* Disruptor can always Glimpse back Io or his target after he Relocated nearby.
* Even better, thanks to the indicator on the ground, you can even preemptively drop Static Storm and Kinetic Field on the spot they will relocate to.
* Thunder Strike and Glimpse are also good tools to bring back an Io that Tethered away in the fog of war.
Additional:
* Glimpse directly negates Relocate.
* Kinetic Field prevents Io from escaping with
Tether.
* Static Storm can silence and damage both, Io and it's tethered target. And it can also mute both, Io and it's tethered target when upgraded with
Aghanim's Scepter.
* Thunder Strike provides vision on him while Slark is invisible.
* Glimpse's range at lvl 3-4 is more than enough to pull him back to a favorable position for your team to group up and kill him.
* Even though he is capable of picking you off and deal enough damage to kill you, Slark will be literally sticking his neck out, since jumping on Disruptor means being on his battleground.
* AoE silence and the ability to mute Black King Bar is deadly to Slark at all stages of the game.
Additional:
* Static Storm and
Kinetic Field locks down Slark, as he cannot use Dark Pact to dispel any disables, or Pounce out while silenced.
* Glimpse puts an end to any attempts at ganking Disruptor or his allies, and also negates Slark's mobility by bringing him back into the fight if he tries to escape with Pounce.
* Soulbind can target both Io and its Tethered ally, allowing Grimstroke and his team to target both with single target spells. Should Io try to
Relocate, Phantom's Embrace can stop its channel to prevent escape.
Additional:
* Grimstroke can catch Io and his Tethered ally easily with
Soulbind as Io has a tendency to
Tether himself with an ally frequently, which also makes them easier targets for
Soulbind.
* Io is highly vulnerable to disables. Hence, Grimstroke's Phantom's Embrace is a great ability to hinder Io's potential.
* Phantom's Embrace cannot be dispelled by Slark's
Dark Pact, and will cause him to suffer damage if he doesn't kill Phantom fast enough.
* Soulbind also cannot be dispelled by Slark's
Dark Pact, and will cause Slark to suffer from a single-targeted ability used on his ally that is also affected by it.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Berseker's Call catches Slark in Shadow Dance, wasting its duration and preventing him from escaping to regenerate.
* Unlike most disables, Dark Pact cannot dispel Berserker's Call and the output damage would be returned by
Blade Mail.
Additional:
* Berserker's Call forces Slark to attack him, even during Shadow Dance.
* Counter Helix will hit Slark in Shadow Dance. It will also trigger frequently against Slark's high attack speed provided by Essence Shift stacks.
* Culling Blade finishes off Slark before he gets a chance to slip away and regenerate his health, preventing him from playing his typical hit-and-run style.
* Ice Blast prevents Io from healing an ally with Tether and prevents healing from
Overcharge
* Io is a common Mekansm builder which is useless if he is affected by Ice Blast.
Additional:
* Ice Blast prevents Io from healing the target.
* Ancient Apparition can easily harass Io on lane with Chilling Touch due to it's high range and damage. This can get even worse if Ancient Apparition buys
Aghanim's Scepter and combines it with items that can give him bonus attack damage and attack speed.
* Chilling Touch combined with
Ice Vortex makes it nearly impossible for Io to escape from
Cold Feet.
Ice Vortex can also make Io and it's tethered target more vulnerable to Ancient Apparition and his allies's magical damage.
* Heroes like Slark,
Witch Doctor and others also tend to suffer in Ice Blast's heal denial.
Additional:
* Ice Blast stops Shadow Dance's passive health regeneration, even when Slark is not in vision.
* Io is a hero who needs to be close to it's tethered target to make it effective, and that's where Leshrac gets the advantage thanks to many of his area-of-effect abilities.
* Lightning Storm will usually hit both Io and its tethered target since both will be close enough for the lightning to jump.
* Diabolic Edict and
Pulse Nova hit all units near Leshrac, meaning he can do colossal damage to both, Io and its tethered target.
Additional:
* Lightning Storm will usually hit both Io and his Tethered target since both will be close enough for the lightning to jump. It can then be followed up by Split Earth.
* Diabolic Edict and Pulse Nova hit all units near Leshrac, meaning he can do colossal damage to Io and his Tethered target.
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina,
Jakiro,
Underlord,
Leshrac,
Dark Seer,
Earthshaker,
Timbersaw,
Crystal Maiden.
* Poison Touch allows Dazzle to harass both, Io and it's tethered target on lane.
Aghanim's Shard upgraded
Poison Touch can also hex both, Io and it's tethered target, preventing them from escaping with Relocate, and also disarming them, silencing them, muting them and rendering them helpless against Dazzle and his allies.
* Io's damage output is one of the weakest, therefore Dazzle will have plenty of time to save an ally with Shallow Grave from gank by Io and it's tethered target.
* Shadow Wave will always hit both, Io and it's tethered target if they are near the ally Dazzle uses
Shadow Wave on, while healing Dazzle's allies near them.
Aghanim's Scepter upgraded
Shadow Wave can bounce on both, Io and it's tethered target, causing them both to take damage and to be attacked by Dazzle. And unlike Io who doesn't get healed while using Tether, Shadow Wave will always heal Dazzle no matter on which of his allies he uses it on.
* Bad Juju will cause both, Io and it's tethered target to lose armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Additional:
* Poison Touch allows Dazzle to harass both, Io and it's
Tethered target on lane.
