* Cold Embrace protects Reality Rift targets.
* Winter's Curse turns Phantasm illusions against Chaos Knight or a teammate.
* Splinter Blast deals decent area damage to Phantasm illusions.
* Arctic Burn's percentage-based damage quickly wears down Chaos Knight's high max health.
Additional:
* Winter Wyvern can make Chaos Knight's illusions attack the real one, provided the player knows who it is.
* Alternatively, Winter's Curse can make Chaos Knight and all his illusions attack one of his allies.
* Cold Embrace protects ally who is focused by Chaos Knight.
* Splinter Blast deals decent area damage to Chaos Knight's illusions.
* Chaos Knight's high health pool and tendency to not build magic resistance items will make Arctic Burn deal a lot of damage to him and his illusions.
* Winter's Curse and
Splinter Blast can devastate Underlord's team when they're grouped up for Dark Rift.
* Wukong's Command and
Boundless Strike combo can easily cause havoc on Chaos Knight by destroying all of his powerful illusions.
* Chaos Knight without Phantasm cannot deal with Jingu Mastery at all.
* Firestorm will do little percentage damage to a small HP hero like Monkey King.
* All aspects of Jingu Mastery benefits ignore Atrophy Aura's base damage reduction.
* Monkey King can get on top of Underlord easily at any stage of the game.
* Black Hole usually catches Chaos Knight with all his illusions.
* Midnight Pulse deals damage based on current health, quickly killing Phantasm illusions.
* Enigma's Midnight Pulse damage can make Underlord suffer heavy damage due to his high health.
* Enigma can catch Underlord and his team off guard with Midnight Pulse and
Black Hole when they teleport using
Fiend's Gate. And
Atrophy Aura offers no defense against them.
* However, Enigma needs to approach Underlord carefully as Underlord can interrupt channeling of the Black Hole with
Pit of Malice and can also use
Firestorm to scout Enigma's location which can also put Enigma's
Blink Dagger on cooldown if Enigma has no
Black King Bar available to use.
* Techies has great area of effect damage to deal with Phantasm illusions.
* Blast Off silences Chaos Knight, stopping him from using his disables and allowing his teammates to walk away from his heavy damage.
* Reactive Tazer will disarm all of Chaos Knight's illusions even if he has activated his Black King Bar.
* In general, heroes that provide vision will see Fiend's Gate coming: Techies,
Templar Assassin,
Treant Protector
* Most Illusion based heroes (like Chaos Knight and
Terrorblade) can't use their illusion beneficially against Sanity's Eclipse's high AoE burst damage.
* Tanky melee heroes that can easily be kited, which allows Outworld Destroyer to deal heavy damage with Arcane Orb from a distance: Sven,
Underlord,
Bristleback.
Additional:
* Arcane Orb's pure damage can do great damage to Underlord.
* Sanity's Eclipse can tear down Underlord's health by a large amount, since his mana pool is very low compare to OD's high mana pool.
* Abaddon could punish Chaos Knight for using his Phantasm and Reality Rift combo on him with Aphotic Shield. Additionally, it provides extra protection against Chaos Knight's potential to take Abaddon down quickly.
* Furthermore, Abaddon's Borrowed Time makes it utterly impossible to burst Abaddon down, effectively reducing the amount of targets Chaos Knight can threaten by 1 for the entire game.
* Maledict cannot be dispelled by Phantasm, and can be used to tag the real Chaos Knight hiding within his illusions.
* If Witch Doctor has an Aghanim's Scepter,
Death Ward will bounce between Chaos Knight's illusions, destroying them quickly.
* However, Death Ward is easily interrupted by Chaos Bolt until Witch Doctor buys
Glimmer Cape or
Black King Bar.
* With his AoE damage, Jakiro can easily kill Chaos Knight's Phantasm illusions.
* Chaos Knight usually doesn't buy a Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.
Additional:
* With his AoE damage, Jakiro can easily kill Chaos Knight's Phantasm illusions.
* Chaos Knight usually doesn't buy a Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.
* Anti-Mage commonly builds Battle Fury, which can deal with Phantasm illusions easily.
* Counterspell, if timed right, will turn Chaos Bolt against Chaos Knight, and can set up for a kill if he is not careful.
* Even if Counterspell is on cooldown, Blink can almost always dodge a Chaos Bolt because of its slow projectile.
* Mana Break will quickly drain Chaos Knight's low amount mana.
* However, beware Anti-Mage is fairly fragile and cannot withstand heavy incoming physical damage at any points in the game, which Chaos Knight excels at. A good player will bait out Counterspell, and retaliate once it's over.
* Heroes that have high health but little to no magic resistance are easy prey for Necrophos, as no matter how high they build their health up, Reaper's Scythe will kill them outright as long as they fall under a certain threshold, and Heartstopper Aura will deal the same amount of damage regardless, decaying their health the longer they stay within range. As such, Strength heroes like Chaos Knight,
Centaur Warrunner or
Magnus are good targets for his ultimate.
* Reaper's Scythe and
Heartstopper Aura deal percentage-based damage, ignoring Underlord's high health.
* Ghost Shroud protects Necrophos from Underlord's damage from Atrophy Aura, and also amplifies all the healing Necrophos receives.
* Innately fragile heroes will die almost instantly to Reality Rift while Chaos Knight has illusions active: Drow Ranger,
Bane,
Necrophos,
Crystal Maiden.
