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
* 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.
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.
Abaddon
* Reflection will cause Abaddon to be afflicted by his own Curse of Avernus, silencing and slowing him. The reflection is also hard to avoid, as it cannot be killed, only dispelled.
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.
Abaddon
* Heroes who can negate effects of Sunder: Faceless Void's 
Time Walk, 
Weaver's 
Time Lapse, 
Broodmother's 
Insatiable Hunger, 
Abaddon's Borrowed Time and 
Troll Warlord's 
Battle Trance can nullify Sunder.
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
* 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
* 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.
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:

* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Abaddon
* Heroes that have long silences, such as 
Night Stalker and Silencer, will prevent Abaddon from saving his allies effectively and disable the active component of Borrowed Time.
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
* 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
* 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.
Abaddon
* 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.
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.
Abaddon
* Heroes that deal damage over time will also fail to bring down Abaddon and his allies, such as 
Huskar, 
Venomancer, or 
Phoenix.
Additional:
* Huskar's damage over time gives Abaddon the opportunity to shield and heal his allies.
* Borrowed Time also makes Abaddon a hard support to gank, thus negating Huskar's early game dominance.
Abaddon
* 
Ice Blast's nullifies Abaddon healing from Borrowed Time and Mist Coil and it is not dispelled by Aphotic Shield.
Additional:
* Ice Blast nullifies Borrowed Time's and 
Mist Coil's healing.
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
* Shackles and Mass Serpent Ward instantly destroy Refraction
Abaddon
* By simply using Aphotic Shield, Abaddon can easily save his allies from heroes that apply long disables, such as 
Lion or Shadow Shaman.
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.
Abaddon
* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as 
Skywrath Mage, 
Techies, 
Juggernaut, Shadow Shaman, or 
Ogre Magi.
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.
Abaddon
* Heroes that deal damage over time will also fail to bring down Abaddon and his allies, such as Huskar, Venomancer, or Phoenix.
Templar Assassin
* 
Track provides vision on Templar Assassin during her Meld, allowing him and his teammates to gank her often until she buys a Black King Bar or the {ValueColor:1|Meld Dispels|20tal} {Symbol:Talent} talent to dispel it.
Additional:

Abaddon
* Abaddon with Aphotic Shield and Borrowed Time
* 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

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
* 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.
Abaddon
* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as Skywrath Mage, Techies, Juggernaut, Shadow Shaman, or Ogre Magi.
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.
Abaddon
* Heroes that can deny Slark early kills will prevent him from snowballing: 
Dazzle, Abaddon.
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.
Abaddon
* Abaddon's constant heals and protection can save himself and his allies from burst-focused heroes, such as Legion Commander, Faceless Void, and 
Pudge.
Additional:
* Abaddon can activate Borrowed Time to dispel Dismember; breaking the disable and potentially allowing Abaddon to escape.
* Aphotic Shield can be cast on an ally to dispel the stun of Dismember, which can make kills difficult to secure, given that Dismember is Pudge's only reliable disable.
* Pudge lacks a mobility without a Blink Dagger, causing him to be easily chased with Curse of Avernus. The silence also prevents him from toggling off his Rot.
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
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.

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
* 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.
* 
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.
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.
Abaddon
* Aphotic Shield makes it less likely for allies to be killed by mines.
* Because they explode in very short intervals, a stack of 
Remote Mines will always trigger Borrowed Time, making them impossible to kill Abaddon unless his resistances are lowered enough or Abaddon is affected by Break.
* Abaddon can easily dispel the long-lasting root of 
Stasis Trap on himself and on an ally, while at the same also providing protection against the other mines' damage.
Additional:
* Borrowed Time's automatic activation will help Abaddon survive a field of Proximity Mines or a Blast Off combo. However, the damage from a single mine can kill him if his HP is low enough.
* Aphotic Shield's can easily break Techies' Etheral Blade combo.
Templar Assassin
* Refraction negates all of Void Spirit's burst damage.
* Meld quickly burns through 
Resonant Pulse.
Abaddon
* Heroes that can purge his slow and disables are very difficult to go on and their team: Abaddon, Oracle.
Templar Assassin
* Templar Assassin easily withstands all the damage from Skyrwrath Mage, thanks to its first ability Refraction. In addition, Templar Assassin can kill Skywrath Mage with a single hit from under the second ability Meld.

* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as Skywrath Mage, Techies, Juggernaut, Shadow Shaman, or Ogre Magi.
Additional:
* Aphotic Shield removes silences, slows and stuns, possibly foiling a full-duration Mystic Flare.
* Borrowed Time makes it impossible to burst Abaddon down, even healing him up due to Mystic Flare's damage.
Abaddon
* Aphotic Shield can nullify Chen's combo, while clearing Chen's creeps simultaneously.
Templar Assassin
* 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.
Additional:
* 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. However, he may easily burn through Refraction with 
Chakram.
Abaddon
* Borrowed Time mitigates the damage by Pierce the Veil for most of its duration.
* Muerta has no control over Gunslinger, making her one of the best heroes for Abaddon to regenerate from via Borrowed Time.
Abaddon
* Aphotic Shield prevents damage and dispels the slow from Snapfire's 
Mortimer Kisses.
* Borrowed Time allows Abaddon to gain HP during Snapfire's Mortimer Kisses.
Templar Assassin
* Sven has no easy way to burn Refraction charges and needs help from teammates to kill TA successfully.
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.
Abaddon
* 
Exorcism will continuously heal Abaddon under Borrowed Time, and cannot be turned off.
* {Ability ID:Spirit Siphon|Death Prophet} will continuously heal Abaddon under Borrowed Time, for a percentage of his maximum health.
Abaddon
* If he isn't silenced, Abaddon can use Borrowed Time to escape 
Reaper's Scythe during the delay.
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.
Abaddon
* If he isn't broken (break), Abaddon can use Borrowed Time to waste Legion Commander's 
Duel, As Borrowed Time has a shorter cooldown, Legion Commander can't win duels, effectively reducing her targets by one, Duel also means that Borrowed Time heals Abaddon for the duration of the duel, as Legion can't stop attacking.
Additional:
* Aphotic Shield and Mist Coil makes it hard for Legion Commander to kill Abaddon's teammates in Duels.
* Borrowed Time makes Abaddon nearly impossible to kill in Duels, and often replenishes much of his health because Legion Commander cannot manually stop attacking during Duels.
Abaddon
* 
Sacred Arrow can be instantly dispelled by Aphotic Shield.
Additional:
* Abaddon can remove Sacred Arrow's stun from his teammates with Aphotic Shield, or remove it from himself with Borrowed Time.
* Borrowed Time makes Abaddon almost impossible to burst down with Mirana's Aghanim's Scepter combo.
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.
Abaddon
* 
Nightmare and 
Fiend's Grip can be instantly dispelled by Aphotic Shield.
* Bane lacks mobility, therefore becoming helpless when silenced by Curse of Avernus.
Additional:
* Aphotic Shield applies a strong dispel on the allied target and can be used to remove both Fiend's Grip & Nightmare.
* Borrowed Time applies a strong dispel on Abaddon and can instantly remove both Fiend's Grip & Nightmare when activated.
* Bane, when caught by Curse of Avernus will struggle to escape because of his innately low mobility.
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.
Abaddon
* Aphotic Shield dispels Thunder Strike.
* Mist Coil can be used to heal an ally trapped by Static Storm-Kinetic Field combo.
* Borrowed Time makes Abaddon nearly impossible to gank.
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
Abaddon
* Lina is a common 
Eul's Scepter of Divinity carrier which can waste some duration of Borrowed Time and following up with 
Laguna Blade if timed correctly.
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
Abaddon
* Both Lion's 
Finger of Death and Lina's Laguna Blade have a 0.25 second delay before the damage is dealt.
Abaddon
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, 
Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Destroyer.
Abaddon
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, 
Alchemist, Dragon Knight, Night Stalker, Viper.
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
Abaddon
* Abaddon's constant heals and protection can save himself and his allies from burst-focused heroes, such as Legion Commander, Faceless Void, and Pudge.
Additional:
* Mist Coil and Aphotic Shield enable Abaddon to keep an ally alive during Chronosphere.
* Borrowed Time prevents Faceless Void from killing Abaddon during his Chronosphere.
Templar Assassin
* Heroes that can jump and kill him: Meepo, Clinkz, Templar Assassin
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
Abaddon
* Both Lion's Finger of Death and Lina's Laguna Blade have a 0.25 second delay before the damage is dealt.
Additional:
* Aphotic Shield applies strong dispel on targeted allies, while Borrowed Time does the same on Abaddon himself upon both casts (manually or automatically), removing disables, such as 
Earth Spike and 
Hex.
* Abaddon may offer survivability to Lion's nuke power by shielding and healing allies and himself.