Aghanim's Shard upgraded
Poison Touch can also hex both, Io and it's
Tethered target, preventing them from escaping with Relocate, and also disarming them, silencing them, muting them and rendering them helpless against Dazzle and his allies.
* Io's damage output is one of the weakest, therefore Dazzle will have plenty of time to save an ally with Shallow Grave from gank by Io and it's
Tethered target.
* Shadow Wave will always hit both, Io and it's
Tethered target if they are near the ally Dazzle uses
Shadow Wave on, while healing Dazzle's allies near them.
Aghanim's Scepter upgraded
Shadow Wave allows Dazzle
Shadow Wave directly on Io and it's
Tethered target which can also bounce on both, Io and it's tethered target, causing them both to take damage and to be attacked by Dazzle. And unlike Io who doesn't get healed while using Tether, Shadow Wave will always heal Dazzle no matter on which of his allies he uses it on.
* Bad Juju will cause both, Io and it's tethered target to lose armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle,
Abaddon.
* Jakiro's area-of-effect ability arsenal allows him to affect multiple heroes at once, giving Io difficulties in saving them as he can only heal one hero at a time with Tether.
* Ice Path can be used to cancel both, Tether and Relocate.
* Jakiro commonly buys Rod of Atos that can be used to cancel Relocate, prevent Io in escaping with Tether and make Io easy target for
Ice Path and
Macropyre.

* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina,
Jakiro,
Underlord,
Leshrac,
Dark Seer,
Earthshaker,
Timbersaw,
Crystal Maiden.
* 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.
* 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 whose abilities can affect multiple enemies at once: Dawnbreaker,
Ember Spirit,
Lina,
Luna,
Jakiro,
Leshrac,
Invoker,
Muerta,
Dazzle.
* Slark's low health and reliance on high built armor from Essence Shift makes him susceptible to Muerta's
Pierce the Veil.
* Muerta cannot be attacked by Slark's physical attacks and Essence Shift during
Pierce the Veil.
* Muerta's Dead Shot and
The Calling can hit Slark even while hidden with
Shadow Dance.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Bulwark blocks much of Slark's basic attack damage, even during Shadow Dance.
* Slark finds it very difficult to have a good early/mid game when pressured in the early game by Spear of Mars and God's Rebuke.
* Spear of Mars and God's Rebuke can hit Slark through Shadow Dance and
Depth Shroud.
* Should Pounce be on cooldown, Slark is very vulnerable inside Arena of Blood.
* 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.
* Slark has no sustained AoE to fight off Phantom Lancer's illusions as they continually spawn.
* Spirit Lance can give vision of Slark by spawning an illusion, making it harder for him to juke and gain the passive bonus from Shadow Dance.
* Phantom Rush helps Phantom Lancer chase down Slark if he tries to escape with
Pounce.
Additional:
* Slark has no sustained AoE damage to deal with a lot of Phantom Lancer's illusions.
* Doppelganger lets Phantom Lancer dodge Dark Pact and Pounce and partially wastes the duration of Shadow Dance.
* Spirit Lance can give vision of Slark via spawning an illusion, making it harder for him to juke and gain the passive bonus from Shadow Dance.
* Phantom Rush helps Phantom Lancer chase down Slark when he jumps away with Pounce.
* Ensnare and
Song of the Siren can be used to cancel both,
Tether and
Relocate and to close the distance on Io.
* Rip Tide combined with illusions from
Mirror Image often finish off Io before he can save himself with
Tether or
Relocate.
* Spirits's weak area-of-effect makes it a bad tool to deal with Naga Siren's illusions from
Mirror Image.
* Once Naga Siren buys Aghanim's Scepter, she can gain access to
Reel In, which not only allows her to cancel both,
Tether and
Relocate, but also to pull Io to herself and her team while he is affected with
Ensnare, similarly to Batrider's
Flaming Lasso.
* Aghanim's Shard upgraded
Song of the Siren can also heal the hero Io and his
Tethered targed try to gank.
Additional:
* Ensnare and
Song of the Siren can be used to cancel both, Tether and Relocate and to close the distance on Io.
* Rip Tide combined with illusions from
Mirror Image often finish off Io before he can save himself.
* Spirit's weak area-of-effect makes it a bad tool to deal with Naga Siren's illusions from Mirror Image.

Reel In, which not only allows her to cancel both, Tether and Relocate, but also to pull Io to herself and her team while he is affected with
Ensnare, similarly to Batrider's
Flaming Lasso.
* Aghanim's Shard upgraded
Song of the Siren can also heal the hero Io and his tethered targed try to gank.
* Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape:
Phantom Assassin,
Magnus,
Slark,
Riki,
Faceless Void,
Storm Spirit.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer,
Death Prophet,
Puck,
Doom.
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom:
Chen,
Dazzle,
Io,
Oracle,
Omniknight,
Witch Doctor,
Winter Wyvern,
Abaddon, etc.
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer,
Death Prophet,
Puck,
Doom.
* Natural Order aura prevents Slark from gaining armor from the agility stolen with Essence Shift.
* Echo Stomp and Earth Splitter can hit Slark through his Shadow Dance ultimate.
* Slark's stats gain is relatively low compared to most agility carries making him quite squishy without his agility-based armor.
* Lich's Chain Frost forces Io to either give up providing buff to his ally with
Tether or suffer devastating damage with his
Tethered ally.
* Lich can easily use Sinister Gaze to disable Io from getting away with
Tether or
Relocate.