* Sand King's massive area damage output, particularly Epicenter, allows him to quickly take down Chaos Knight and his illusions.
* Sand King can also apply Caustic Finale to illusions with attacks for extra damage when they die.
* Echo Slam will deal a colossal amount of damage to your Phantasms, as will
Fissure at lower levels.
* The area stuns from Aftershock will always stun Chaos Knight's illusions, since they can't use
Black King Bar.
* However, Earthshaker should not attempt to fight a farmed Chaos Knight, since he will be completely obliterated by Chaos Knight's colossal damage output, even if he managed to land an Echo Slam
Additional:
* Echo Slam's damage potential increases due to Chaos Knight's Phantasm illusions.
* Lich's Chain Frost, especially after obtaining its respective talent that provides unlimited bounces, can take out all of Chaos Knight's illusions quickly.
* An Aghanim's Scepter-upgraded
Sinister Gaze can hypnotize Chaos Knight and his illusions while also draining his already low mana pool.
Additional:
* Chain Frost can eliminate Chaos Knight's Phantasm army, especially after he clumped up using
Reality Rift.
* Frost Shield will heavily reduce his army's effectiveness.
* 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).
* Lunar Blessing gives allies bonus damage and armor required to endure against Atrophy Aura early on.
* Eclipse can be devastating for Underlord's team when they're grouped up for Fiend's Gate, it can also be used to intercept arrivals with Fiend's Gate. And Pit of Malice does not prevent Luna to use it.
* To make things even better, Aghanim's Scepter upgraded
Eclipse can finish off Underlord or any of his teammates escape attempts with Fiend's Gate if timed correctly.
Additional:
* Lunar Blessing gives allies bonus damage required to endure against Atrophy Aura early on.
* Eclipse can be devastating for Underlord's team when they're grouped up for Fiend's Gate, it can also be used to intercept arrivals with Fiend's Gate. And Pit of Malice does not prevent Luna from using it.
* To make things even worse, Aghanim's Scepter upgraded
Eclipse can finish off Underlord or any of his teammates escape attempts with Fiend's Gate if timed correctly.
* Heroes that create illusions: 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) 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, but that will require lots of farming for right-click items.
* Quill Spray quickly destroys Chaos Knight's Phantasms.
* Storm's Dispel Magic combined with Thunder Clap deals high damage against Chaos Knight's illusions even in the late game.
* Chaos Knight's reliance on physical damage is easily hindered by Drunken Brawler.
* Chaos Knight's lack of area effect and mobility makes him easily overwhelmed by Primal Split.
Additional:
* Dispel Magic from {U:Storm} can instantly kill Phantasms early on, and can still deal a lot of damage to them late game, revealing the real Chaos Knight.
* Flak Cannon destroys Chaos Knight's illusions very quickly.
* Shadow Fiend can still dish out heavy damage with Requiem of Souls and
Shadowraze while caught in Pit of Malice.
* Using Reality Rift sets up a Reverse Polarity on Chaos Knight and his illusions.
* Shockwave and
Skewer kill Phantasm's illusions quickly, as can
Empower cast on a melee carry.
Additional:
* All Magnus abilities are very good against Chaos Knight's Phantasm illusions.
* Puck's area of effect nukes in the form of Illusory Orb and
Waning Rift clears Phantasm illusions from the early game to mid game.
* Phase Shift can be used to disjoint Chaos Bolt.
* Ravage damages and disables Chaos Knight and his illusions.
* Anchor Smash deals respectable area damage, especially to Phantasms and lowers Chaos Knight's damage.
* Kraken Shell dispels Chaos Bolt and Reality Rift while providing protection from damage.
* Storm Hammer's faster projectile speed and cast time allows Sven to stun Chaos Knight and his illusions before he can cast Chaos Bolt.
* Warcry's armor bonus counteracts Reality Rift's debuff and reduces Chaos Knight's damage output.
* Great Cleave and
God's Strength devastates Phantasm illusions.
Additional:
* Great Cleave is very effective against Chaos Knight's illusions.
* Storm Hammer's radius can catch all of Chaos Knight's illusions at once, especially after Reality Rift.
* Warcry shields Sven and his teammates against Chaos Knight's burst physical damage.
* Strong laners are usually at a disadvantage because of how well Sven can jungle. Heroes such as Dark Seer.
Underlord and
Legion Commander may find that later Sven takes care of them very quickly after some jungle farming.
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map:
Phantom Assassin,
Terrorblade,
Troll Warlord,
Drow Ranger,
Phantom Lancer,
Chaos Knight,
Sven,
Wraith King,
Bounty Hunter,
Alchemist,
Templar Assassin,
Nyx Assassin,
Bane.
* As a frontline tank, the abilities of Underlord is surprisingly spell-cast heavy, and is often great for Rubick to steal.
* Firestorm is a great ability for farming, pushing and serves as a useful teamfight damage source, and even more so when its damage is amplified by
Arcane Supremacy and
Aghanim's Shard.
* It is worth mention that Firestorm has no visible effect on heroes other than damage, and the enemy team may easily mistaken the ability as casted by
Underlord, resulting in unexpectedly soaking up more damage.
* Pit of Malice is a great area control ability in teamfights, capable of trapping multiple heroes in a hazard area.
