Templar Assassin
* 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.
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.
Shadow Demon
* Icarus Dive quickly escapes from Shadow Demon abilities, especially 
Demonic Purge.
* Phoenix AoE abilities remove Shadow Demon's illusions created by 
Disruption.
Templar Assassin
* 
Pulse Nova can easily burn Templar Assassin's Refraction charges quickly, and can also hit her with her Meld.
Shadow Demon
* Diabolic Edict and Pulse Nova will tear apart any illusions spawned from Disruption
* Split Earth can punish improper usage of Disruption.
* Leshrac does not have any buffs that can be removed by Demonic Purge.
Additional:
* Pulse Nova makes quick work of any illusions with amplified damage, and deals damage even if Leshrac is in Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Split Earth for the enemy.
* Disruption does not stop 
Diabolic Edict and Pulse Nova once they start pulsing, and even worse it provides a safe shelter for Leshrac to keep pumping up his powerful AoE damage onto the battlefield.
* Shadow Demon doesn't have the burst damage to take Leshrac out of the fight quickly, although Demonic Purge can help his allies kill a squishy Leshrac.
Templar Assassin
* Ember Spirit burns quickly Refraction thanks to its own 
Flame Guard, which is why it can interrupt Templar Assassin, giving its team the opportunity to quickly kill her
* Ember Spirit dodges a blow from Meld his own 
Sleight of fist, which can be a big problem for her in a 1-on- 1 fight
* 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:
* 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
Shadow Demon
* Disruption is not reliable enough to catch an Ember Spirit with a backup 
Fire Remnant.
* Sleight of Fist will also make quick work of the spawned illusions.
* The best you can do against an Ember Spirit is to dispel his Flame Guard with your Demonic Purge.
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.
Shadow Demon
* 
Chaos Knight, 
Lone Druid, 
Meepo and 
Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
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
Shadow Demon
* All of Queen of Pain's abilities are active, making Demonic Purge break from 
Aghanim's Scepter useless.
* However, Demonic Purge can help his allies kill a squishy Queen of Pain.
* 
Blink allows Queen of Pain to escape from Shadow Demon's abilities if he doesn't have disables.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Sonic Wave for the enemy.
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
Shadow Demon
* Chaos Knight, Lone Druid, Meepo and Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
Additional:
* Poof will destroy Shadow Demon's illusions created by Disruption and quickly escapes from 
Shadow Poison & Demonic Purge.
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.
Shadow Demon
* Chaos Knight, Lone Druid, Meepo and Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
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
Shadow Demon
* Lycan and 
Weaver has abilities that allow them to move at maximum movement speed, and those abilities can't be dispelled, potentially wasting the slow from Demonic Purge.
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.
Shadow Demon
* Chaos Knight, Lone Druid, Meepo and Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
Shadow Demon
* Heroes with summons or illusions can counter Flux, such as 
Beastmaster , 
Chen, or 
Shadow Demon.
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
Shadow Demon
* 
Death Ward with Aghanim's Scepter makes quick work of the spawned illusions from Disruption.
* However, it can be cancelled by Disruption until Witch Doctor buys 
Linken's Sphere or Black King Bar.
* All of Witch Doctor's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* 
Voodoo Restoration can out-heal the damage from Shadow Demon's abilities.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Maledict or 
Paralyzing Cask for the enemy.
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
* Phantom Lancer's illusions destroy Refraction charges very quickly.
Shadow Demon
* Although Phantom Lancer will generate strong illusions, and you can also break his 
Juxtapose with an Aghanim's Demonic Purge, you have a small chance of guessing which is the real Phantom Lancer after he uses 
Doppelganger.
Shadow Demon
* Shadow Demon's Demonic Purge is undispellable.
* Heroes with undispellable debuffs will help identify the real Phantom Lancer through visual effects or debuff indicators, provided that it was cast on the real Phantom Lancer to begin with:
* Doom's 
Doom marks Phantom Lancer with a highly visible effect, and also silences and mutes him.
* 
Bloodseeker's 
Rupture shows a clear red trail effect on the real Phantom Lancer.
* Ancient Apparition's 
Ice Blast will only debuff Phantom Lancer and not his illusions.
* Grimstroke's 
Soulbind is undispellable.
* Shadow Demon's Demonic Purge is undispellable.
* 
Monkey King's 
Jingu Mastery is undispellable and puts a big yellow Mark over his head.
Additional:
* Phantom Lancer's strength is the sheer amount of illusions he can conjure, Dissimulate can be cast on an ally that he is focusing to quickly thin out his ranks
* Landing a upgraded Demonic Purge on the real Phantom Lancer prevents him from making very many illusions (His only source being Doppelganger), You can reapply as needed if you have the Shard
