* Witch Doctor's Maledict burst damage can be prevented by Sunder, if timed correctly.
* Death Ward deals physical damage, and Terrorblade's high armor can help him survive against Death Ward.
* However, be careful that Paralyzing Cask is commonly tricky to dodge as Terrorblade, due to his reliance of illusions, and Maledict can kill Terrorblade if he has no target to be Sundered with, especially in the early game.

* Vengeful Spirit has two abilities to interrupt Death Ward, even through Black King Bar.

* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit

* Sunder can save himself or his allies from Assassinate.
* Sniper relies on right-clicks to deal damage, and Terrorblade's high armor can reduce his damage by quite a bit.
* Terrorblade is a far harder carry than Sniper is, so a well-farmed Terrorblade can easily defeat a Sniper.

* Terrorblade's illusions and ranged attacks in Metamorphosis can burst down Lifestealer very quickly.
* Terrorblade has low health due to his low strength gain, which reduces Feast's lifesteal and damage.
* Terrorblade's high armor makes Lifestealer's Desolator useless.
* Because Lifestealer usually walks around with high HP in fights due to his lifesteal (and sometimes Armlet of Mordiggian), he is a great target for Terrorblade's Sunder.
Additional:
* Reflection's illusion carries Feast as well, making it useful in fights.
* Open Wounds is a lot harder to land on the real Terrorblade if he has illusions around him.
* Lifestealer relies on right-clicks to deal damage, and Terrorblade's high armor can reduce his damage by quite a bit.

* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.

* Sunder can prevent Terrorblade's or an ally's death by swapping health, making damage-over-time spells inefficient. Heroes that rely on damage-over-time abilities like Venomancer and Huskar will have a hard time against Sunder.

* Huskar struggles against heroes that output high physical damage due to his low armor. Vengeful Spirit's Wave of Terror and Vengeance Aura help increase the physical damage of her team.

* Vengeful Spirit can Nether Swap enemies out of Power Cogs.

Additional:
* Nether Swap gives Vengeful Spirit a way to save an ally from Clockwerk's Power Cogs.
* Magic Missile will interrupt Clockwerk trying to run down Vengeful Spirit's allies with Battery Assault.

* Conjure Image and Reflection illusions may give Clockwerk a hard time to find an angle for Hookshot.
* A trapped Terrorblade can turn the tables with Sunder, leaving Clockwerk nowhere to run.

* Terrorblade is one of the strongest carries in the late game, due to his resilience against physical damage, which can be a problem for almost every strong burst physical damage carries, such as Phantom Assassin and Templar Assassin.

* Heroes with disables that ignore spell immunity will render Phantom Assassin quite useless in teamfights throughout the game: Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge.

* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.

* Illusion-based heroes are effective against Omnislash and Juggernaut's single-targeted damage: Naga Siren, Chaos Knight, Terrorblade,Phantom Lancer.

* Wraith King has no form of AoE to clear Terrorblade's illusions.
* Terrorblade is a common Manta Style and Diffusal Blade carrier.
* Terrorblade has very high armor, which helps against Wraith King's physical-only damage.
* A reincarnated Wraith King is an ideal target for Sunder if Terrorblade's health is low.

* Pudge has low armor and low mobility, making him a prime target for Terrorblade's right-clicks.
* Meat Hook is a lot harder to land on the real Terrorblade if he has illusions around him.
* Because Dismember targets only one hero, Terrorblade's illusions can potentially save the real Terrorblade if he's caught in it.

* The Reflection of Shadow Fiend cause Presence of the Dark Lord to affect Shadow Fiend, reducing his armor and making it easier for Terrorblade to kill him. Shadow Fiend also doesn't have lots of survivability or control skills in order to escape.
* If Shadow Fiend chooses to go for a right-click build, he'll have a hard time against Terrorblade's high armor.

* She can easily cancel Wukong's Command with Nether Swap.
* Wave of Terror can also detect him while he's on the trees.
Additional:
* Wave of Terror grants flying vision over trees, and its wide effect can hit Monkey King and end Mischief.
* Nether Swap can easily cancel Wukong's Command by swapping him out of the circle.

* With her Nether Swap, Vengeful Spirit can save the life of an ally who gets caught with Flaming Lasso. Nether Swap also makes it highly dangerous for Batrider to attempt a lasso, as it can lead to his own demise far behind enemy lines.
* Wave of Terror's flying vision allows Vengeful Spirit to spot Batrider trying to close in on his target with Firefly.
Additional:
* Nether Swap breaks Flaming Lasso when used on ally and can break if used on Batrider.
* Vengeful Spirit can disable Batrider's Blink Dagger before a fight with Wave of Terror.

* With Nether Swap, Vengeful Spirit can isolate one of the Meepos, making him an easier kill for the team.
* Her Magic Missile gives her an easy way to cancel Meepo's Poof, preventing isolated Meepos from fleeing.

