Razor
[wiki] rating: 2.0 (winrate: 49% pickrate: 1%)Phantom Lancer
[wiki] rating: 2.0 (winrate: 47% pickrate: 5%)Templar Assassin
* Phantom Lancer's illusions destroy 
Refraction charges very quickly.
Tusk
* 
Doppelganger allows Phantom Lancer to dodge an incoming snowball.
* Phantom Lancer usually buys a 
Diffusal Blade, which is very effective against Tusk's low mana pool.
* Phantom Lancer usually buys 
Manta Style which can also dodge an incoming snowball, much like Doppelganger.
Earth Spirit
[wiki] rating: 1.6 (winrate: 49% pickrate: 7%)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:
* 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.
Tusk
* 
Boulder Smash can return Tusk after his initiation.
* 
Geomagnetic Grip prevents Tusk from using Snowball to escape.
Dragon Knight
[wiki] rating: 1.6 (winrate: 47% pickrate: 2%)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.
Tusk
* Durable heroes can fight with stand against Tusk during 1v1: 
Axe, 
Dragon Knight, 
Night Stalker, 
Centaur Warrunner, 
Wraith King and more.
Slark
[wiki] rating: 1.2 (winrate: 47% pickrate: 13%)Templar Assassin
* Weak damage but high tick rate or persist in a long time: 
Slark, 
Gyrocopter, 
Queen of Pain, 
Shadow Shaman (
Shackles), 
Pugna
* 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), Pugna
Additional:
* 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.
Tusk
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: 
Anti-Mage, Earth Spirit, 
Faceless Void, 
Magnus, 
Mirana, 
Monkey King, 
Morphling, 
Pangolier, 
Phantom Assassin, 
Phoenix, 
Puck, Queen of Pain, Riki, 
Sand King, Spirit Breaker, 
Timbersaw, Tusk.
Dark Seer
[wiki] rating: 1.0 (winrate: 53% pickrate: 5%)Templar Assassin
* Ion Shell destroys Refraction's protection stacks in short time.
* Surge ignores the massive slow from 
Psionic Trap.
Arc Warden
[wiki] rating: 1.0 (winrate: 52% pickrate: 9%)Templar Assassin
* Arc Warden's 
Flux tears through Refraction charges almost instantly. Should he have a 
Tempest Double and no creeps are around, a 75% slow means almost certain death.
* Meld is useless against 
Spark Wraith.
Additional:
* Flux wastes Templar Assassin's Refraction unless she has a 
Black King Bar or a Manta Style.
* Spark Wraith can be used to bully a Templar Assassin that used Meld.
Ogre Magi
[wiki] rating: 1.0 (winrate: 51% pickrate: 16%)Templar Assassin
* The damage block instances of Refraction can be burned down with Ignite.
Beastmaster
[wiki] rating: 1.0 (winrate: 51% pickrate: 2%)Templar Assassin
* Attacks from Boars and Inner Beast will quickly wear down Refraction.
* 
True Sight provided by Level 3 
Necronomicon can see Templar Assassin in Meld.
Sand King
[wiki] rating: 1.0 (winrate: 51% pickrate: 7%)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.
Huskar
[wiki] rating: 1.0 (winrate: 50% pickrate: 3%)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 being ganked or harassed, and in turn forcing her out of the lane.
Windranger
[wiki] rating: 1.0 (winrate: 50% pickrate: 24%)Templar Assassin
* Windranger's 
Focus Fire tears apart Templar Assassin's refraction very quickly and easily bursts here 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
Shadow Shaman
[wiki] rating: 1.0 (winrate: 50% pickrate: 6%)Templar Assassin
* Shackles and Mass Serpent Ward instantly destroy Refraction
Jakiro
[wiki] rating: 1.0 (winrate: 50% pickrate: 14%)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.
Phoenix
[wiki] rating: 1.0 (winrate: 49% pickrate: 13%)Templar Assassin
* 
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 make a safe distance before she even landed the hit.
* 
Sun Ray has 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.
Additional:
* 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.
Brewmaster
[wiki] rating: 1.0 (winrate: 48% pickrate: 2%)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.
Pudge
[wiki] rating: 1.0 (winrate: 48% pickrate: 24%)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.
Riki
[wiki] rating: 0.6 (winrate: 53% pickrate: 5%)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.
Night Stalker
[wiki] rating: 0.6 (winrate: 52% pickrate: 6%)Tusk
* Durable heroes can fight with stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Slardar
[wiki] rating: 0.6 (winrate: 51% pickrate: 9%)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.
Lycan
[wiki] rating: 0.6 (winrate: 50% pickrate: 1%)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

Spirit Breaker
[wiki] rating: 0.6 (winrate: 50% pickrate: 6%)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.
Bounty Hunter
[wiki] rating: 0.6 (winrate: 50% pickrate: 5%)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.
Chaos Knight
[wiki] rating: 0.6 (winrate: 50% pickrate: 3%)Templar Assassin
* 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.