* With Dark Ascension he can keep vision on Slark, disabling his Shadow Dance regeneration.
* Night Stalker is very fast so without the Pounce in lane, he can simply out distance him during the night.
* Slark is matched in night vision by only a few heroes, Night Stalker happens to be one of them.
* Outworld Destroyer can disrupt Slark's attacks with Astral Imprisonment either by banishing Slark or his target.
* Slark's low heathpool means he will die quickly to Arcane Orb if he is directly attacked by Outworld Destroyer
* Slark has low intelligence gain, making him easy to finish with Sanity's Eclipse if he tries to run with
Shadow Dance
Additional:
* Arcane Orb deals pure damage, which ignores the armor granted from permanent agility stacks.
* Astral Imprisonment can disrupt any Pounce attempt by banishing the leashed ally.
* Slark's low mana pool makes him more susceptible to Sanity's Eclipse.
* Slark's dependence on Pounce and close range makes him very easy to hit with Purification and
Hammer of Purity.
* Slark's damage, even with a high count of Essence Shift stacks, is easily negated by Omniknight's heals and Guardian Angel.
* Nether Blast will still hit Slark even if he is hidden during Shadow Dance.
* Even though Pugna can rarely target Slark directly with Decrepify, he can still use it defensively on an ally to prevent Slark from getting stacks.
* Despite being somewhat easy to break with Pounce, Pugna can damage Slark and provide vision over him with Life Drain.
* Strafe,
Tar Bomb and
Burning Barrage from
Aghanim's Shard allow Clinkz to quickly kill Io due to its low armor.
* Clinkz iz a hero that very often goes for Orchid Malevolence, and its upgrade
Bloodthorn. Alternatively, Clinkz also loves to buy
Gleipnir. And if Clinkz has both of them, he will be able to root and silence Io and prevent him from escaping with either
Tether or
Relocate.
* Though Slark's large damage output is most certainly a concern for the squishy Crystal Maiden, she does perform fairly well against him when coupled with aid from her team.
* Slark has no innate way to cancel Freezing Field, but the common purchase of Skull Basher does make Slark a substantially greater threat to Crystal Maiden as the game progresses.
* Freezing Field can still hit Slark while he is under the effect of Shadow Dance, and for the early and mid game, the damage output of Crystal Maiden's ultimate outscales Slark's passive regeneration, making a quick use of Freezing Field as soon as Slark uses
Shadow Dance a great way to combat him.
* Crystal Maiden's Frostbite and Crystal Nova are helpful in disabling and slowing the slippery Slark so he can be killed by her teammates.
* Homing Missile can be used to cancel escape attempts with
Relocate.
* Flak Cannon allows Gyrocopter to attack both, Io and his
Tethered target, especially when upgraded with
Aghanim's Scepter.
* Rocket Barrage and
Call Down allow Gyrocopter to deal serious damage to both Io and his
Tethered target.
Additional:

Tethered target, especially when upgraded with
Aghanim's Scepter.
* Rocket Barrage and
Call Down allow Gyrocopter to deal serious damage to both Io and his
Tethered target.
* Living Armor and
Leech Seed can be used to save a hero from a
Relocate gank.
* Overgrowth can be used to cancel escape attempts with
Relocate.
* Once Treant Protector buys Aghanim's Scepter, he will gain access to
Eyes in the Forest, that will allow him to enchant a tree which will grant him unobstructed vision in that location, allowing him to keep his allies alerted on Io and his
Tethered's attempts to gank them, and which can also allow
Overgrowth to damage them and root them if they are within a 800 radius of an tree affected by
Eyes in the Forest.
* Toss and
Avalanche deals heavy damage to Slark in the early game, making Tiny a very dangerous target to gank.
* Tiny has 0 agility, which means Slark's Essence Shift permanent agility steal does not do much against him.
* Terrorblade can easily take advantage of Io's weak durability with Reflection and
Metamorphosis.
* As Io relies on boosting his and his Tethered target's attack speed with
Overcharge, Terrorblade can take advantage of this with
Reflection, which can damage and slow both, Io and his
Tethered target.
* Spirits's weak area-of-effect makes it a bad tool to deal with Terrorblade's illusions from
Conjure Image and
Manta Style.
* Io's damage output is one of the weakest, therefore Terrorblade will have plenty of time to save himself with Sunder.
* However, Terrorblade has no way of stopping Io to escape with Tether or to stop both, Io and his
Tethered target to escape with
Relocate besides
Terror Wave from
Aghanim's Scepter.
Additional:
* Terrorblade can easily take advantage of Io's weak durability with Reflection and

* However, Terrorblade has no way of stopping Io to escape with Tether or to stop both, Io and it's
Tethered target to escape with
Relocate besides
Terror Wave from
Aghanim's Scepter.
* Dark Pact,
Shadow Dance and
Depth Shroud will do nothing against Onslaught and Trample, as they are both ground area-of-effect spells.
* Primal Beast has a gigantic hitbox, which could be difficult for Slark to escape with Pounce should Primal Beast choose to block him. Pounce also does not completely prevent Primal Beast from trampling offensively, as he still has some room to move.
* Primal Beast has a huge health pool making it difficult to shed it with Essence Shift and may allow Primal Beast to build Uproar stacks against him very rapidly.
* If Primal Beast buys an Aghanim's Scepter he can also break
Essence Shift from working on attacks which is a big part of Slark's damage output.
* Shadow Dance does not protect Slark from Shadow Fiend's AoE spells.
* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle,
Abaddon.
* 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,

Shadow Shaman,
Terrorblade,

Ember Spirit,
Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,
Tinker,
Ursa,
Void Spirit.
* Heroes with Break abilities will prevent Slark from regenerating and gaining Essence Shift stacks: Viper,
Shadow Demon, etc.
Additional:
* Viper Strike can disable
Essence Shift and the regeneration aspect of
Shadow Dance.
* Dark Pact doesn't mean a lot against Viper's ubiquitous slows.
* Viper becomes a relevant presence in team fights before Slark can procure his standard items (e.g. Shadow Blade).
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Heroes whose abilities can affect multiple enemies at once: Dawnbreaker,
Ember Spirit,

Ember Spirit,
Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,
Tinker,
Ursa,
Void Spirit.
* 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.
* Slardar's level 25 talent makes
Corrosive Haze undispellable, thus providing his allies vision of Slark.
* Heroes with either magical, physical or pure damage burst: Bane,
Ember Spirit,
Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,
Tinker,
Ursa,
Void Spirit.
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as Lina,
Slark and
Zeus.
* Lucent Beam can be used to cancel both, Tether and Relocate.
* Like with Leshrac's Diabolic Edict,
Lightning Storm and
Pulse Nova abilities. Luna's
Moon Glaives and
Eclipse abilities can make short work of Io and its tethered ally, particularly when upgraded with
Aghanim's Scepter.
Additional:
* Lucent Beam and 0.25s Eclipse Lucent Ministun talent for
Eclipse can be used to cancel both, Tether and Relocate.
* Luna's Moon Glaives and
Eclipse abilities can make short work of Io and its tethered ally, particularly when upgraded with
Aghanim's Scepter.
* With Dust of Appearance, Luna will be able to use
Eclipse on invisible heroes. Be mindful that
Slark is exception because he'll be able to remove the debuff with
Dark Pact.
* Shadow Dance prevents Luna from damaging Slark, and together with
Silver Edge he can easily chase her or escape from her.
* Luna has no way to escape from Pounce's leash, which is especially bad as she is not used to buying
Wind Waker, which is the only way to escape from
Pounce outside of
Black King Bar.
* For the same reasons, Slark makes a very powerful ally for Luna when they are in the same team.
Additional:
* Luna's lack of mobility and escape abilities makes her easily to gank for Slark.
* Shadow Dance helps avoid all the damage from Eclipse.
* For the same reasons, Slark makes a very powerful ally for Luna when they are in the same team.
* Charge of Darkness can be used to escape or counter-initiate against a Relocate gank.
* Greater Bash and
Nether Strike is devastating due to Io's low armor, and can even knock it away from his
Tethered target.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* Illusory Orb and
Phase Shift allows Puck to avoid most ganking attempts.
* Waning Rift and
Dream Coil makes it very hard for Slark to escape bad situations.
* Puck's abilities used together also deals significant magical nuke damage, none of which are targeted and thus cannot be avoided by Shadow Dance.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* Slark will have a hard time killing Sand King because of the survivability he gets from Burrowstrike and Sand Storm.
* Shadow Dance, which usually allows Slark to survive fights, is ineffective against Sand King's AoE damage.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,

* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* Time Dilation while Dark Pact and
Pounce are on cooldown will make these abilities unusable for a long time, reducing his escape potential. However, Time Dilation is dispellable with
Dark Pact so it needs to be timed well.
* Chronosphere will not reveal Slark during Shadow Dance but covers the whole duration of Shadow Dance making him unable to use it to attack or escape. Slark still receives the regeneration benefit from Shadow Dance.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,

Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,

Juggernaut,
Meepo,
Mirana,
Monkey King,
Morphling,
Phantom Assassin,
Phantom Lancer,

Slark,
Sniper,
Terrorblade,
Troll Warlord,

Tusk,
Clinkz,
Sniper,
Slark,
Phantom Assassin,
Void Spirit,
Storm Spirit,
Ember Spirit,
Earth Spirit,
Spirit Breaker,
Lifestealer.
* Heroes that rely on their high mobility such as Queen of Pain,
Slark and
Weaver can be constantly engaged against due to your excellent ability to chase over any terrain. Make sure you carry true sight items (such as
Dust of Appearance or
Gem of True Sight) for invisible heroes that could potentially escape your clutches.
* Pounce's leash prevents Storm Spirit from using Ball Lightning, making it hard for Storm Spirit to escape a gank from Slark.
* Dark Pact can dispel Orchid Malevolence's Soul Burn.
* Tether and Overcharge makes it much harder for Pudge to kill a target with Meat Hook, and Relocate can save the Io's ally while
Dismember is being channeled.
* Dark Pact dispels Dismember if timed correctly.
* Pounce allows Slark to escape Pudge's Rot once Dismember is over, and allows him to dodge hooks.
* Shadow Dance hides Slark and grants him a high degree of mobility, which can make him a difficult target to hook and also protects him from Pudge's Dismember (including allies with an
Aghanim's Shard).
* Drow Ranger's lack of escape abilities makes her an easy target for Relocate ganks.
* A well-timed Dark Pact can dispel Frost Arrows and Gust, letting Slark engage and escape freely.
* Essence Shift is very detrimental for Drow Ranger as the loss of agility means that Marksmanship will also suffer from getting weakened.
* Shadow Dance lets Slark quickly close the gap and deal heavy damage without giving Drow Ranger a chance to retaliate.
