* Feast deals damage and heals Lifestealer based on the target's maximum HP, which is greatly effective against naturally high HP heroes such as Doom.
* Rage allows Lifestealer to become spell immune to negate the magical damage of Infernal Blade and Scorched Earth.
* Doom has no effective means of escape from Open Wounds and
Ghoul Frenzy. This is particularly devastating in the laning stage, where Doom may have to play a much more passive, conservative play style as a result.
* 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.
* Doom does not disable Mana Shield. As such, Doom's damage is largely mitigated by her mana shield. Additionally, Medusa is not reliant on her abilities to be effective during a teamfight, making Medusa an unproductive hero to target.
* Medusa is an ideal Linken's Sphere carrier. Should one be purchased, and without any additional disables, Doom may find that few opportunities exist to effectively lockdown, disable, and kill Medusa.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Whenever Doom casts his ultimate, Centaur Warrunner can cast Stampede and allow the Doomed hero to run away, wasting Doom's ultimate.
Additional:
* Stampede can be used to free an ally from the grasp of Doom. Without any means of effective lockdown, kills can be difficult to secure when against an enemy Centaur Warrunner. Also, Centaur's tendency to have lots of health and HP regen tend to help counter Doom.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Terrorblade can use
Sunder to save his allies who are Doomed.
* 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.

Relocate besides
Terror Wave from
Aghanim's Scepter.
* Due to the nature of the hero, Sniper is typically situated in the back of the fight, potentially making him a difficult target to initiate on and fight.
* Sniper is largely a right-click hero, and as such isn't as an effective of a Doom target as other heroes.
* Thanks to Shrapnel and
Headshot, Sniper is able to effectively 'kite' Doom, preventing him from closing the distance between the two.
* 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.
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane,
Beastmaster,
Bloodseeker,
Clockwerk,
Doom,
Shadow Shaman.
* 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 who can disable Mars but cannot do any damage to him, meaning he just tanks their abilities: Doom,
Magnus.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* Due to Doom's naturally high health, strength gain and common itemization for durability, Heartstopper Aura is particularly effective. The health loss is also large enough that, throughout all stages of the game, the aura effectively neuters the health regeneration granted by Devour.
* Necrophos can help to keep both himself and his allies alive during Doom through his natural regeneration granted by Heartstopper Aura (which is not disabled by Doom), or in the case of an ally, through his
Death Pulse. Additionally, Necrophos is an ideal
Mekansm carrier. Should one be bought, kills against Necrophos' team can be difficult to secure due to the damage-over-time nature of Doom and his abilities.
* Doom typically wants to be a hero that soaks attention from the enemy team and takes the role of an initiator and disabler. As such, Doom is an ideal target for Reaper's Scythe, as it is likely Doom will be at the fore-front of any fight.
* 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.
Additional:

* 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.
* 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:
* 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.
* 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.
* 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.
* Doom generally does not impede Sven in almost any way, provided he has activated God's Strength beforehand.
* The slow applied from Corrosive Skin offsets the movement speed bonus granted by Scorched Earth and the tick-based damage from Infernal Blade and Doom will continually slow Doom down. This allows Viper, much like Sniper, to 'kite' Doom and keep him at a safe distance between the two. Additionally,
Corrosive Skin applies an attack-speed slow which is fairly crippling to a hero such as Doom that, naturally, has a high base attack-time, poor agility gain and builds little attack-speed items.
* Since Doom does not disable auto-cast abilities, Viper's Poison Attack will continue to work. Doom may find it hard to close the distance between himself and Viper, and thusly difficult to effectively lockdown and continually deal damage through his abilities.
* Phantom Lancer's illusions can make it difficult to Doom the real hero. Should Doom figure out the real hero, the illusions can make it difficult to cast any abilities, as their hitboxes can be used to body-block the real Phantom Lancer.
* Phantom Lancer is an ideal Diffusal Blade carrier. With it, he can quite easily deplete Doom's already poor mana pool, potentially making him unable to cast his abilities to escape, retaliate or heal.
* Doom lacks any effective ability to clear waves of creeps and illusions, as the vast majority of his abilities are single-target. Without an answer, Doom may find it difficult to deal with Phantom Lancer's presence.
* 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.
* Doom's
Doom marks Phantom Lancer with a highly visible effect, and also silences and mutes him.
* Heroes with undispellable debuffs will help identify the real Phantom Lancer through visual effects or debuff indicators, provided that it was cast on the real Phantom Lancer to begin with:
* Doom's
Doom marks Phantom Lancer with a highly visible effect, and also silences and mutes him.
* Bloodseeker's
Rupture shows a clear red trail effect on the real Phantom Lancer.
* Ancient Apparition's
Ice Blast will only debuff Phantom Lancer and not his illusions.
* Grimstroke's
Soulbind is undispellable.
* Shadow Demon's
Demonic Purge is undispellable.
* Monkey King's
Jingu Mastery is undispellable and puts a big yellow Mark over his head.
* 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:

Tether against him.
* 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.