* Reflection illusion will apply Poison Sting to you if hit.
* Conjure Image and Metamorphosis will make quick work of your Plague Wards.
* While ticking down from your poison, Terrorblade can wait until the last possible moment to Sunder a target, either friend or foe.

* Sunder is not affected by Ice Blast and will still swap health with any target as usual.
Additional:
* Sunder allows Terrorblade (or an ally) to regain HP while affected by Ice Blast.
* Terrorblade often buys Manta Style which can dispel Cold Feet

* If Terrorblade's health gets low enough, Terrorblade's Sunder can be used to completely deplete Spectre's health pool without any consequences from Dispersion.
* Terrorblade is one of the few late game heroes that can stand toe to toe and man fight Spectre. Not all is lost if the game goes late when Terrorblade is on your team against Spectre.

* Terrorblade's Sunder is not affected by the Bristleback damage reduction.

* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark,Drow Ranger.

* Heroes with high base damage (Morphling, Tiny, Drow Ranger), heroes with mana burning abilities (Anti-Mage), and Diffusal Blade users (Juggernaut or Riki) will suffer from Reflection's illusions.

* Terrorblade can use Sunder to save his allies who are Doomed.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

Additional:
* Techies' mines can be destroyed by Terrorblade's spammable illusions.
* Terrorblade can push without the fear of dying to mines; he can instead use his illusions to push.

* Terrorblade is one of the strongest carries in the late game, due to his resilience against physical damage, which can be a problem for almost every strong burst physical damage carries, such as Phantom Assassin and Templar Assassin.

* Wave of Terror can reveal a Tinker attempting to hide in the trees and then Nether Swap and Magic Missile will both serve to interrupt/lock him down, should he attempt to town portal or reload.

* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.

* Illusion and heroes with summons are difficult to kill with Chen's single-target offensive spells: Terrorblade, Phantom Lancer, Chaos Knight, Broodmother, Naga Siren, Lycan, Visage. However, Chen can convert enemy summons with Holy Persuasion, as long as they don't bunch up.

* Heroes with illusions and summons can swarm Bane, who has no area abilities: Broodmother, Chaos Knight, Nature's Prophet, Phantom Lancer, Terrorblade

Additional:
* Nightmare can easily cleared by Terrorblade's spammable illusions.
* Almost all of Bane's damage revolves exclusively around single-target effects. Terrorblade can almost always get a Sunder off.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

* Terrorblade starts out with and gains a lot of armor from his agility growth. His illusions also make it difficult for Slardar to focus down the real Terrorblade.

* Heroes that can overwhelm Visage by sheer number like Chaos Knight, Meepo, Terrorblade and Phantom Lancer.

* Heroes with illusions and summons can manfight Night Stalker: Terrorblade, Beastmaster, Broodmother.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

Additional:
* Vengeful Spirit can interrupt Black Hole's channeling through Black King Bar by using Nether Swap from a safe distance.
* Vengeful Spirit's Level 25 Talent can make her Magic Missile pierce spell immunity, giving her another option to use in conjunction with Nether Swap to cancel Enigma's Black Hole channeling through Black King Bar.

* Terrorblade can destroy Tombstone with his Conjure Image and Metamorphosis.

* With her Nether Swap, a well positioned Vengeful Spirit can save the life of a more important ally who gets caught in Chronosphere. Her Vengeance Aura also makes her an unappealing target for Faceless Void.
Additional:
* Nether Swap can save an ally from the Chronosphere.

* Sunder will make Sven a very easy kill if he gets it of on him.
* Terrorblade likes to go late game with his high attack damage, range and agility items.

* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.

* Nether Swap breaks one ally out of Soulbind, and can be used to redistribute the shared damage to Vengeful Spirit herself.

* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer

* Wave of Terror can reduce Legion Commander's survivability during a Duel.
* Magic Missile and Nether Swap disrupts Duels and saves allies.

* Terrorblade with Manta Style and Conjure Image illusions overwhelms Anti Mage.
* Reflection turns Mana Break against Anti-Mage draining his mana making it useful in fights.
* Terrorblade's low mana pool makes him a poor target for Mana Void.
Additional:
* Reflection's illusion carries Mana Break as well, making it useful in fights.

* Heroes that create illusions (such as 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 and the aforementioned Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. (However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse).

* Heroes with high base damage (Morphling, Tiny, Drow Ranger), heroes with mana burning abilities (Anti-Mage), and Diffusal Blade users (Juggernaut or Riki) will suffer from Reflection's illusions.

* Viper's damage over time and lack of disables makes him easy to Sunder.
* Viper's physical damage is mitigated by Terrorblade's high armor.
* Terrorblade under Metamorphosis can quickly kill Viper with heavy physical damage.
Additional:
* Almost all of Viper's damage revolves exclusively around single-target damage-over-time effects. Furthermore, without any hard disables, Terrorblade can almost always get a Sunder off.
* Viper has low mobility and Corrosive Skin doesn't protect against physical damage, which means that Terrorblade under Metamorphosis can quickly kill Viper.