* Underlord has no immediate reposition ability, and since he usually stays at the front, he can be an easy target for Rubick's
Pit of Malice.
* Fiend's Gate, if stolen, grants Rubick's team great versatility around the map. Creating a surprise gank or appear as a group at the enemy backline during skirmish, escaping as a team from bad situations, or even taking Roshan or enemy highground unexpectedly, the possibility are endless with careful communication among Rubick's team.
Additional:
* All of Underlord's abilities are useful for Rubick to Spell Steal.
* Strong area damage, particularly from Whirling Death and
Chakram, lets Timbersaw clear out illusions quickly.
* Whirling Death directly reduces Strength from both Chaos Knight and his Phantasm illusions, reducing both the damage output and raw health that the hero relies on.
* Reactive Armor quickly builds stacks against Phantasm illusions, making Timbersaw hard to kill.
Additional:
* Reactive Armor helps Timbersaw to endure the damage from
Chaos Bolt and
Reality Rift combo.
* Timbersaw's large amount of pure damage AoE nukes clears Chaos Knight's illusions quickly, drastically reducing his damage.
* Untouchable will significantly slow down Chaos Knight's physical damage with Phantasm.
* Impetus deals double damage to illusions, making it effective against Phantasm.
Additional:
* Untouchable makes all of Chaos Knight's attacks slow therefore he is unable to deal damage, especially his critical damage of
Chaos Strike, also enables Enchantress to escape easily from his attacks.
* However, Reality Rift can still pose a danger to Enchantress because Chaos Knight can decrease a good amount of armor, making it dangerous because of her little armor stat, as he can burst down Enchantress easily if any of Chaos Knight's allies can apply a break on Enchantress.
* In general, heroes that provide vision will see Fiend's Gate coming: Techies,
Templar Assassin,
Treant Protector
* Illusion-based and multi-unit heroes can take advantage of Chaos Knight's lack of area damage: Naga Siren,
Phantom Lancer,
Broodmother
* Heroes who are reliant on illusions or summons: Chaos Knight,
Broodmother,
Naga Siren.
* Heroes who are reliant on illusions: Chaos Knight,
Phantom Lancer,
Naga Siren.
* Once he buys Aghanim's Shard, Dazzle's
Poison Touch can hex enemies, and hex can instantly kill illusions, making Dazzle strong against heroes who rely on illusions. Bear in mind that
Chaos Knight is the exception because his
Phantasms are strong illusions that are immune to abilities that can instantly kill illusions.
* Heroes with strong area damage to destroy Phantasm illusions: Axe,
Ember Spirit,
Legion Commander,
Phoenix
* Heroes with gap-closing abilities will be easy targets for Berserker's Call: Phantom Assassin,
Faceless Void,
Slark,
Chaos Knight,
Morphling,
Queen of Pain
Additional:
* Berserker's Call allows Axe to lock down Chaos Knight and his illusions even through
Black King Bar.
* Counter Helix combined with
Blade Mail clears illusions out in no time.
* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback,
Underlord,
Spectre and
Dragon Knight can be disabled easily with
Sharpshooter's break, reducing their potential in teamfights.
* As long as Windranger is able to identify the real hero among the illusions, heroes relying on them can be easily tagged with Focus Fire: Chaos Knight,
Terrorblade,
Phantom Lancer,
Naga Siren.
* Heroes reliant on illusions or summons: Broodmother,
Chaos Knight,
Naga Siren.
* Heroes with strong area damage to destroy Phantasm illusions: Axe,
Ember Spirit,
Legion Commander,
Phoenix
Additional:
* Ember Spirit is evasive and can dodge close encounters with melee heroes like Chaos Knight. Ember Spirit can't be caught with the slow from Reality Rift, and Flame Guard and Sleight of Fist can bring
Phantasm's illusions down quickly.
* With Aghanim's Scepter, Tinker's Laser completely stops Chaos Knight's damage, forcing him to buy either a Black King Bar for his own survivability while leaving his illusions still vulnerable, or a Monkey King Bar leaving him still vulnerable to Tinker's nukes, though improving his damage.
* Tinker rarely finds himself in the middle of a fight, which is where Chaos Knight typically thrives, and even in the rare cases of being so, at level 3 Tinker's constant rearm and blink away can kite and dodge Chaos Knight's spells reliably, so Chaos Knight has very little catch against Tinker's mobility. This gives Tinker impunity to create more chaos in a teamfight than Chaos Knight can control, laying down the field with March of the Machines and constantly being hit by rockets and lasers.
* Illusion heroes, such as Naga Siren,
Phantom Lancer,
Chaos Knight,
Terrorblade will become strong against Tinker in the late game. 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.
* Io can escape from Pit of Malice with Tether or Relocate.
* Relocate can counter Dark Rift's split pushing.
* Heroes with both illusions and summons, for Io has nothing to deal with multiple enemies at once outside from Spirits's weak area-of-effect: Beastmaster,
Broodmother,
Chaos Knight,
Lycan,
Naga Siren,
Nature's Prophet,
Phantom Lancer,
Shadow Shaman,
Terrorblade,
Visage,
Warlock,
Wraith King.
* Juxtapose allows Phantom Lancer to overwhelm Chaos Knight due to his single-target abilities.
* Manta Style is a natural item from Phantom Lancer's is very harder from Chaos Knight's kill him a lot from Phantom Lancer's illusion and Manta Style from Phantom Lancer's impacted
Juxtapose .