Axe
[wiki] rating: 0.6 (winrate: 49% pickrate: 10%)Tusk
* Durable heroes can fight with stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Leshrac
[wiki] rating: 0.6 (winrate: 49% pickrate: 2%)Templar Assassin
* Heroes that have disposable area-targeted spells can force her to undo her Meld: 
Leshrac, Puck, 
Tiny. An experienced Templar Assassin could try to Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Naga Siren
[wiki] rating: 0.6 (winrate: 48% pickrate: 2%)Templar Assassin
* 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.

* 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), Pugna
Additional:
* Ensnare disables Lanaya's invisibility and Blink Dagger (a core item on Templar Assassin), and her illusions will break Refraction easily.

Juggernaut
[wiki] rating: 0.4 (winrate: 51% pickrate: 19%)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.
Tusk
* Heroes with abilities that can save are also effective such as 
Shadow Demon, 
Dazzle, 
Oracle, 
Bane, Pugna, Tusk, 
Winter Wyvern, 
Io, 
Underlord, Treant Protector and 
Keeper of the Light.
Disruptor

Batrider
[wiki] rating: 0.4 (winrate: 46% pickrate: 3%)Templar Assassin
* 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.
Additional:
* Batrider's DoT damage quickly removes Templar Assassin's Refraction and can damage her during Meld.
Tusk
* Shadow Demon, 
Outworld Devourer and Tusk can all save a Lasso'd teammate with their defensive spells.
Shadow Fiend
[wiki] rating: -2.0 (winrate: 48% pickrate: 11%)Tusk
* Shadow Fiend is lack of mobility and low base health, make him a prime target for early ganks.
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.
Sniper
[wiki] rating: -1.6 (winrate: 46% pickrate: 6%)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 Devourer Zeus
Tusk
* Snowball allows Tusk to move himself and allies towards Sniper whilst invulnerable and hidden.
* His 
Ice Shards may also block pathing for Sniper as he has no means of moving through obstacles. In addition, 
Tag Team can hinder Sniper's escape.

* Tusk alone or with his teammates can close Sniper's long range easily with Snowball, even wasting Sharpenel, ending with a very vulnerable Sniper.
* Warlus Punch damage can easily kill Sniper's low health instantly.
Drow Ranger
[wiki] rating: -1.6 (winrate: 53% pickrate: 13%)Templar Assassin
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, 
Drow Ranger, 
Clinkz
Tusk
* Snowball and Ice Shards keep Drow Ranger down and preventing her from running away.
* Snowball also lets Tusk get to Drow Ranger and stop her Marksmanship bonus. It can also be to save allies affected by Gust.

Puck
[wiki] rating: -1.0 (winrate: 47% pickrate: 6%)Templar Assassin

Omniknight, 
Huskar , and Tusk have spells which allow them to easily escape Dream Coil.
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.
Invoker
[wiki] rating: -1.0 (winrate: 49% pickrate: 21%)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.
Legion Commander
[wiki] rating: -1.0 (winrate: 50% pickrate: 14%)Tusk
* Walrus PUNCH! makes Legion Commander lose 
Duel easily, especially when she doesn't have

* Walrus PUNCH! can be used to cancel 
Fiend's Grip if he is not a target.
Zeus
[wiki] rating: -1.0 (winrate: 53% pickrate: 14%)Templar Assassin
* Heroes that avoid damage by coming in and out of invisibility in teamfights such as 
Weaver, Templar Assassin, and Riki will be easy for Zeus to reveal with Lightning Bolt and Thundergod's Wrath, but these heroes usually have other ways to avoid his damage or kill him, so he is not a perfect counter alone.
Tusk
* Heroes with long range abilities are also able to touch Zeus, such as 
Clockwerk, 
Kunkka, Puck, 
Skywrath Mage, Spirit Breaker, Tusk and others.
Templar Assassin
* 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.