Song of the Siren can also heal the hero Io and his tethered targed try to gank.
* 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 who often build Linken's Sphere:
Weaver,
Morphling,
Medusa.
* Heroes with a slow attack rate will find themselves struggling to take out Tombstone, like Doom.
* 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,

Shadow Shaman,
Terrorblade,
Visage,

Wraith King.

Wraith King.
* Heroes whose abilities can affect multiple enemies at once: Dawnbreaker,
Ember Spirit,
Lina,
Luna,
Jakiro,
Leshrac,
Invoker,
Muerta,
Dazzle.
* Heroes with low mana pools (eg.Doom and
Tidehunter) will feel the effects of Silencer's Intelligence Steal far more than others.
* Squishy heroes (Io,
Crystal Maiden,
Lina...), as Earth Spirit can deal tons of damage with Magnetize.
* 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.
* Heroes who often build Linken's Sphere:
Weaver,
Morphling,
Medusa.
* 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 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.

Ember Spirit,
Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,
Tinker,
Ursa,
Void Spirit.
* 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.
* 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.
* Lone Druid is essentially two heroes. Dooming one over the other still leaves Lone Druid or his bear able to do their job during a fight. Additionally, Lone Druid is not hindered as much as other heroes by the silence and mute of Doom since the hero relies more on attacks than abilities.
Additional:
* Doom will be very hestitant to use Doom on the Spirit Bear, and using it on Lone Druid himself will not stop the bear from attacking him especially if True Form has already been used.
* Devour does not work on the Spirit Bear and pushes the lane so Lone Druid can safely farm under tower.
* Besides Lone Druid and
Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
* 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.
* Heroes that can keep Luna locked down for a long time can be a threat (she is very item and spell dependent): Faceless Void,
Legion Commander,
Doom.
* Phantom Strike allows Phantom Assassin jump directly to Io.
* Coup de Grace can make a short work of Io's low health and armor.
* 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.
* High health heroes (Axe,
Doom) fall fast with Fury Swipes stacks.
* 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.
* Doom makes Ursa less disruptive, and it cannot be dispelled with Enrage upgraded with
Aghanim's Scepter.
* Infernal Blade deals high damage to Pudge due to his scaling health and strength gain from
Flesh Heap.
* Using Doom with timing against Pudge who had just activated
Rot would usually kill him.
Additional:
* Doom disables the toggling of Rot and, if cast at the right time, may leave Pudge with a potentially lethal health drain.
* Doom's naturally high health, strength gain and damage output makes him a poor target for Pudge.
* The damage of Doom's Infernal Blade scales with the target's maximum health, which is particularly effective against Pudge due to his naturally high health and further health granted by stacks of Flesh Heap.
* 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.
* Besides Lone Druid and
Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
* 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 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.
* Doom can eats Nature's Prophet's treants with Devour and gains lots of gold.
* Doom can buy Radiance or use his
Scorched Earth to quickly wipe out a swarm of Treants.
* Doom and a ministun from
Infernal Blade's prevents Nature's Prophet from escaping with Sprout and Teleportation.
* 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.
* Doom can easily kill Chen's creeps and obtain their abilities with Devour.
* Scorched Earth's area-of-effect can clear multiple of Chen's creeps at once.
* Doom renders Chen completely helpless, and unable to save himself or his allies with
Hand of God.
Aghanim's Scepter upgraded
Doom also allows Doom to cast
Doom on himself and disable both, Chen and his creeps around him.
* Infernal Blade deals scaling damage and is useful against high HP targets such as Timbersaw.
* Timbersaw is extremely reliant on his abilities to be effective during a team fight - both for mobility, damage and crowd control. Timbersaw offers very little, impactful right-click damage, and thus Doom is particularly crippling against him.
* Additionally, when Doom chooses the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent, Doom disables
Reactive Armor, which effectively removes the durability which Timbersaw is commonly known for.
Additional:
* Doom shuts down Timbersaw completely, negating his mobility and preventing him from doing any damage. It also breaks Reactive Armor's passive bonuses from
Aghanim's Scepter.
* Infernal Blade can stun Timbersaw several times in a fight, potentially interrupting Timber Chain. Also it's useful since Timbersaw has high HP due to the damage scales based on max HP.
* Doom completely takes Windranger out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
