* Void can be used to cancel Requiem of Souls.
* Crippling Fear prevents Shadow Fiend from using Shadowraze or Requiem of Souls.
* With Dark Ascension and Gem of True Sight, Night Stalker can find and kill Shadow Fiend easily. He is also a tanky hero that can fight Shadow Fiend at any stage of the game.

* 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.

* Night Stalker can easily find Pudge's location during Dark Ascension.
* Void's mini-stun and silence from Crippling Fear at night will stop Dismember, Meat Hook and Rot and preventing Pudge from fighting back.
* Night Stalker has naturally high health, strength gain and common itemization for survivability through magic resistance, making Night Stalker a poor target for Pudge.

* 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.

* Crippling Fear makes Night Stalker one of the best early game gankers to shut down Anti-Mage.
* Night Stalker's low mana pool causes him to take little damage from Mana Void.

* 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.

* 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.

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* With Dark Ascension and Gem of True Sight, Night Stalker can easily find and kill Riki. Riki will also find it harder to kill the tanky Night Stalker than he would many other heroes.

* 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.

* 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.

* With Dark Ascension Night Stalker gains unobstructed vision during night-time allowing him to easily detect mines if he has a Gem of True Sight, but Night Stalker is a melee hero so he has to use Quelling Blade to safely defuse Remote Mines and Stasis Trap.
* Dark Ascension also allows Night Stalker to fly over Proximity Mines without triggering them.
* Crippling Fear is effective in stopping Techies from using Blast Off! and Void is effective in stopping them from running to the safety of their mines.

* 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.

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* 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

* Heroes with mobility/escape mechanisms to dodge Ancient Apparition abilites, or to easily jump on him: Riki, Queen of Pain, Phantom Assassin, Windranger, Bounty Hunter, Spirit Breaker, Night Stalker, Storm Spirit, Juggernaut, etc.

* Dark Ascension reduces vision for the enemy team, which makes it more difficult for Magnus to initiate with Blink Dagger and Reverse Polarity. It is also more likely that Night Stalker will scout out Magnus with Aghanim's Scepter and a Gem of True Sight, after which he can silence Magnus with Crippling Fear.

* 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.

* Night Stalker has a huge, almost instant silence through Crippling Fear. The main problem is that he can get it off while Queen of Pain barely has any vision of him if he creeps up to her during Dark Ascension. She'll have to play very carefully before she gets a Black King Bar or a Eul's Scepter of Divinity.

* 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.

* With Dark Ascension he can keep vision on Slark, disabling his Shadow Dance regeneration. Slark is also too weak to seriously threaten Night Stalker in lane.

* 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.
* Feast cannot compensate for Terrorblade's incoming high damage, due to his low Strength gain.
* 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.

* 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.

* 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.

* 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.

* The long silence of Crippling Fear at night prevents Mirana from escaping with Moonlight Shadow and Leap. She also has really low base health, so Night Stalker can usually kill her during one cast of Crippling Fear at night.
* With Dark Ascension and Gem of True Sight, Night Stalker can find and kill Mirana, and he is a tanky hero capable of fighting Mirana any stage of the game.

* The long silence at night prevents Clinkz from escaping with invisibility if Night Stalker can sneak up on him. He also has really low base health, so Night Stalker can usually kill him alone during one cast of Crippling Fear at night.

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

* 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 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 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.

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

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* Heroes with low health: Lich, Crystal Maiden, Lion.

* Heroes with low mobility that rely on spells: Zeus, Lina, Crystal Maiden.

* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.

* 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.

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

* 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 that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.

* 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.

* 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.

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* 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.

* Night Stalker can easily find Tinker in the trees during Dark Ascension.
* Void's mini-stun will stop Rearm and Boots of Travel.
* Crippling Fear's silence will prevent Tinker from fighting back, as Tinker relies on his spells.
Additional:
* Night Stalker is one of the best heroes to find (and silence) Tinker in the trees during Dark Ascension.

* Night Stalker's Crippling Fear at night prevents Shadow Walk for an extended period of time and his Void will make Phase Boots useless. If Night Stalker has True Sight, he can shutdown Bounty Hunter's sneak kill.

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

* Crippling Fear can silence Faceless Void for a long time, preventing him from using his Time Walk and Chronosphere.

* Crippling Fear prevents Keeper of the Light from using his spells to keep his team alive during team-fights.
* Dark Ascension is very strong against Keeper of the Light, who relies on daytime to be effective.
Additional:
* Keeper of the Light's Aghanim's Scepter upgrade loses much of its power, due to Night Stalker being able to reduce the duration of daytime by a lot.

* Void can interrupt Icarus Dive.
* His Crippling Fear's silence will shutdown a spell caster Phoenix.
* However, Phoenix punishes Night Stalker with Supernova because it will turn night into day, and it has a higher priority than Dark Ascension, effectively canceling the passive bonuses Night Stalker gets from Hunter in the Night.

* Crippling Fear is a good way to shut down and gank Invoker in the early game..
* Void deals good damage to Invoker and makes escaping harder.
* With Hunter in the Night and Void, Invoker can't get away from Night Stalker and won't be able to catch him with Sun Strike during the night.

* The long silence of Crippling Fear at night prevents Weaver from using his Shukuchi or Time Lapse.
* With Dark Ascension and Gem of True Sight, Night Stalker can easily find and probably kill Weaver.
* Hunter In the Night's attack speed bonus removes The Swarm's beetles very quickly.

* Heroes with weaker mobility will struggle to keep up with Night Stalker: Gyrocopter, Ursa, 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.

* Heroes with low mobility that rely on spells: Zeus, Lina, Crystal Maiden.

* Heroes with low mobility that rely on spells: Zeus, Lina, Crystal Maiden.

* Careful not to blink into Riki's Smoke Screen or Night Stalker's Crippling Fear, as these field effects will instantly silence Earthshaker and prevent him from initiating.

Additional:
* Fissure has a short stun and creates an impassable ridge. However, Night Stalker can fly over it during Dark Ascension.
* Night Stalker can find Earthshaker, disable his Blink Dagger with Void, and then take him out with Crippling Fear.
* Earthshaker may fail his blink combo against Night Stalker's team if he is not careful, as he can blink into the silence.

* Crippling Fear is a silence that can last up to 8 seconds during night, rendering Storm Spirit tied limited to his items in a fight.
* Dark Ascension allows Night Stalker to initiate on Storm Spirit across the impassable terrain around the middle lane, rendering Storm vulnerable in the early game and prevent him from snowballing.
Additional:
* Storm Spirit is absolutely helpless if caught within Night Stalker's silence range.
* Common items a Storm Spirit will build will not remove the AoE silence.

* Heroes with low health: Lich, Crystal Maiden, Lion.

* 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 that have long silences, such as Night Stalker and Silencer, will prevent Abaddon from saving his allies effectively and disable the active component of Borrowed Time.

* Void is a potent nuke that is devastating to his low health pool.
* Crippling Fear silence can prevent Puck from casting spells, leaving him vulnerable.
Additional:
* Puck cannot use any of its normal means to survive should Night Stalker catch it within Crippling Fear, and goes down quickly.

* 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.