* Doppelganger can be used to dodge Chaos Bolt.
* Since Phantom Lancer builds Diffusal Blade often, it can quickly drain Chaos Knight's low mana pool, leaving him unable to cast spells.
Additional:
* Chaos Knight's single target abilities are difficult to target against Phantom Lancer's illusions.
* Chaos Knight's lack of mobility makes him an easy target for Phantom Lancer to Phantom Rush and drain his already low mana pool.
* Heroes that require burst damage to kill will be difficult for Phantom Lancer to take down: Timbersaw,
Axe,
Bristleback,
Alchemist and
Underlord
Additional:
* Firestorm is very useful for clearing multiple illusions swiftly.
* Pit of Malice will continuously disrupt many illusions, drastically reducing their damage and potency.
* Athropy Aura reduces damage of both Phantom Lancer and his illusions.
* Purification heals a teammate targeted by Reality Rift and heavily damages Chaos Knight and his illusions in the process.
* Guardian Angel blocks all of Chaos Knight's damage for a long duration.
Additional:
* Phantasms can be easily killed with Purification.
* Heavenly Grace dispels the stun from Chaos Bolt and the armor reduction from
Reality Rift.
* Guardian Angel works well against Chaos Knight's overwhelming reliance on physical burst damage.
* In general, heroes with long cooldowns on their abilities or ultimate will struggle against the relentless pressure provided by Dark Rift or Fiend's Gate (Requires
Aghanim's Scepter):
Terrorblade,
Dragon Knight,
Omniknight.
* Dragon Blood's armor bonus greatly reduces the damage dealt by Phantasm.
* Breathe Fire and
Elder Dragon Form's splash damage quickly destroy illusions and reduces their damage output.
* In general, heroes with long cooldowns on their abilities or ultimate will struggle against the relentless pressure provided by Dark Rift or Fiend's Gate (Requires
Aghanim's Scepter):
Terrorblade,
Dragon Knight,
Omniknight.
* Reality Rift lets Chaos Knight bypass the Spirit Bear and jump onto Lone Druid.
* The Spirit Bear's lack of scaling means it dies quickly to Chaos Knight during the late-game.
* Firestorm's percentage damage can quickly demolish the Spirit Bear's high HP
* Pit of Malice will allow allies to easily kite Lone Druid due to his low mobility
* Unlike with other heroes who can summon illusions of themselves, Terrorblade's illusions from Conjure Image have different colors than other illusions which can be seen even by enemy team, which can also make Terrorblade weak even against heroes he naturally counters:
Bane,
Lifestealer,
Spectre,
Chaos Knight,
Spirit Breaker,
Sniper. Terrorblade's only solution to counter this problem is to get
Manta Style as quickly as possible.
* Firestorm deals significant damage to Terrorblade and his illusions from a safe distance.
* Pit of Malice can keep Terrorblade and his illusions under control.
* Atrophy Aura reduces Terrorblade's damage significantly, even during Metamorphosis.
* Fiend's Gate can either bail out Underlord's team away from a bad engagement against a Terrorblade under Metamorphosis or caught Terrorblade off guard if he is not careful, and besides
Reflection, Terrorblade has no other abilities to intercept Underlord nor his team when they use it to start a teamfight. Likewise,
Fiend's Gate can be used to quickly move Underlord's team to the frontlines, to strike Terrorblade and his allies during Metamorphosis's 150 seconds of cooldown, forcing Terrorblade to buy
Aghanim's Scepter that will give him access to
Terror Wave ability.
Additional:
* Atrophy Aura reduces Terrorblade's damage significantly, even during Metamorphosis.
* Firestorm deals significant damage to Terrorblade and his illusions from a safe distance.
* Pit of Malice can keep Terrorblade and his illusions under control.

* Likewise, Fiend's Gate can be used to quickly move Underlord's team to the frontlines, to strike Terrorblade and his allies during Metamorphosis's 150 seconds of cooldown.
* Chaos Bolt and
Reality Rift makes Tiny's low mobility non existent.
* Chaos Strike means Chaos Knight will most likely survive longer in a duel between the two because Tiny has much lower attack speed.
* Chaos Knight has a 3.2 strength growth, making him one of the most tanky heroes and a very difficult target for Tiny to burst.
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven,
Tiny,
Wraith King,
Dragon Knight,
Meepo,
Doom,
Bounty Hunter,
Dark Seer,
Undying,
Alchemist,
Legion Commander.
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother,
Phantom Lancer,
Chaos Knight,
Lycan,
Naga Siren,
Shadow Shaman,
Visage,
Nature's Prophet,
Terrorblade,
Warlock,
Wraith King.
* Firestorm can deal serious damage to Phantom Assassin during laning.
* Pit of Malice prevents Phantom Assassin from either escaping or engaging with
Phantom Strike.
* Phantom Assassin's damage output is entirely physical, therefore Atrophy Aura is very hazardous for her in most of the stages, particularly since it also affects
Coup De Grace, hindering Phantom Assassin's main source of damage.
* Without proper items and any area-of-effect ability/item, Phantom Assassin cannot stop Underlord and his team to escape with Fiend's Gate, and she has nothing to intercept Underlord and his team when they use
Fiend's Gate to teleport on any area of the map outside of
Fan of Knives from
Aghanim's Shard.