* Disrupting Phantom Lancer allows you to create multiple extra illusions with Juxtapose, As he is a common carrier of 
Diffusal Blade, you can also drain the mana of any nearby heros
Templar Assassin
* Shackles and Mass Serpent Ward instantly destroy Refraction
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
* The damage block instances of Refraction can be burned down with Ignite.
* Fire Shield effectively reduces the burst damage from a Meld-charged ambush from Templar Assassin, provided the spell is cast beforehand.
Templar Assassin
* 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.
Templar Assassin
* The three Primal Split brewlings all attacking Templar Assassin at once will remove her Refraction quickly, especially with Fire's Permanent Immolation.
* Templar Assassin has no way to stop Brewmaster from using Primal Split by herself, and may get unlucky and miss her Meld if trying to burst him during her ally's disable.
Templar Assassin
* 
Bushwhack can tear through Refraction as it does multiple intervals of damage.
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.
Shadow Demon
* All of Lion's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* 
Hex and 
Mana Drain can make quick work of whatever illusions you're creating, especially when he acquires his Talents at level 20 and 25.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Earth Spike or 
Finger of Death with Aghanim's Scepter for the enemy.
Templar Assassin
* Attacks from Boars and the attack speed boost from Inner Beast will quickly wear down Refraction.
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.
* 
Flaming Lasso pierces Black King Bar and rendering Templar Assassin helpless unless there are allies helping her.
Additional:
* Batrider's DoT damage quickly removes Templar Assassin's Refraction and can damage her during Meld.
Shadow Demon
* For the same reason, he has to be slightly more cunning when playing against heroes that can scout the treeline, such as Ancient Apparition and his 
Ice Vortex and Shadow Demon and his Shadow Poison.
Shadow Demon
* Shadow Demon, 
Outworld Destroyer and 
Tusk can all save a Lasso'd teammate with their defensive spells.
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
* 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.
Additional:
* 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
* 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
* 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
* 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
* 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.
Shadow Demon
* You can potentially kill a fragile Weaver by using Disruption during 
Shukuchi with a well-placed 
Sentry Ward, wasting the Shukuchi. But odds are he'll wait to get low health, 
Time Lapse the damage away and Shukuchi away once more.
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.
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.
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
* 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.
Shadow Demon
* All of Puck's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Shadow Demon will find a hard time catching a Puck, as he can get away with 
Illusory Orb or even 
Waning Rift;
* Puck can dodge Shadow Poison waves and potentially avoid the damage from Demonic Purge with 
Phase Shift. Furthermore, after Disruption ended, Puck can use Phase Shift to avoid any further danger and can blink away with Blink Dagger.
* Waning Rift can be used to initiate Shadow Demon, prevent him from using any spells.
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
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, Warlock.
Templar Assassin
* Templar Assassin's Refraction will easily be removed by Eye of the Storm, and Static Link reveals Templar Assassin hiding with Meld and drain the bonus damage from Refraction.
Additional:
* Razor's 
Eye of the Storm damage-over-time easily wear off Refraction charges, allowing Templar Assassin to be damaged.
* 
Static Link empties Templar Assassin's damage output even with the bonus from Refraction, and will keep doing that even if the Razor cannot see her during Meld.
* 
Plasma Field can easily strike her during Meld.
Shadow Demon
* Squishy heroes or heroes without hard disables or silences: Shadow Demon, 
Shadow Fiend, 
Venomancer, Ancient Apparition etc.
Additional:
* Shadow Demon will have a hard time catching Storm Spirit, as he can get away with 
Ball Lightning.
* 
Static Remnant will make quick work of the spawned illusions from Disruption.
* With very high mobility and usually being paired with Orchid Malevolence, he can catch Shadow Demon with ease both in ganks and in teamfights if Shadow Demon has no survivability items.
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
Shadow Demon
* Shadow Demon's Demonic Purge with Aghanim's Scepter cannot break 
Reincarnation, which could put him in a disadvantage against Wraith King if his whole team is with him.
* 
Vampiric Spirit can out-heal the damage from Shadow Demon's abilities.
* However, Wraith King is a single-target hero, so he cannot deal with Disruption illusions.
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
* 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
Shadow Demon
* Shadow Demon's main source of damage is his low cooldown, high damage spells - meaning Last Word and Global Silence will pretty much take him out of the game for the duration.