* Pounce counteracts Frost Arrows's slow, and also allows Slark easily pin Drow Ranger down or flee from her.
* Depth Shroud from
Aghanim's Shard will allow Slark to save both, himself and his allies and will also allow them to freely fight back against Drow Ranger without her noticing them.
Additional:
* Pounce and items like Shadow Blade makes it very difficult for Drow Ranger to keep her distance from Slark, thereby losing her
Marksmanship bonus.
* Gust is rarely enough to keep Slark at bay, as Drow Ranger has no movement abilities and will simply be chased down afterwards.
* Drow Ranger's heavy dependence on agility also makes her significantly weaker after being drained by Essence Shift.
* Phoenix's limit AoE, damage-over-time abilities give Io plenty of time to save allies with Relocate.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* 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.
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage
Riki,
Queen of Pain,
Puck,
Storm Spirit,
Ember Spirit,
Slark etc.
Additional:
* Blade Fury does not offer any protections against
Essence Shift, as it can go through spell immunity and reduces attribute.
* Slark can pounce away from Juggernaut and he cannot prevent or chase slark.
* Shadow Dance prevent Juggernaut from using
Omnislash altogether, while regen himself at a higher rate. Slark can freely hit juggernaut without any fears of retaliation.
* Pounce helps put Windranger in place, even when she uses Windrun to escape.
* Shadow Dance avoids Windranger's attacks from Focus Fire altogether, and he can regenerate his health and fight back after Windranger uses up all her abilities.
* The stun from Shackleshot and the slow from
Powershot can be both dispelled by Dark Pact, provided Slark casts it at the right moment.
* If Slark sees the Sacred Arrow before it hits him, he can use Dark Pact to remove it a moment later.
* Pounce prevents Mirana from escaping with Leap.
* Slark can survive Mirana's Aghanim's Scepter​ combo with
Shadow Dance.
* Dark Pact rips through Refraction charges and still steals attributes during Refraction.
* Pounce and Dark Pact will still hit Templar Assassin while she is Melded. Since she cannot move, both abilities will be easy for Slark to land.
* Slark's Pounce can be used to dodge Hoodwink's abilities or lock her down.
* Shadow Dance makes Slark unhittable from
Acorn Shot.
* Dark Pact removes all slows from Hoodwink's abilities.
* Hoodwink's already low health output is a great target for Slark's Essence Shift.
* 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.
* Nature's Prophet is extremely easy to gank with Relocate while he's split pushing.
* Tether on a friendly unit can destroy Nature Prophet's trees should he surround himself with Sprout as a defense.
* Pounce also stops Nature's Prophet's
Teleportation.
* Dark Pact easily purges away both slow and disarm effect from Lucky Shot.
* With Pounce now applying leash to the target, Pangolier is helpless against Slark since both his Swashbuckle and Rolling Thunder will be disabled. Pounce also help Slark to easily escape from Rolling Thunder.
* Dark Pact can dispel Venomous Gale and Poison Sting.
* Shadow Dance allows Slark heightened regeneration when out of vision making DoTs effects less threatening.
* Pounce can easily break Static Link, making it less powerful against him.
* Slark is one of the few heroes who can man fight a Razor, because of Essence Shift.
* Shadow Dance can prevent Razor from killing him and may provide an opportunity to kill Razor due to it preventing Razor from attacking Slark.
* Shadow Dance allows Slark to not be targeted by Unstable Concoction, making Alchemist stun himself and making himself vulnerable to the enemy.
* Dark Pact also allows him to just purge off the stun if timed correctly.
* Essence Shift will steal stats over long durations at a time should Alchemist lack the damage to kill Slark.
* Essence Shift deals 20 extra damage by draining one strength per hit, which cannot be reduced or spread by Dispersion.
* Pounce prevents Spectre from escaping with Spectral Dagger.
* Haunt illusions usually don't deal a lot of damage to Slark as he tends to buy a
Shadow Blade, preventing
Desolate's and
Diffusal Blade's damage and activating Shadow Dance's regeneration to make up for any damage caused by
Radiance.
* Slark is a natural carrier of Silver Edge, which helps break both
Desolate and
Dispersion.
* Dark Pact dispels debuffs from Gush, Anchor Smash and even Ravage if timed correctly.
* Kraken Shell cannot restore attributes stolen by Essence Shift or dispel the leash if he gets
Pounced.
* Heroes that can jump on her: Slark,
Queen of Pain,
Anti-Mage
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* Take Aim and
Assassinate allow Sniper to reach Io even if it stays in the backline.
* Heroes with high mobility can approach Sniper: Anti-Mage,
Earth Spirit,
Io,
Nature's Prophet,
Pangolier,
Puck,
Queen of Pain and most notably
Riki.
* Sniper hugely lacks mobility and escape abilities so that he is an easy target for ganks from Slark.
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki,
Tusk,
Clinkz,
Sniper,
Slark,
Phantom Assassin,
Void Spirit,
Storm Spirit,
Ember Spirit,
Earth Spirit,
Spirit Breaker.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* Heroes who have a high mobility (Queen of Pain,
Storm Spirit,
Slark, etc.).
* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void,
Terrorblade,
Ursa,
Weaver,
Broodmother,
Slark,
Abaddon,
Wraith King,
Lifestealer.
* Melee carries who usually buy an early Black King Bar, and have gap closing abilities can be good against the Arc Warden, such as
Slark,
Riki,
Earthshaker with
Aghanim's Scepter,
Sven with
Aghanim's Scepter etc.