Additional:
* Pit of Malice prevents Phantom Assassin from either escaping or engaging with Phantom Strike.
* Phantom Assassin's damage output is entirely physical, therefore Atrophy Aura is very hazardous for her in most of the stages, particularly since it also affects
Coup De Grace Coup de Grace, hindering Phantom Assassin's main source of damage.
* Without proper items and any area-of-effect ability/item, Phantom Assassin cannot stop Underlord and his team to escape with Fiend's Gate, nor she can intercept them if Underlord chooses to teleport on any area of the map.
* Innately fragile heroes will die almost instantly to Reality Rift while Chaos Knight has illusions active: Drow Ranger,
Bane,
Necrophos,
Crystal Maiden.
Additional:
* Reality Rift will disable Drow Ranger's Marksmanship, along with
Chaos Bolt he can keep her locked for enough time to be killed.
* Atrophy Aura reduces Drow Ranger's damage significantly, as she relies on agility to be effective.
* Dark Pact is minimally effective against Phantasm illusions, and Slark lacks area damage otherwise.
* Pounce can be counteracted by Reality Rift.
* Slark is naturally frail and dies quickly to Chaos Knight's burst damage before he can build Essence Shift stacks.
* Be aware, however, that Shadow Dance can make Slark hard to kill as he can't be targeted during its duration.
Additional:
* Phantasms have enough health to survive Dark Pact, and Slark has no other source of AoE damage to deal with them.
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina,
Jakiro,
Underlord,
Leshrac,
Dark Seer,
Earthshaker,
Timbersaw,
Crystal Maiden.
* Heroes with illusion and clone abilities may confuse Bloodseeker, causing him to waste time in fights: Phantom Lancer,
Chaos Knight,
Arc Warden
* Damage reduction from Atrophy Aura prevents Bloodseeker from killing targets and gaining his Thirst bonuses.
* Pit of Malice's area of effect catches Bloodseeker easily, negating his speed bonus during teamfights.
* Dark Rift allows Underlord to transport Ruptured allies to the fountain, rendering it useless.
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight,
Phantom Lancer,
Terrorblade,
Naga Siren,
Broodmother,
Warlock,
Visage,
Nature's Prophet,
Shadow Shaman,
Lycan.
* Pit of Malice can be cast in the path of Spirit Breaker's Charge of Darkness to cancel it.
* Fiend's Gate provides a way to escape from a gank for Underlord and his teammates. Likewise,
Fiend's Gate can be used to ambush Spirit Breaker who has little to no ways of intercepting Underlod and his teammates when they use it to move around the map.
* Phantasm dispels Track, and the illusions make it difficult to Track the real Chaos Knight.
* Bounty Hunter is fragile and can easily be killed by Chaos Knight and Phantasm's illusions.
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map:
Phantom Assassin,
Terrorblade,
Troll Warlord,
Drow Ranger,
Phantom Lancer,
Chaos Knight,
Sven,
Wraith King,
Bounty Hunter,
Alchemist,
Templar Assassin,
Nyx Assassin,
Bane.
* Phantasm gives Chaos Knight a significant advantage against single-target damage dealers: Lifestealer,
Wraith King,
Night Stalker,
Troll Warlord.
Additional:
* Chaos Knight's tanky illusions easily take advantage of Troll Warlord's lack of AoE damage.
* Chaos Bolt can stun Troll for up to 4 seconds and
Reality Rift prevents Troll Warlord from chasing down foes.
* Phantasm increases Chaos Knight's physical damage output up to 4 times and can easily kill Troll Warlord before he has a chance to use Battle Trance or a
Black King Bar.
* Atrophy Aura decreases Troll Warlord's damage.
* Pit of Malice helps lock down Troll Warlord.
* Battle Trance disallows Troll from running out of both Firestorm and
Pit of Malice.
* 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,
Beastmaster,
Warlock,
Wraith King. And even though Chen can convert enemy summons with Holy Persuasion, their much greater numbers will often overwhelm Chen and his creeps.
* Firestorm will easily clear Chen's creeps.
* Pit of Malice will trap Chen and render him helpless.
* Atrophy Aura gives bonus damage to Underlord for each killed creep and weakens Chen's damage output.
* Fiend's Gate can counter Chen's pushing attempts, and he has nothing to intercept it.
* In general, heroes that provide vision will see Fiend's Gate coming: Techies,
Templar Assassin,
Treant Protector
* 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.
* 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.
* Chaos Knight's multiple illusions from
Phantasm can destroy Undying, as Soul Rip can't offset the damage from the high amount of damage from his illusions.
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven,
Tiny,
Wraith King,
Dragon Knight,
Meepo,
Doom,
Bounty Hunter,
Dark Seer,
Undying,
Alchemist,
Legion Commander.
* Phantasm gives Chaos Knight a significant advantage against single-target damage dealers: Lifestealer,
Wraith King,
Night Stalker,
Troll Warlord.
Additional:
* Wraith King has no form of AoE to clear Chaos Knight's illusions from Phantasm.
* Wraith King is very vulnerable if he reincarnates in the middle of his illusions.
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map:
Phantom Assassin,
Terrorblade,
Troll Warlord,
Drow Ranger,
Phantom Lancer,
Chaos Knight,
Sven,
Wraith King,
Bounty Hunter,
Alchemist,
Templar Assassin,
Nyx Assassin,
Bane.