Grimstroke
[wiki] rating: -0.6 (winrate: 45% pickrate: 10%)Templar Assassin

Ancient Apparition, 
Grimstroke, Witch Doctor
Outworld Devourer
[wiki] rating: -0.6 (winrate: 47% pickrate: 3%)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 Devourer Zeus
Additional:
* Refraction blocks most of the damage dealt with Arcane Orb and Sanity's Eclipse if used correctly, and is difficult for Outworld Devourer to deal with.
* If Astral Imprisonment is on cooldown, then an Outworld Devourer slowed by Psionic Trap is an easy kill for Templar Assassin, especially during the laning stage.
Lifestealer
[wiki] rating: -0.6 (winrate: 47% pickrate: 8%)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
Tiny
[wiki] rating: -0.6 (winrate: 47% pickrate: 17%)Templar Assassin
* Heroes that have disposable area-targeted spells can force her to undo her Meld: Leshrac, Puck, Tiny. An experienced Templar Assassin could try to Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Tusk
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Templar Assassin
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Phantom Assassin, Templar Assassin, Ursa, Wraith King etc).
Ursa
[wiki] rating: -0.6 (winrate: 48% pickrate: 6%)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
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, Templar Assassin, 
Arc Warden

* Snowball help Tusk and his allies follow a fleeing Pangolier, keep in mind that the Pangolier can always counter-initiate with his Rolling Thunder.
* Walrus PUNCH! deals heavy damage even during his Rolling Thunder.
Silencer
[wiki] rating: -0.6 (winrate: 48% pickrate: 6%)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
Ancient Apparition
[wiki] rating: -0.6 (winrate: 49% pickrate: 7%)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 Devourer Zeus
Oracle
[wiki] rating: -0.6 (winrate: 51% pickrate: 8%)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.
Crystal Maiden
[wiki] rating: -0.6 (winrate: 51% pickrate: 13%)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.
* 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
Tusk
* Snowball allows Tusk to easily cancel Freezing Field from a safe distance without putting himself in any danger.
* Walrus PUNCH! is most certainly a high enough damage nuke to easily kill off Crystal Maiden.
* Ice Shards can prevent the already immobile Crystal Maiden from escaping, making her an easy kill for either Tusk or a teammate.
Additional:
* Crystal Maiden's low health and armor makes her an easy target for Warlus Punch.
* Tusk's Snowball can protect allies and cancel 
Freezing Field.
* Snowball and Walrus PUNCH! can interrupt Freezing Field.

* Durable heroes can fight with stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
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.
Enigma
[wiki] rating: -0.4 (winrate: 51% pickrate: 3%)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), Pugna
Tusk
* Walrus PUNCH! interrupts Black Hole and it pierces spell immunity.
Bloodseeker
[wiki] rating: -0.4 (winrate: 52% pickrate: 6%)Templar Assassin

Witch Doctor
[wiki] rating: 0.0 (winrate: 48% pickrate: 13%)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), Pugna
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
Techies
[wiki] rating: 0.0 (winrate: 48% pickrate: 7%)Tusk
* After using Snowball, Tusk can't control where he's going, allowing Techies to make him roll into mines.
Templar Assassin
* Refraction can be very useful in safely navigating potentially mined choke points and rune spawns.
Earthshaker
[wiki] rating: 0.0 (winrate: 49% pickrate: 12%)Tusk
* 
Echo Slam is good against Snowball since it bunches everyone up. This can set up some prime opportunities for blink echo slams.
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.
Viper
[wiki] rating: 0.0 (winrate: 50% pickrate: 5%)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 over time 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 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.
Tusk
* Viper Strike can be countered through Snowball, wasting Viper's mana through his ultimate.
Pugna
[wiki] rating: 0.0 (winrate: 50% pickrate: 6%)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.
Tusk
* Pugna's low health and reliance on channeled abilities make him very vulnerable to Tusk, although Pugna can win in a straight up 1v1 later in the game.
Warlock
[wiki] rating: 0.0 (winrate: 51% pickrate: 8%)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 escape.
* Warlock can also send his {U:Warlock Golem} near where she used Meld, preventing escape by Blink Dagger due to the {U:Warlock Golem} 
Permanent Immolation.
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
Anti-Mage
[wiki] rating: 0.0 (winrate: 51% pickrate: 16%)Tusk
* 
Mana Break is very effective against Tusk, as he has a very low mana pool.
* 
Blink allows Anti-Mage to escape from an incoming Snowball.
* 
Counterspell reflects the Snowball back onto Tusk
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.
Wraith King
[wiki] rating: 0.0 (winrate: 51% pickrate: 8%)Tusk
* Durable heroes can fight with stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
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
Venomancer
[wiki] rating: 0.0 (winrate: 52% pickrate: 12%)Templar Assassin
* Windranger's Focus Fire tears apart Templar Assassin's refraction very quickly and easily bursts here 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
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.
Tusk
* Snowball can be used to save allies or him during 
Venomous Gale and 
Poison Nova.
* Venomancer has lack of mobility and low base health can killed by Warlus Punch.
Templar Assassin
* 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 and 
Storm Surge can easily strike her during Meld.

Tusk
*
Static Link drains Tusk base damage it also reduces his Warlus Punch crit.
Plasma Field and 
Eye of the Storm allows to chase Tusk after using his Snowball.