Additional:
* Flux is dispelled by Dark Pact.
* Pounce allows Slark to avoid Spark Wraiths.
* Tempest Double allows Slark to build up Essence Shift stacks, especially when it is being used for split pushing.
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying Dagon and
Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage:
Faceless Void,
Terrorblade,
Ursa,
Weaver,
Broodmother,
Slark,
Abaddon,
Wraith King,
Lifestealer.
* Rubick usually positions in the back of a team. Heroes who can sneak up and assault Rubick (e.g. Slark) or damage Rubick from great distance (e.g.
Spectre,
Sniper) should be treated cautiously, as otherwise the matchup usually ends up badly for Rubick.
* Pounce and
Dark Pact together with some attacks can take Rubick down quickly.
* Rubick's spells are ineffective due to the strong dispel effect of Dark Pact.
* Even though Shadow Dance is a great spell to steal, Slark's untargetable nature and his low cooldown spells prevents Rubick from stealing. Also Slark can freely use other abilities for the duration of
Shadow Dance.
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw,
Slark,
Shadow Fiend,
Clinkz,
Bristleback
Nyx Assassin,
Magnus
* Pounce prevents Anti-Mage from using Blink, and lets him disengage from Anti-Mage if needed.
* Essence Shift allows Slark to permanently steal agility from Anti-Mage.
* Shadow Dance stops Anti-Mage from being able to fight back in a slippery situation.
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina,
Lion,
Zeus
* Lion's lack of escapes gives
Slark easier time to catch him through
Pounce.
* Shadow Dance gives
Slark the advantage of being untargetable, nullifying single target abilities (such as non-upgraded
Hex,
Mana Drain and
Finger of Death).
* Dark Pact applies multiple instances of strong dispel on
Slark, which is strong against any of
Lion's disables.
* Lion's low health pool and low armor make him extremely vulnerable to
Slark's damage output.
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina,
Jakiro,
Underlord,
Leshrac,
Dark Seer,
Earthshaker,
Timbersaw,
Crystal Maiden.
* Io can escape from Pit of Malice with Tether or Relocate.
* Relocate can counter Dark Rift's split pushing.
* Heroes with either magical, physical or pure damage burst: Bane,
Ember Spirit,
Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,
Tinker,
Ursa,
Void Spirit.
* Pounce prevents Tinker from blinking away.
* Slark frequently builds Shadow Blade, which allows him to approach Tinker unnoticed. Since Tinker's farming usually covers a significant amount of area on the map, Sentry Wards may not be cost effective.
* Shadow Dance allows Slark to detect both common and unusual wards. Eliminating common ward causes Tinker trouble farming many lanes if he does not know who may be waiting to jump on him. Slark is also uniquely able to identify some of the less common wards used by Tinker, such as those placed on the cliffs at map edges which Tinker uses to give him vision over the trees he uses to hide in.
* Slark's extremely high move speed from Shadow Dance, potentially stacked with
Shadow Blade, allows him to easily follow Tinker between lanes, especially if Tinker has pushed the lanes out.
* Dark Pact dispels Laser's blind.
* 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.
* Upheaval does not interrupt Slark too much, as he can just Pounce out of the area.
* Fatal Bonds and
Shadow Word can be dispelled by Dark Pact.
* 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.
* Dark Pact, if timed correctly, can dispel Wraithfire Blast's stun and slow.
* Since Wraith King has a lot of health and multiple lives, Slark can keep gaining Essence Shift stacks, increasing armor, damage, and attack speed and can beat down Wraith King twice.
* Slark sometimes carries Diffusal Blade to burn mana as an attempt to shut down Reincarnation.
* Because Wraith King has no AoE abilities, Shadow Dance is particularly useful against Wraith King.
* Heroes with either magical, physical or pure damage burst: Bane,
Ember Spirit,
Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,
Tinker,
Ursa,
Void Spirit.
* Slark can detect early Roshan attempts due to Shadow Dance if he frequently checks the Pit.
* Enrage cannot restore attributes stolen by Essence Shift and will reduce his physical damage output.
* Even if Ursa initiates with Earthshock, Slark can Pounce away or use
Dark Pact after Ursa's initiation to avoid Fury Swipes' damage until Earthshock's slow is gone.
* Squishy heroes (Io,
Crystal Maiden,
Lina...), as Earth Spirit can deal tons of damage with Magnetize.
* Pounce's root prevents Earth Spirit from using Rolling Boulder to escape, making it easier for Slark to shut him down especially in the laning phase.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Medusa is especially vulnerable to Essence Shift, as both strength and intelligence contribute to her effective HP, while agility contributes to her damage.
* Dark Pact when timed right can be used to dispel Stone Gaze right after it petrifies Slark, allowing him to keep attacking Medusa throughout the duration.
Additional:
* Medusa cannot chase Slark in any way and has no disable beyond her ultimate, making her unable to stop him getting away and regenerating before coming back to finish her off.
* Essence Shift particularly removes 1 intelligence point per hit, thus lowering Medusa's mana pool's cap and leaving her much more vulnerable in prolonged fights.
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer,
Death Prophet,
Puck,
Doom.
* Slark's Dark Pact allows him to dispel Silencer's debuffs.
* Against a carry Silencer, Essence Shift will lower damage from both Glaives of Wisdom and his basic attack.