* Firestorm and
Pit of Malice are very disruptive in team fights, completely matching Mars especially since it can all be cast inside Arena Of Blood and also does percentage-based magical damage, negating Bulwark.
* Dark Rift can save any allies of Underlord trapped in Arena Of Blood.
* Atrophy Aura allows Underlord to lane against Mars quite well since he does not have the best base damage during the early game.
* Underlord is a common carrier of both Pipe of Insight and
Mekansm/
Guardian Greaves, allowing his team to combat Mars in the mid to late game.
* Phantasm's illusions make it difficult to land Meat Hook and
Dismember.
* Chaos Bolt is a comparatively low cooldown tool to interrupt Dismember.
* Chaos Strike's lifesteal offsets Rot's damage.
Additional:
* Unlike any other illusion heroes, Chaos Knight is the worst target for Pudge to hook as it will definitely backfire him.
* Phantasm are significantly tankier than most illusion and deal full damage, which will quickly kill Pudge due to his low armor.
* it becomes worse if pudge is affected with Reality Rift, which reduces his already abysmal base armor even lower.
* Low movement speed and low mobility means Pudge will struggle to escape or outrun Chaos Knight in most cases.
* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut,
Lifestealer.
* While Blade Fury is on cooldown, Juggernaut can be easily killed by a standard
Chaos Bolt &
Reality Rift combo.
* Phantasm illusions can tank
Omnislash.
* 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.
* Faceless Void's lack of strong area-of-effect spells makes it difficult for him to fight against Chaos Knight and his Phantasms.
* From a safe distance and if not caught, Chaos Knight can use Reality Rift to pull Faceless Void out of the
Chronosphere which combined with
Chaos Bolt can expose him to being bursted down by Chaos Knight's team before Void even succeeds to escape with
Time Walk.
* Phantasm dispels Ignite and makes targeting the real Chaos Knight much harder.
* Firestorm makes quick work of Treants and
Atrophy Aura gives him temporary damage for every Treant killed.
* Pit of Malice can stop Teleportation channeling.
* Atrophy Aura greatly reduces Nature's Prophet's damage and he has no other good way to deal damage.
* Fiend's Gate can counter split-pushing, which is something that Nature's Prophet relies on a lot.
Fiend's Gate can also be used to either escape from Nature's Prophet or to prepare an ambush on Nature's Prophet, and outside from Nature's Wrath, Nature's Prophet has no other ways to intercept arrivals with
Fiend's Gate.
* Life Drain does not instantly kill the illusions from Phantasm
* Chaos Bolt and
Reality Rift can easily interrupt the channeling from Life Drain.
* Reality Rift makes it harder for Pugna to keep his distance between Chaos Knight.
* Nether Ward barely deals any significant damage on Chaos Knight as Chaos Knight's abilities do not cost a lot of mana
* The overwhelming damage of Chaos Knight and his illusions will do a quick work on Pugna's poor HP pool, or safely remove the Nether Ward from the battlefield.
* Pit of Malice prevents Riki from casting
Blink Strike. or
Tricks of the Trade.
* Atrophy Aura reduces Riki's damage.
* Firestorm can be used to harrass Riki in lane.
* Dark Rift allows Underlord to transport allies from poison damage-over-time to the fountain.
* Underlord usually buys Pipe of Insight that gives a magic resistance to allies, inhibiting the damage from Venomancer abilities.
* Chaos Knight's high health pool makes him resistant to Zeus' burst damage. Phantasm can dispel
Veil of Discord, a typical item purchased by Zeus.
* Zeus is easily overwhelmed by Chaos Knight's strong illusions, as Arc Lightning is not enough to kill them fast enough to have any impact.
* Zeus' low base armor makes him extremely vulnerable to Chaos Knight's high damage output and armor reduction.
* Huskar's low armor and movement speed make an easy target for Chaos Knight to initiate on with Reality Rift and
Chaos Bolt.
* Beside Inner Fire, Huskar has no reliable area of effect ability to clear Phantasm illusions.
* Huskar likes to fight at low health to benefit from his Berserker's Blood, thus vulnerable to Chaos Knight's high burst physical damage.
Additional:
* Chaos Bolt can stun Huskar when he jump in with
Life break, giving 4 seconds maximum for Chaos Knight to deliver a beatdown.
* Reality Rift further reduces Huskar's low armor, boosting Chaos Knight's damage even more.
* Berserker's Blood offer no protection against
Chaos Strike, which deal physical damage.
* Phantasm can be used to dispel the disarm from
Inner Fire.
* Although Huskar can use this to disarm the illusion instead, buying himself some times.
* Chaos Knight can dispel Flux with Phantasm.
* Chaos Knight can use Reality Rift to pull Arc Warden out of Magnetic Field.
* Once Chaos Knight jumps on Arc Warden with Reality Rift, Arc Warden will struggle to escape due to low mobility and lack of stun.
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time:
Phantom Assassin,
Enchantress,
Huskar,
Underlord.
Additional:
* Infernal Blade does damage based on percentage health, and is useful against high health pool hero like Underlord.
* Doom can prevent Underlord from spamming his abilities and most important is to prevent him from using Fiend's Gate to escape.
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane,
Beastmaster,
Bloodseeker,
Clockwerk,
Doom,
Shadow Shaman.