* Lack of inner escape and defensive mechanisms increases Curse of Avernus effectiveness, since it slows per stack (applied upon auto attacking), and silences when it reaches the maximum stack.
Templar Assassin
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz
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.
Templar Assassin
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz
Abaddon
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying 
Dagon and 
Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: Faceless Void, 
Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.
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
* 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
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
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.
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
Abaddon
* Borrowed Time can give Abaddon a second chance after a Black Hole combo.
* Aphotic Shield can be used to save allies or Abaddon himself from Malefice.
* Abaddon can easily heal himself as well as his allies during a team fight, especially with Aghanim's Scepter upgraded Borrowed Time.
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.
Abaddon
* If 
Rupture is used on Abaddon, Abaddon can use Borrowed Time and easily heal for the duration of Borrowed Time by simply moving.
Additional:
* Borrowed Time makes Abaddon nearly impossible to gank.
* Aphotic Shield and Mist Coil prevents Bloodseeker from gaining his Thirst bonuses.
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.
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.
Abaddon
* Abaddon can cast Aphotic Shield on any of his allies to immediately dispel Corrosive Haze and/or the stun and the slow components of Slithereen Crush.
* All of Slardar's debuffs are also removed if Abaddon's Borrowed Time triggers.
Abaddon
* Nyx Assassin might not kill Abaddon with his nuke, but a support Abaddon will struggle to protect an ally from him.
Abaddon
* 
Impale and 
Spiked Carapace stun can be instantly dispelled by Aphotic Shield.
* Abaddon can use Borrowed Time and easily heal for the duration of Borrowed Time by Nyx's burst damage.
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.
Abaddon
* Heroes that deal damage over time will also fail to bring down Abaddon and his allies, such as Huskar, Venomancer, or Phoenix.
Additional:
* Borrowed Time & Aphotic Shield can dispel Venomous Gale and Poison Sting.
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.
Abaddon
* 
Sticky Napalm, Flaming Lasso, and Flamebreak can all be instantly dispelled by Aphotic Shield.
* Firefly will continuously heal Abaddon under Borrowed Time.
Additional:
* Aphotic Shield and Borrowed Time can both dispel Flaming Lasso.
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
* Attacks from Boars and the attack speed boost from Inner Beast will quickly wear down Refraction.
Abaddon
* 
Primal Roar can be instantly dispelled by Aphotic Shield.
* The debuffs from 
Wild Axes and 
Poison from 
Call of the Wild: Boar can also be dispelled by Aphotic Shield.
Additional:
* Aphotic Shield effectively nullifies Primal Roar's single-target initiation on allies.
* Even being initiated by Primal Roar, Borrowed Time can make Abaddon extremely difficult to kill.
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.
Abaddon
* Abaddon could punish Chaos Knight for using his Phantasm and Reality Rift combo on him with Aphotic Shield. Additionally, it provides extra protection against Chaos Knight's potential to take Abaddon down quickly.
* Furthermore, Abaddon's Borrowed Time makes it utterly impossible to burst Abaddon down, effectively reducing the amount of targets Chaos Knight can threaten by 1 for the entire game.
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
* 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
* 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.
Abaddon
* Aphotic Shield is a strong dispel, meaning it can save allies from Earth Spirit's stun, slow, silence, and Magnetize.
* Borrowed Time makes it nearly impossible for Earth Spirit to kill Abaddon.
Abaddon
* Mana Break drains Abaddon's mana, preventing him from using Aphotic Shield to zone out enemies in lane.
* Counterspell decreases the amount of damage received from Aphotic Shield and Mist Coil.
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.
Abaddon
* Heroes that have long silences, such as Night Stalker and Silencer, will prevent Abaddon from saving his allies effectively and disable the active component of Borrowed 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
Abaddon
* 
Astral Imprisonment wastes Borrowed Time's duration.
* Outworld Destroyer's 
Sanity's Eclipse can kill Abaddon before Borrowed Time triggers due to the lack of intelligence for Abaddon.
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
*
Bushwhack can tear through 
Refraction as it does multiple intervals of damage.
Abaddon
* Abaddon can be killed without triggering his ultimate
Borrowed Time due to the break applied by 
Sharpshooter.