Additional:
* Doom completely takes Windranger out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
* Doom has several disable abilities to choose from jungle creeps (e.g. War Stomp,
Ensnare) to deal with Shadow Fiend who lacks escape abilities.
* When Doom combines creep abilities with Scorched Earth,
Infernal Blade, and
Doom, Shadow Fiend most likely will die as he cannot use Shadowraze and Requiem of Souls to protect himself, and also cannot even flee by using
Shadow Blade or
Blink Dagger.
* Although Shadow Fiend has a high physical damage output, Doom has a large health pool to survive it, meaning Doom's combo with high magical damage output will shutdown Shadow Fiend first.
* Doom usually buys Radiance to improve his damage, making his nuke combo more deadly to Shadow Fiend. The blind also prevents Shadow Fiend from landing his attacks often.
* 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.
* 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.
* Io can escape from Pit of Malice with Tether or Relocate.
* Relocate can counter Dark Rift's split pushing.
* Faceless Void relies on Time Walk for mobility and survivability but he can be prevented from utilizing it through
Doom.
* Doom has a high cooldown duration for every ability except Infernal Blade, so he is not significantly affected by Time Dilation.
* Doom alone can easily pick off Crystal Maiden since she is fairly fragile, even with using only basic attacks, Infernal Blade, and
Scorched Earth.
* Doom prevents her from using any abilities in a fight, making her impact negligible.
* Devour allows Doom to acquire a stun, allowing him to cancel Freezing Field without having to use
Doom.
* Arc Warden relies on items and abilities, as well as his Tempest Double, to deal damage to enemies.
Doom effectively denies that and makes Arc Warden useless in fights.
* Infernal Blade's damage is calculated by percentage of maximum health. Since Spectre is usually tanky, it will hurt her more than most normal attacks.
* Doom can take out Spectre out of a teamfight completely. When combined with the level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, it will disable both
Desolate and
Dispersion, taking away her extra damage and durability.
Additional:
* Infernal Blade's damage is calculated by percentage of maximum health, meaning that it will hurt Spectre more than most normal attacks, negating some of her tankiness.
* Doom can pick up several different abilities from neutral creeps using Devour, some of which can be annoying to Spectre.
* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom makes Spectre less disruptive. Combined with
Aghanim's Scepter, it will disable Spectre passive skills, reducing her potential in teamfights.
* Doom is generally tanky and has naturally high health, allowing him to survive Puck's onslaught in any stage of the game.
* His namesake ultimate Doom is one of the best solutions to counter Puck, as it will silence Puck for a lengthy duration. A Puck silenced for more than 3 seconds usually ends up dead.
* In addition, if Doom chooses the Level 25 talent Doom applies Mute, Puck will not be able to use items altogether, most especially
Blink Dagger and
Eul's Scepter of Divinity, making Doom a nightmare to deal with as Puck.
* Doom will make Abaddon unable to use Mist Coil, Aphotic Shield, and the active component of Borrowed Time, also upgraded with
Aghanim's Scepter can break Curse of Avernus and the passive component of Borrowed Time ,which means his allies could be easily disabled or killed.
* Doom pierces spell immunity and can prevent Enigma from casting any spells or using items until the duration of the spell depletes, as well as cancelling a
Black Hole.
* While Doom can be blocked by a
Linken's Sphere, which is a common item on Enigma,
Aghanim's Scepter upgraded
Doom allows Doom to cast Doom on himself to affect enemies near him, and if Doom can combine this with
Blink Dagger, he will be able to jump on Enigma while he is channeling
Black Hole.
Aghanim's Scepter upgraded
Doom can also cancel
Black Hole if any of Enigma's allies affected by
Doom gets too close to him for it's duration, ignoring both,
Black King Bar and
Linken's Sphere.
* Doom completely takes Mirana out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
* Infernal Blade deals scaling damage and is useful against high HP targets such as Tidehunter.
* Doom prevents Tidehunter from casting his
Gush,
Anchor Smash and
Ravage, making him useless in team fights.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can also disable Kraken Shell, reducing his survivability.
* Phoenix's limit AoE, damage-over-time abilities give Io plenty of time to save allies with Relocate.
* Doom shuts down Anti-Mage's escape capabilities with Blink. The ability also deals pure damage, which ignores the protection from Counterspell.
* However, a well-timed Counterspell can reflect it back.
* If Doom has Aghanim's Scepter,
Doom can break Mana Break and Counterspell, weakening both his offense and defense.
* Doom's low mana pool causes him to take little damage from Mana Void.