* Shadow Demon likes to spam his abilities, which makes him vulnerable to Arcane Curse.
* If Shadow Demon dies near Silencer, he will lose intelligence, reducing his mana pool, mana regen, and attack damage. Furthermore, if the game is long and Shadow Demon dies often, the intelligence losses will also reduce his spell damage.
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
* 
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.
Shadow Demon
* Heroes with abilities that can save teammates are also effective such as Shadow Demon, 
Dazzle, 
Oracle, 
Bane, Pugna, Tusk, 
Winter Wyvern, 
Io, 
Underlord, Treant Protector and 
Keeper of the Light.
Additional:
* Be ready to save an ally from Omnislash with your Disruption.
* Spawning 
Juggernaut's illusions is a great deal, as his base attack time is low and he has a critical strike. Illusions will benefit from both.
* Demonic Purge will prevent Juggernaut's desperate attempt to flee using Blade Fury. However, it cannot stop him if he is using 
Town Portal Scroll.
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
* 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
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
* 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.
Additional:
* 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.
Shadow Demon
* Heroes that lose a great amount of their tankiness and become easier to finish off: 
Bristleback, 
Spectre, Phantom Assassin, 
Enchantress, 
Dragon Knight.
* Once you have an Aghanim's Scepter, Shadow Demon instantly reaches a new power spike and becomes a counter for a variety of heroes that have strong passives.
* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, Spectre, Phantom Assassin, Enchantress, Dragon Knight.
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
Templar Assassin
* Refraction can be very useful in safely neutralizing Proximity Mine fields, or absorbing Techies' Blast Off combo.
Shadow Demon
* Shadow Demon's spammable illusions can be used to scout Techies' 
Proximity Mines. The illusion of your carries can be even used to trick Techies into detonating his precious 
Remote Mines.
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.
Shadow Demon
* Disruption sets up Anti-Mage for a chain disable. The illusions will deal extra damage due to Mana Break.
* Shadow Poison hits Anti-Mage even after he's Blinked away.
* If Shadow Demon has Aghanim's Scepter, Demonic Purge can break Mana Break and Counterspell, weakening both his offense and defense.
Additional:
* While it is unwise to encounter Anti-Mage alone, Disruption's considerable cast range can become a perfect setup for any hard-disable to follow up. If he is pinned down, Anti-Mage will quickly face his demise when the illusions deplete his already low mana pool. Manta Style will easily allow him to escape, however.
* The illusions can be controlled to quickly sap mana from any other target, making Anti-Mage one of the most valuable targets to disrupt.
Templar Assassin
* Sven has no easy way to burn Refraction charges and needs help from teammates to kill TA successfully.
Shadow Demon
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* Once you have an Aghanim's Scepter, Shadow Demon instantly reaches a new power spike and becomes a counter for a variety of heroes that have strong passives.
* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, Spectre, Phantom Assassin, Enchantress, Dragon Knight.
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
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.
Shadow Demon
* Shadow Demon's Demonic Purge renders Ursa useless even through Black King Bar as it slows him, continually purges his Overpower charges and can not be dispelled by Ursa's Enrage.
* Disruption is a good way to save teammates against Ursa. Disrupting Ursa is also a good way to kite him, as it can not be dispelled by Enrage.
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.
Shadow Demon
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: Sniper, Shadow Fiend, 
Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
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
Shadow Demon
* Disruption instantly removes Phantom Embrace, and can potentially save allies affected by Soulbind.
* Demonic Purge dispels Ink Swell.
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
Additional:
* 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.
Shadow Demon
* Shadow Demon's Disruption will allow his allies to maneuver around you. It can also be used to protect an ally from your abilities, or Astral Imprisonment - 
Meteor Hammer combo.
* 
Disseminate turns your high damage Arcane Orb and Sanitiy's Eclipse against you and your teammates.
* Scepter upgraded Demonic Purge will break your Essence Flux passive for 7 seconds, preventing you from regaining mana, and severely hindering your damage output.
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.
Shadow Demon
* Disruption can protect Shadow Demon's allies from Fortune's End, preserving healing or buffs. It can also catch Oracle's allies, allowing Shadow Poison to be used without being dispelled.
* Demonic Purge prevents over-time healing during False Promise, such as Purifying Flames and 
Urn of Shadows. If he has Aghanim's Scepter, this issue can persist for longer or on multiple allies.