* Slark's Dark Pact and Pounce can deny only one Earthbind and Poof can penetrate Shadow Dance if he doesn't build Black King Bar.
Additional:
* Earthbind and
Poof will still hit Slark in Shadow Dance.
* Dark Pact can only remove one Earthbind.
* Ransack will still affect Slark, even if he has a
Black King Bar.
* Tether helps Io escape from Earthbind even if Meepo has Blink Dagger.
* Io's Spirits can pressure Meepo while laning and will usually hit at least one of his clones.
* Heroes that can easily bypass Io's allies to get to Io: Riki,
Tusk,
Clinkz,
Sniper,
Slark,
Phantom Assassin,
Void Spirit,
Storm Spirit,
Ember Spirit,
Earth Spirit,
Spirit Breaker,
Lifestealer.
* Shadow Dance allows Slark to attack Lifestealer for its duration without any way for Lifestealer to fight back, allowing him to steal his stats with
Essence Shift, which also reduces Lifestealer's strength and, therefore, health pool.
* Slark can easily escape Lifestealer with Pounce, and can avoid Open Wounds with
Dark Pact should Lifestealer be forced to itemize for it.
* Slark commonly buys a Silver Edge, which can break Lifestealer's Feast, severely diminishing his damage output and lifesteal.
* Depth Shroud from
Aghanim's Shard allows Slark to save both, himself and his allies with
Shadow Dance while also allowing them to fight back against Lifestealer.
* Batrider's Flaming Lasso can be used to cancel Io's attempts to escape with
Relocate and drag him away from his
Tethered target. And since Io doesn't like buying
Linken's Sphere, he will be always vulnerable to Batrider's initiations.
* Io's tendency to stick close to it's Tethered target can make Io and it's target vulnerable to Batrider's harrasing.
* Aghanim's Scepter upgraded
Flaming Lasso allows Batrider to catch and drag two heroes at once, not just one. Which can potentially turn Io's
Tether against him.
Additional:
* Batrider's Flaming Lasso can be used to cancel Io's attempts to escape with
Relocate and drag him away from his
Tethered target. And since Io doesn't like buying
Linken's Sphere, he will be always vulnerable to Batrider's initiations.
* Io's tendency to stick close to it's Tethered target can make Io and it's target vulnerable to Batrider's harrasing.
* Aghanim's Scepter upgraded
Flaming Lasso allows Batrider to catch and drag two heroes at once, not just one. Which can potentially turn Io's
Tether against him.
* Dark Pact can dispel Flaming Lasso if is used in anticipation, but a Blink initiation from fog can catch the Slark off guard.
* Slark can also take off any Sticky Napalm stacks with Dark Pact in lane.
Additional:
* Shadow Dance's passive can inform Slark when he's under enemy vision, meaning it'll be very hard to catch Slark off-guard with Flaming Lasso.
* Flaming Lasso is dispelled by Dark Pact. Its casting can be prevented with
Shadow Dance or
Depth Shroud (it requires
Aghanim's Shard).
* 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.
* Heroes with strong dispels can remove Primal Roar's stun: Abaddon,
Slark,
Oracle.
* Heroes that can easily bypass Io's allies to get to Io: Riki,
Tusk,
Clinkz,
Sniper,
Slark,
Phantom Assassin,
Void Spirit,
Storm Spirit,
Ember Spirit,
Earth Spirit,
Spirit Breaker,
Lifestealer.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina,
Jakiro,
Underlord,
Leshrac,
Dark Seer,
Earthshaker,
Timbersaw,
Crystal Maiden.
Additional:
* Timbersaw can use Chakram as a scouting tool to find Slark if he tries to
Pounce into the trees.
* None of Timbersaw's abilities require a target to be cast, allowing him to hit Slark inside Shadow Dance.
* Reactive Armor can be effective protection against a Slark who attacks quickly, since the strong armor and health regen cannot be stolen by
Essence Shift.
* Timber Chain makes Timbersaw very mobile, meaning he is among the very few heroes who can actually give chase to a fleeing Slark.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* 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.
* Lycan cannot escape from a Pounce even if he uses
Shapeshift, and has no disabling abilities to stop Slark.
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina,
Jakiro,
Underlord,
Leshrac,
Dark Seer,
Earthshaker,
Timbersaw,
Crystal Maiden.
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as Disruptor's
Kinetic Field or
Slark's
Pounce.
* Quill Spray is very effective against Io, as it has very low armor and has to stay close to the fight to not break its Tether.
* Essence Shift allows Slark to hit Bristleback freely whether on the front or back, stealing attributes and make Bristleback much less tanky.
* Pounce can be used to disengage and recover lost HP with his ultimate passive, and can return to fight in a short period while Bristleback is already injured and got some of his attributes stolen.
* Dark Pact makes it near impossible to keep the
Viscous Nasal Goo debuff on Slark.
* Although Dark Pact cannot dispel
Quill Spray, meaning that Slark will still receive quill stack damage even if he used
Shadow Dance before.
* Slark builds Silver Edge in almost every game, an item that greatly counters Bristleback.
* Phantom Strike allows Phantom Assassin jump directly to Io.
* Coup de Grace can make a short work of Io's low health and armor.
* Slark's Pounce allows him to close the gap on Phantom Assassin and prevent her from escaping with
Phantom Strike.
* As a hero who typically builds Silver Edge, Slark can use it to disable Phantom Assassin's
Blur and
Coup de Grace, thus taking down her attack evasion and drastically reducing her damage output.