* Doom prevents Anti-Mage from maneuvering around a fight or escaping from an initiation using
Blink. Additionally, Doom deals pure damage, which is not affected by
Counterspell. This can quickly whittle away Anti-Mage's naturally poor health pool.
* However, Doom must be careful when using Doom as a well-timed
Counterspell can block and reflect it back against Doom himself.
* The Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} will also disable Mana Break and
Counterspell's passive component, which makes Anti-Mage significantly less effective in fights and more susceptible to the high magical damage of Doom's abilities and his allies.
* Doom applies a basic dispel upon cast, so it can remove
Guardian Angel.
* Casting Doom on Omniknight will also prevent him from healing allies with
Purification, or casting buffs like
Repel and
Guardian Angel, basically turning him into a harmless creep.
Additional:
* Doom turns Omniknight into a walking creep, or completely takes out his buffed cores, also removing Heavenly Grace and Guardian Angel in the process.
* With Devour used on Satyr Banisher, Doom will have access to Satyr Banisher's
Purge, which will allow him to remove Heavenly Grace and Guardian Angel.
* Infernal Blade deals scaling damage and is useful against high HP targets such as Elder Titan. It also can interrupt Echo Stomp if quick enough.
* Doom has very low base armor and naturally high HP, so he isn't significantly affected by Natural Order.
* 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:
* Devour can easily eat creeps controlled by Enchant, limiting her ganking potential.
* Doom reduces the amount of healing received by Enchantress and her allies from Nature's Attendants. In addition, when Doom chooses the
Doom applies Break talent, it can also disable Untouchable.
* Heroes with silences: Puck,
Doom,
Riki.
* 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.
* Silencer's
Global Silence and
Doom's
Doom makes Earthshaker temporarily useless.
* Weak damage but high tick rate or persist in a long time: Slark,
Gyrocopter,
Queen of Pain,
Shadow Shaman (
Shackles),
Jakiro,
Pugna,
Doom
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo,
Witch Doctor,
Lycan,
Enigma,
Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer,
Chaos Knight,
Naga Siren (bonus for her
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark,
Gyrocopter,
Queen of Pain,
Shadow Shaman (
Shackles),
Jakiro,
Pugna,
Doom
* 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.
* 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 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 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.
* Doom prevents Storm Spirit from using all of his abilities and items, rendering Storm Spirit useless in a fight.
* 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.
* Ember Spirit cannot use his Activate Fire Remnant to escape while affected by
Doom.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Doom can stop Death Prophet from casting spells, which makes her useless during team fights if she didn't cast Exorcism before the fight, and also nullifies healing from Exorcism and Spirit Syphon. Furthermore, Doom can use
Scorched Earth to chase after her.
* 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.
* Doom is effective against every hero, and Void Spirit is no exception. Being unable to cast spells or items during fights for 16 seconds nullifies his impact entirely.
* Doom has a very versatile build and can consume creeps which has abilities that can stun or provide additional magic resistance.
* Doom's high strength gain and versatility in items can be effective against Void Spirit's magical damage.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Infernal Blade's damage is calculated by a percentage of maximum health, meaning that it will hurt Axe more than most normal attacks, negating some of his durability.
* Doom can pick up several different abilities from neutral creeps using Devour, some of which can be annoying to Axe.
* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom's naturally low attack speed makes Counter Helix less likely to proc, and his high base health allows him to take a few Helixes with no danger.
* Doom makes Axe less disruptive, preventing him from using his skills or items. At level 25, there is a branch of the talent tree that makes
Doom apply Break, allowing Doom to disable Counter Helix, making Axe effectively useless for a lengthy duration.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Axe.
* Doom has low attack speed because of his high Base-Attack-Time, poor agility gain and limited attack-speed granting items which are commonly built. This means Doom will trigger Counter Helix less often and thus is an unideal target for initiation.
* Doom has naturally high HP so it takes longer for Doom to be brought down to the killing threshold of Culling Blade.