Mekansm a good choice against him.
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
Shadow Demon
* Doom, 
Disruptor with Aghanim's Scepter, Dazzle with Aghanim's Shard, and hex abilities all prevent item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. Doom and Shadow Demon with Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility.
Templar Assassin
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz
Shadow Demon
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: Sniper, Shadow Fiend, Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.

Reactive Armor, which will allow the team to kill Timbersaw quickly, or drive him out of the fight.

Whirling Death, which will give her the ability to deal Timbersaw more damage than he will deal.

Shadow Demon
* Alchemist is a well-known 
Radiance carrier among other auras your illusions will benefit from. They also get the extra move speed and reduced base attack time from his 
Chemical Rage, and it's even better if you can catch him as his own rage is about to expire.
* Disruption will buy enough time for all allies to retreat when Alchemist starts to activate 
Unstable Concoction.
Shadow Demon
* Disruption can save allies and mess up an initiation from an enemy Legion Commander. Using Disruption on your ally that is affected by 
Duel will leave her totally exposed without the benefit of the life steal from

Press the Attack, which in turn can be dispelled by your ultimate.
Templar Assassin
* Refraction negates all of Void Spirit's burst damage.
* Meld quickly burns through 
Resonant Pulse.
Shadow Demon
* Disruption will save Shadow Demon's teammates from being killed by Counter Helix or Culling Blade.

* 
Demonic Cleanse clears Battle Hunger and Aghanim's Shard Counter Helix Damage Reduction, both allowing targets to escape and reducing your own survivability.
Additional:
* While it is unwise to encounter Axe alone, Disruption can be used to save your allies from Axe's initiate 
Berserker's Call, or, if timed correctly, from his 
Culling Blade.
* Illusions spawned from Axe has the Counter Helix passive, which with deal some nasty damage if an enemy focuses them
* Your upgraded Demonic Purge breaks Axe's primary damage output: 
Counter Helix, This can be used on him during Berserker's Call to seriously hinder him.
* Demonic Cleanse will clear 
Battle Hunger, which is Axe's method of catching heroes, and Shard upgraded Counter Helix's Damage Reduction, which is one of Axe's primary survivability abilities.
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.
Shadow Demon
* Disruption can banish Faceless Void or an ally in Chronosphere, making it a less effective ability.
* Faceless Void's illusions created by Disruption will not get stunned by Chronosphere, allowing Shadow Demon to attack Faceless Void in his Chronosphere.
* Casting Disruption after releasing Shadow Poison charges will make Time Walk unable to backtrack the damage.
* Shadow Poison is a good way to deal damage as the initial damage and the release damage can't both be Time Walked at the same time.
* Demonic Purge is a great slow, useful to force out a Time Walk early and can break Time Lock with Aghanim's Scepter.
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.

Shadow Demon
* Disruption can save an ally from a fatal Reaper's Scythe.
* Demonic Purge can remove Ghost Shroud, making Necrophos vulnerable to physical damage and preventing him from regenerating health.
Shadow Demon
* Her illusions with 
Desolate are very valuable, especially when they are usually paired with Radiance. Unlike blink or force movement, 
Spectral Dagger's escaping mechanic requires manual movement, and therefore Demonic Purge can hold her back really hard and allow your allies to finish her off.
* If she tries to kill you or any key ally with 
Haunt at any point of the game, remember to not panic and always use Disruption on the illusion, whether it is fake or the real Spectre herself. When the situation calls, Demonic Purge can save a second victim from a haunting Spectre.
* When upgraded by Aghanim's Scepter, Demonic Purge can remove Spectre from a fight by disabling Desolate and 
Dispersion, negating her damage and tankiness respectively.
Shadow Demon
* 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.
Shadow Demon
* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper, Shadow Shaman with Hex Breaks talent.