* Because Phantom Assassin is always reliant on critical strikes, Slark will have plenty of time to escape with Pounce,
Shadow Dance and
Silver Edge (provided that he purchased it already).
* Depth Shroud from
Aghanim's Shard will allow Slark to save both, himself and his allies from Phantom Assassin with
Shadow Dance, and to freely fightback against her without removing invisibility upon attacking.
* Essence Shift is much more harmful for Phantom Assassin than for other heroes, as losing the agility means that her physical damage will be also reduced, which can also weaken
Coup de Grace if Slark manages to steal lots of agility from her.
* Overall, any attempt for Phantom Assassin to take down Slark will hurt her more than Slark.
Additional:
* Slark's Pounce allows him to close the gap on Phantom Assassin and prevent her from escaping with
Phantom Strike.
* As a hero who typically builds Silver Edge, Slark can use it to disable Phantom Assassin's
Blur and
Coup de Grace, thus taking down her attack evasion and drastically reducing her damage output.

Coup de Grace if Slark manages to steal lots of agility from her.
* Overall, any attempt for Phantom Assassin to take down Slark will hurt her more than Slark.
* Heroes that can easily bypass Io's allies to get to Io: Riki,
Tusk,
Clinkz,
Sniper,
Slark,
Phantom Assassin,
Void Spirit,
Storm Spirit,
Ember Spirit,
Earth Spirit,
Spirit Breaker,
Lifestealer.
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage,
Earth Spirit,
Faceless Void,
Magnus,
Mirana,
Monkey King,
Morphling,
Pangolier,
Phantom Assassin,
Phoenix,
Puck,
Queen of Pain,
Riki,
Sand King,
Spirit Breaker,
Timbersaw,
Tusk.
* Earthshaker's many stuns can lock down slippery heroes like Slark in his
Shadow Dance and
Weaver in his
Shukuchi.
Additional:
* Earthshaker's many AoE stuns help lock down Slark and will often waste the duration of Shadow Dance.
* As a frequent Force Staff buyer, he can later on escape or save teammates from Pounce.
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz,
Slark,
Storm Spirit
* Melee carries during the laning phase: Sven,
Slark
* Heroes with dispels: Legion Commander,
Oracle,
Slark,
Phantom Lancer
* Heroes with either magical, physical or pure damage burst: Bane,
Ember Spirit,
Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,
Tinker,
Ursa,
Void Spirit.
* Heroes who build Black King Bar as either core or situational item will be able to fight back against Nyx Assassin and freely attack him as Spiked Carapace cannot pierce spell immunity at all:
Axe,
Broodmother,
Dawnbreaker,
Enigma,
Huskar,
Jakiro,
Legion Commander,
Lina,
Luna,
Lycan,
Slardar,
Slark,
Troll Warlord,
Witch Doctor.
* Fireblast is a good tool to interrupt Io during its escapes through Tether.
* Ignite can be one of the few spells with enough total damage to out-trade the sustained healing Io provides for its fellow laner.
* However, picking other supports that focus less on the laning phase is generally a better choice against Io.
* Dark Pact dispels Ignite's slow and Fireblast's stun.
* Shadow Dance allows Slark to regenerate HP, even when he is affected by Ignite and Fireblast.
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina,
Lion,
Zeus
* Zeus can deal a huge amount of damage, but he lacks defensive abilities, such as good mobility or resistance. Due to that, he doesn't like to be touched by any means. Heroes with higher damage output and good mobility will often get easily near Zeus and trade damage (eventually causing Zeus's downfall). Such Heroes include: Lycan,
Slark,
Storm Spirit,
Spectre and others.
* Cold Embrace can render the extra attack speed from
Overcharge meaningless.
* Splinter Blast and
Winter's Curse are very affective against Io, as it has to stay close to his
Tethered target.
* Arctic Burn and Splinter Blast's debuffs are can be dispelled with with Dark Pact. Arctic Burn also cannot be used to escape against
Pounce.
* Even though Cold Embrace can protect it's owner from Slark's direct attacks, Slark can still gain Essence Shift stacks from attacking heroes affected by it.
* However, Essence Shift works against allies, and Slark's low health pool means that if he's the target for Winter's Curse, he will go down very quickly as Winter's Curse cannot be dispelled at all.
* 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.
* Nyx Assassin,
Bounty Hunter and
Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with
Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
* Duel is very effective against Io due to its low health and armor.
* Tethered heroes are much harder for Legion Commander to kill in Duels.
* Relocate can cancel Duels and save allies.
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden,
Pugna,
Skywrath Mage,
Io,
Witch Doctor, etc.
* Slark with
Dark Pact
* Heroes that can remove the Track debuff with their skills:
* Abaddon with
Aphotic Shield and
Borrowed Time
* Huskar with
Life Break
* Juggernaut with
Blade Fury
* Legion Commander with
Press the Attack
* Lifestealer with
Rage and
Infest
* Naga Siren with
Mirror Image
* Omniknight with
Heavenly Grace
* Oracle with
Fortune's End and
False Promise
* Phantom Lancer with
Doppelganger
* Slark with
Dark Pact
* Ursa with
Enrage
* Weaver with
Time Lapse
* Tidehunter with
Kraken Shell when damage received reaches the threshold.
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.

Io
*
Thirst allows Bloodseeker to see where Io relocated to, should either Io or the tethered hero have low health.
Rupture forces Io to stay in place, preventing it from using the Tether bonus movement speed to escape.