* Axe is highly reliant on his abilities and items to be effective during a fight. Without the usage of Berserker's Call and
Blink Dagger due to
Doom, Axe offers very little in the way of damage, effectively removing him from a fight.
* 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.
* A well-timed Doom prevents Nyx Assassin escaping with Vendetta and fighting back with
Spiked Carapace.
* Doom's high health also allows him to easily shrug off Nyx Assassin's burst damage and fend him off.
* 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.
* Both Infernal Blade and
Doom can be used to disable Bane while he is channeling Fiend's Grip.
* A similar effect can be achieved by using Devour on {U:Centaur Conqueror}, which will give him access to
War Stomp.
* Heroes whose abilities can affect multiple enemies at once: Dawnbreaker,
Ember Spirit,
Lina,
Luna,
Jakiro,
Leshrac,
Invoker,
Muerta,
Dazzle.
* Doom completely takes Invoker out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
Additional:
* Doom is a good way to shut down Invoker, preventing from casting spells and using items for a lengthy time, thus forcing him to invest on
Linken's Sphere.
* 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.
* Tinker is heavily dependent on his abilities and Doom prevents him from using any of them.
* This becomes even worse if Doom chooses the level 25 talent {ValueColor:1|Doom applies Mute|25tal} {Symbol:Talent}, which will prevent Tinker from using items such as Blink Dagger.
Additional:
* Tinker is heavily reliant on casting his spells and Doom can disable all of his abilities and items. An
Aghanim's Scepter only makes it harder for Tinker to survive.
* 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.
* Scorched Earth can be used to engage Visage while removing Gravekeeper's Cloak charges.
* Infernal Blade will deal tremendous amounts of damage over time due to Visage's high health pool.
* Doom completely nullifies Gravekeeper's Cloak and prevents Visage from casting spells.
* 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 silencing abilities can be particularly deadly when Slark is trying to escape: Silencer,
Death Prophet,
Puck,
Doom.
* 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.
* Doom makes Ogre Magi less disruptive.
* Infernal Blade effectively negates Ogre Magi's durability.
* With Aghanim's Scepter, he can disable Multicast.
* 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.
* Infernal Blade deals scaling damage and is useful against high health targets such as Bristleback.
* Doom disables Bristleback's low cooldown abilities, preventing him from triggering Warpath. With his upgraded level 25 talent, it also breaks Bristleback's passive, rendering him more vulnerable.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Bristleback.
* Doom prevents Bristleback from casting his two low cooldown abilities, which then prevents him from utilizing
Warpath.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can disable Bristleback and
Warpath, taking away much of his durability and damage potential in team fights.
* 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.
* Scorched Earth deals damage to Clinkz during Skeleton Walk.
* Doom shuts down Clinkz entirely, as it prevents him from casting any of his spells and contributing a large amount of damage in teamfights.
* Doom's low armor makes him weak against Alchemist's high physical damage output.
* Doom can disable
Chemical Rage's increased healing, rendering Alchemist helpless against Doom.
* Attacks from Infernal Blade can deal serious damage to Alchemist as it deals damage based on the hero's maximum health.
* 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.
* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle,
Oracle,
Warlock.
Additional:
* Doom will not only prevent Warlock from casting his abilities in team fights, but also it reduces the healing from Shadow Word.
* Devour allows Doom to acquire a stun from neutral creeps, allowing him to interrupt Upheaval without having to use
Doom.
* 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.
* Doom can completely shut down Dazzle through Doom, as it prevents him from casting his abilities and, by extension, gaining Bad Juju stacks.
* Drow Ranger can be difficult to get on top of, thanks to her Frost Arrows and
Gust. With these two abilities, Drow Ranger is able to effectively 'kite' Doom and minimize his impact during team fights and laning stage.
* Much of Drow Ranger's effectiveness comes from her passive Marksmanship, which is not disabled by Doom.
* Drow Ranger's lack of escape abilities makes her an easy target for Relocate ganks.
* 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.
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom,
Phantom Assassin,
Troll Warlord.
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet,
Night Stalker,
Drow Ranger,
Doom .
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.