Phoenix with Aghanim's Scepter.

Batrider.
Shadow Demon

Death Prophet.
Templar Assassin
* 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.
Additional:
* 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.
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.
Shadow Demon
* In the laning stage, making illusions of Venomancer will turn his Poison Sting back at him, making for an easy gank at level one, and for later when your mid comes for ganks.
Templar Assassin
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz
Shadow Demon

* Similarly, they can negate your X Marks The Spot & Torrent combo by protecting your target when you use Return. Good candidates to negate your combo include Outworld Destroyer and his Astral Imprisonment, and Shadow Demon and his Disruption.
* A 
Eul's Scepter of Divinity can also do the trick, but, unlike the previously mentioned abilities, you can only use it on yourself and not your allies.
Shadow Demon
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, 
Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden).
Shadow Demon
* Demonic Purge takes off Luna's superior mobility, removing the need for chasing her and allowing your team to reposition in team fights or escape when at low HP. If Shadow Demon has Aghanim's Scepter it will also take away glaive bounces and extra damage from Luna's passive.
* Luna's illusions created by Disruption are very valuable with their 
Moon Glaives. These will effectively counter her pushing attempts and are painfully effective in team fights.
* Disruption can be used to save an ally from 
Eclipse.
* For the same reasons, Shadow Demon makes a very powerful ally for Luna when they are in the same team.

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.
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.
* Templar Assassin usually buys Blink Dagger, enabling her to quickly close the gap to Zeus' defensive positioning.
Additional:
* 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.
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.
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.

Broodmother, Lycan, Enigma, Chaos Knight, Phantom Lancer, Shadow Demon, 
Dark Seer, Nature's Prophet, Invoker, Morphling, Visage, Grimstroke with Aghanim's Scepter.
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 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
* 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
* Ion Shell destroys Refraction's protection stacks in short time.
* Surge ignores the massive slow from Psionic Trap.
Shadow Demon
* The constant dispel from Demonic Purge will make any attempt to save the victim or himself by 
Surge become futile. For what it's worth, Demonic Purge will also dispel 
Ion Shell.
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.

Additional:
* Dark Pact rips through Refraction charges and still steals attributes during Refraction.

* 
Dragon Slave will make quick work of the spawned illusions from Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Light Strike Array for the enemy.
* Shadow Demon doesn't have the burst damage to take Lina out of the fight quickly, although Demonic Purge can help his allies kill a squishy Lina.
Templar Assassin
* Outlanes Lina on the center line thanks to her own Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her
* Closes from Lina's magic attacks with her own Refraction, which is why Lina can't make her combination: Light Strike Array, Dragon Slave, 
Laguna Blade and kill Templar Assassin quickly

Templar Assassin
* 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...
Shadow Demon
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, Shadow Demon and 
Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
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.

Omniknight, 
Dawnbreaker.

Magnus, Dragon Knight, Luna, 
Medusa, Templar Assassin, Gyrocopter, 
Muerta.
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.
Shadow Demon

* However note that Shadow Demon is a squishy target and you can often overwhelm him if he is alone, But he can still Disrupt you to escape
Additional:
* Shadow Poison can quickly stack up on Huskar, And with his naturally low health you don't need as many stacks to be effective.
* Disruption turns Huskars high attack speed against him, They also have the highest survivability as illusions due to his passive 
Berserker's Blood, It also allows you to put Shadow Poison stacks on him,
* Dissimulate turns Huskar's burning damage against his team, You can cast it on an ally who is taking a bunch of Burning Spear stacks and cause Huskar to take high amounts of damage as well
* Scepter upgraded Demonic Purge is your most effective weapon against him, It's 7 second Break causes him to quickly die in battle
Templar Assassin
* Pugna's
Decrepify can render Templar Assassin's physical attacks useless.
Life Drain on Templar Assassin, burning her Refraction instances.
* Pugna can also cast

Aghanim's Scepter useless.
Nether Ward punishes Shadow Demon's constant mana usage from spamming spells, especially Shadow Poison.
Nether Blast for the enemy.
Life Drain can be used to heal Pugna or an ally to save them from Shadow Demon's abilities.