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven,
Tiny,
Wraith King,
Dragon Knight,
Meepo,
Doom,
Bounty Hunter,
Dark Seer,
Undying,
Alchemist,
Legion Commander.
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane,
Beastmaster,
Bloodseeker,
Clockwerk,
Doom,
Shadow Shaman.
* Underlord's
Atrophy Aura reduces Morphling's high base damage gained through agility shift.
* 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.
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map:
Phantom Assassin,
Terrorblade,
Troll Warlord,
Drow Ranger,
Phantom Lancer,
Chaos Knight,
Sven,
Wraith King,
Bounty Hunter,
Alchemist,
Templar Assassin,
Nyx Assassin,
Bane.
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and
Phantom Lancer, or by Heroes that summon other units like
Lone Druid,
Lycan and
Beastmaster.
* Heroes that reduce the damage that Marci can deal during her ultimate, like Razor,
Rubick,
Bane,
Dragon Knight and
Underlord.
* Heroes who relies on illusions and summons (Beastmaster,
Chaos Knight, etc.).
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight,
Spirit Breaker,
Riki, and more.
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: Disruptor,
Death Prophet,
Enigma,
Faceless Void,
Invoker,
Lich,
Magnus,
Mars,
Medusa,
Outworld Destroyer,
Phoenix,
Puck,
Queen of Pain,
Shadow Fiend,

Brain Sap:
Broodmother,
Chaos Knight,
Naga Siren,
Nature's Prophet,
Phantom Lancer,
Terrorblade,
Visage,
Warlock,
Wraith King.
Additional:
* Phantasm's illusions make it difficult for Bane to target Chaos Knight with Nightmare,
Enfeeble, and
Fiend's Grip.
* Chaos Bolt is a comparatively low cooldown tool to interrupt Fiend's Grip.
* Nightmare can be transferred by Phantasm illusions.
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map:
Phantom Assassin,
Terrorblade,
Troll Warlord,
Drow Ranger,
Phantom Lancer,
Chaos Knight,
Sven,
Wraith King,
Bounty Hunter,
Alchemist,
Templar Assassin,
Nyx Assassin,
Bane.
* Phantasm gives Chaos Knight a significant advantage against single-target damage dealers: Lifestealer,
Wraith King,
Night Stalker,
Troll Warlord.
Additional:
* Chaos Bolt can stun Night Stalker outside of Crippling Fears relatively small radius.
* Reality Rift is a great way to force Night Stalker to fight Chaos Knight, a hero with massive health and damage output. It also forces Night Stalker's Crippling Fear off his primary target.
* Night Stalker doesn't have a lot of ways to deal with multiple targets, which makes him vulnerable to Phantasm illusions unless Night Stalker buys
Aghanim's Scepter.
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map:
Phantom Assassin,
Terrorblade,
Troll Warlord,
Drow Ranger,
Phantom Lancer,
Chaos Knight,
Sven,
Wraith King,
Bounty Hunter,
Alchemist,
Templar Assassin,
Nyx Assassin,
Bane.
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane,
Beastmaster,
Bloodseeker,
Clockwerk,
Doom,
Shadow Shaman.
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven,
Tiny,
Wraith King,
Dragon Knight,
Meepo,
Doom,
Bounty Hunter,
Dark Seer,
Undying,
Alchemist,
Legion Commander.
* Heroes that can overwhelm Visage by sheer number like Chaos Knight,
Meepo,
Terrorblade and
Phantom Lancer.
* Melee heroes who may struggle to get close to Sniper: Wraith King,
Kunkka,
Doom,
Tidehunter,
Underlord,
Troll Warlord, and etc.
Additional:
* Sniper's very long range allows him to stay out of Firestorm and Pit of Malice as well as Atrophy Aura range.
* Sniper is very fragile, along with his low movement speed, make an exceptionally easy target for Chaos Knight to initiate on.
* Sniper has no innate ability to deal with Phantasm or escape a
Reality Rift and
Chaos Bolt combo.
* In most cases, Sniper likes to stay far in the backline to deal damage, thus he is vulnerable if Chaos Knight manages to jump in the back line, which will usually spell a quick end for Sniper.
* Heroes with strong area damage to destroy Phantasm illusions: Axe,
Ember Spirit,
Legion Commander,
Phoenix
* Atrophy Aura's percentage-based damage reduction greatly diminishes Legion Commander's overall damage output, even if she has won many Duels
* Legion Commander cannot get out the way of Firestorm because she is stationary.
Additional:
* Atrophy Aura makes it hard for Legion Commander to win Duels.
* Fiend's Gate can be used to save Underlord and his allies from a
Duel or to intercept Legion Commander, because outside from
Overwhelming Odds, Legion Commander has no other area-of-effect abilities.
* Heroes with Attack speed decreasing skills: Jakiro,
Viper
Lich
* As Viper focuses on single-target damage, he has trouble fighting off Phantasm illusions.
* Reality Rift counteracts Viper's slows and reduces his already low durability against physical damage.
Additional:
* Viper has no response to the standard initiation combo of Reality Rift into
Chaos Bolt.
* Phantasm and
Chaos Strike can eliminate Viper almost instantly with it's damage output.
* Besides Nethertoxin, Viper has no other ways of dealing with Phantasm.
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight,
Naga Siren,
Terrorblade.
* Pit of Malice is very good at preventing Primal Beast from entering the fight and stopping Trample damage at all stages of the game.
* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut,
Lifestealer.
* Level 20 talent allows Reality Rift to bypass spell immunity provided by Rage, thus negating the advantage Lifestealer has in his kit.
* The fact that Lifestealer lacks wave clearing and reliable lockdown makes it difficult to fight Chaos Knight's illusions.
* Feast is largely negated by Chaos Knight's high burst damage from Chaos Strike.
Additional:
* Chaos Strike is a strong burst damage passive that allows Chaos Knight to stand up and even survive Lifestealer's attacks. Level 20 Talent: Reality Rift Pierces Spell Immunity allows him to burst down Lifestealer even while he is in Rage.
* Lifestealer's single-target nature will struggle against Chaos Knight's Phantasm illusions and will be forced to itemize for them.
* Heroes who are illusion based, or even heroes who frequently build Manta Style can be cleared quickly by Pangolier's high damage, or lose their damage ouput because of Lucky Shot: Chaos Knight,
Naga Siren
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector,
Meepo,
Crystal Maiden,
Dark Willow,
Underlord,
Naga Siren
* Static Link greatly reduces Underlord damage, while benefits Razor himself, even when in Atrophy Aura's range.
* Underlord is a slow and low mobility hero, and cannot outrun Razor's high movement speed, easily for Razor to absorb his damage with Static Link to the maximum and burst him down from the bonus damages, combine with the armor reduction from
Eye of the Storm .
* Razor has no way to deal with Chaos Knight's multiple illusions from Phantasm.
* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner,
Jakiro,
Leshrac,
Naga Siren,
Underlord.
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane,
Beastmaster,
Bloodseeker,
Clockwerk,
Doom,
Shadow Shaman.
* Heroes the make heavy use of illusions, like Chaos Knight,
Phantom Lancer,
Terrorblade, or
Spectre can suffer from Crystal Maiden, as Freezing Field can quickly kill off the entire horde if not stopped.
* Innately fragile heroes will die almost instantly to Reality Rift while Chaos Knight has illusions active: Drow Ranger,
Bane,
Necrophos,
Crystal Maiden.
* Glimpse will return Underlord or any of his teammates attempting to escape with Dark Rift if timed correctly.
* Underlord is a slow and low mobility hero, easy to set up Static Storm and
Kinetic Field, preventing him from using his abilities as well as preventing him using Fiend's Gate to escape.
* Phantasm removes Glimpse and dispels
Thunder Strike. Additionally, the Phantasm illusions make it difficult to use Glimpse and Thunder Strike on the real Chaos Knight.
* Disruptor's lack of mobility, combined with his lack of innate defense, sets him up for a Reality Rift and a beatdown by Chaos Knight and his illusions.
* Fury Swipes damage is not reduced by Atrophy Aura, essentially bypassing Underlord's only natural defense.
* Enrage can quickly dispel the root of Pit of Malice.
* Ursa cannot effectively fight against Phantasm's illusions with his single-target damage.
* Chaos Bolt's potentially long stun with Chaos Bolt gives Ursa little opportunity to Enrage.
Additional:
* Ursa has no way to clear illusions quickly, making him vulnerable to Chaos bolt and
Phantasm combo.
* Reality Rift can quickly relocate or reinitiate on Ursa once the duration of
Enrage is over.
* Phantasm can be used to dispel Earthshock's slow.
Manta Style is another item that counter Ursa greatly.
* Ursa has low mobility, once jumped on by Reality Rift, Ursa struggles to escape.
* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer,
Chaos Knight,
Naga Siren,
Terrorblade.
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven,
Tiny,
Wraith King,
Dragon Knight,
Meepo,
Doom,
Bounty Hunter,
Dark Seer,
Undying,
Alchemist,
Legion Commander.
* Illusion-based and multi-unit heroes can take advantage of Chaos Knight's lack of area damage: Naga Siren,
Phantom Lancer,
Broodmother
* Heroes with AoE nukes will clear her illusions in no time, especially if they are percentage-damage-based, like Underlord's
Firestorm,
Elder Titan's
Earth Splitter,
Enigma's
Midnight Pulse,
Zeus's
Arc Lightning,
Jakiro's
Liquid Frost from
Aghanim's Shard etc.
To start select enemy heroes in the field above. It's intended to be used with multiple heroes. The more enemy heroes you provide the better results you will get.
This website was made to help you in pick stage of online game Dota 2. It calculates rating for each possible counterpicks based on tips from web-based database made up entirely of user contributions Dota 2 wiki.
You will get the list of recommended hero counters with a list of tips written by Dota 2 wiki contributors explaining why it's good against the particular hero. In comparison to other similar websites, which show only rating based on average hero win rate from dotabuff or similar service.
Take it with a bit of grain of salt, especially if the recommendation has a low rating (<= 1), some heroes
may win a lane in an early game but would lose in late game (and vice versa). That's why sometimes
you could hero names appearing as a counter and as being countered, as on image:
You can also add your own tips, update old data and fix mistakes by editing page on Dota 2 Wiki (it works like Wikipedia - anyone can contribute, you don't even need to register) these edits will appear on this website automatically (data is updated several times per week).
Right now there is no app/overlay that will detect picks automatically (like overwolf dota plus or become the gamer), instead, you can open web version in a steam in-game browser or use mobile version on your smartphone.
