* 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.
* 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.
* Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.
* 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 Sniper who is somewhat competent at positioning is hardly going to be affected by any of Dark Seer's spells thanks to Take Aim.
* However, an illusion of Sniper made with Wall of Replica is extremely powerful, and hard to deal with.
* 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.
* Fortune's End dispels Ion Shell and Surge, making any gank attempt on Dark Seer in the laning phase likely to succeed.
* Fate's Edict prevents all magical damage that comes from Dark Seer's abilities.
* Fortune's End dispels Ion Shell on creeps, which Dark Seer relies on to farm and zone.
Additional:
* Fortune's End can dispel Ion Shell, a skill that helps Dark Seer immensely in the laning phase, as well as
Surge, a move-speed buff, effectively allowing Oracle to control Dark Seer, especially in the laning phase.
* 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.
* 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.
* 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.
* 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.
* 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.
* The constant dispel from Demonic Purge will make any attempt to save the victim or himself by Surge become futile. For what it's worth, Demonic Purge will also dispel
Ion Shell.
* 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.
* 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.
* 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.
* X Marks the Spot prevents Dark Seer or his allies from escaping with Surge.
* 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.

* 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.
* Dark Seer's strength lies in his high-mana cost skills. So Mana Break can be a great nuisance for him, since it can reduce his mana and prevent him from casting his spells.
* Mana Void can deal a lot of damage if Dark Seer spent a lot of mana on his abilities.
* 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.

* 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.
* Spell Steal will easily steal all abilities from Dark Seer.
Additional:
* Spell Steal can perfect from Rubick's steal all abilities from Dark Seer. Rubick's always purchase
Aghanim's Scepter can two stolens abilities from Dark Seer's and waiting for seconds for second stolen abilities (example: combinated Vacuum and Wall of Replica) and many different combination.
* A good positoning from Rubick's Spell Steal waiting steal abilities from Dark Seer
Wall of Replica and illusion from
Wall of Replica Dark Seer's can fighting with effect from outcome steal
Wall of Replica from Rubick's.
* Combinated Rubick's steal Surge and
Blink Dagger is very important catch from Dark Seer's and enemies.
* Rubick's Telekinesis can lifted up Dark Seer or enemy heroes and throw to
Wall of Replica from Rubick's steal.
* 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:

* 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.
* 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.
* 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 whose abilities can affect multiple enemies at once: Dawnbreaker,
Ember Spirit,
Lina,
Luna,
Jakiro,
Leshrac,
Invoker,

Shadow Shaman,
Terrorblade,

* Dark Seer's only disable is Vacuum. Though he starts off with high armor and health, he'll eventually have a hard time dealing with high mobility heroes such as Weaver or
Queen of Pain.

* In general, heroes who are melee with no way to fight back can be very easily poked by Monkey King to gain his Jingu Mastery stacks: Dark Seer,
Riki,
Rubick.
* Strong laners are usually at a disadvantage because of how well Sven can jungle. Heroes such as Dark Seer.
Underlord and
Legion Commander may find that later Sven takes care of them very quickly after some jungle farming.
* 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.
* The haste provided by Dark Seer's
Surge or a {Rune:Haste} renders Lich's slows ineffective.
* Phantom Strike allows Phantom Assassin jump directly to Io.
* Coup de Grace can make a short work of Io's low health and armor.
* With Normal Punch from
Aghanim's Scepter, Dark Seer can gain an advantage against heroes who rely on evasion as
Normal Punch has true strike:
Phantom Assassin,
Windranger,
Hoodwink.
* 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.

* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer,
Chaos Knight,
Naga Siren,
Terrorblade.
* Dark Seer can take great advantage of Divided We Stand by putting an Ion Shell on a clone in order to harass them effectively.
* Vacuum can take a single Meepo and disable him for Dark Seer and his teammates to take out.
* 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.
* Ion Shell destroys Refraction's protection stacks in short time.
* Surge ignores the massive slow from Psionic Trap.
* 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 that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster,
Broodmother,
Enigma,
Nature's Prophet,
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.
* Dark Seer's Vacuum and
Ion Shell can clear a wave of Chen's Creeps effectively.
* Surge applies haste movement and negates the slow from
Penitence, allowing Dark Seer to easily escape from Chen and his creeps.
* Dark Seer's full combo from Dark Seer's Vacuum,
Wall of Replica and
Normal Punch from
Aghanim's Scepter can often kill Chen or any of his allies before he can save them with
Hand of God.
Additional:

Penitence, allowing Dark Seer to easily escape from Chen and his creeps.
* Dark Seer's full combo from Dark Seer's Vacuum,
Wall of Replica and
Normal Punch from
Aghanim's Scepter can often kill Chen or any of his allies before he can save them with
Hand of God.
* Venomancer is a low health hero and low range hero who is easy to harass with Ion Shell on a creep in the early game.
* Venomancer depends entirely on all his slows to keep distance or chase, but since Surge ignores slows, it is nearly impossible for Venomancer to hunt or run away from Dark Seer or his surged teammates.
* Heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice:
Sven,
Tiny,
Wraith King,
Dragon Knight,
Meepo,
Doom,
Bounty Hunter,
Dark Seer,
Undying,
Alchemist,
Legion Commander.
* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: Luna's

* Io can escape from Pit of Malice with Tether or Relocate.
* Relocate can counter Dark Rift's split pushing.
* Drow Ranger's lack of escape abilities makes her an easy target for Relocate ganks.
* Phoenix's limit AoE, damage-over-time abilities give Io plenty of time to save allies with Relocate.

Keeper of the Light,
Huskar,
Dark Seer
* Dark Seer can increase the movement speed of allies with
Surge, breaking Static Link.
* Heroes with hastes: Dark Seer,
Lycan
* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: Clinkz,
Pugna,
Nature's Prophet,

Dazzle,
Oracle,
Bane,
Pugna,
Tusk,
Winter Wyvern,
Io,
Underlord,
Treant Protector and
Keeper of the Light.
* Dark Seer can pull together Spectre's illusions with
Vacuum, and
Wall of Replica creates an illusion of Spectre that deals massive damage.
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster,
Broodmother,
Enigma,
Nature's Prophet,
Visage,
Warlock,
Wraith King.
* Abilities that deal low damage with high amounts of instances are irrelevant against Pudge during Flesh Heap's active: Gyrocopter's
Rocket Barrage and
Dark Seer's
Ion Shell are just a couple examples.
* 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.
* 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.
* Ion Shell zones out Broodmother in the laning phase, and can kill her spiderlings if used on one Spiderling in a group.
* Vacuum can pull Broodmother out of the treeline.
Additional:
* Ion Shell is a very powerful weapon against Broodmother's Spiderlings and makes her laning much harder.
* 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,

* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer,
Chaos Knight,
Naga Siren,
Terrorblade.
Additional:
* Ion Shell helps taking down illusions quickly, making it easy to identify the real Phantom Lancer.
* Surge allows Dark Seer and his teammates to run away from Phantom Lancer, who relies on his
Phantom Rush to chase enemies.
* 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,

* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster,
Broodmother,
Enigma,
Nature's Prophet,
Visage,
Warlock,
Wraith King.
* 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
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 it's
Tethered target to escape with
Relocate besides
Terror Wave from
Aghanim's Scepter.
* Dark Seer's Vacuum and
Ion Shell allows him to clear a wave of Terrorblade's illusions.
* Because Terrorblade often builds items that require Ultimate Orb like
Manta Style and
Eye of Skadi, Dark Seer can create a very strong illusion of Terrorblade with
Wall of Replica and
Normal Punch from
Aghanim's Scepter.
* If Dark Seer can use Vacuum to help teammates land their AoE abilities, Terrorblade will be quickly killed before he even gets a chance to use Sunder.

* 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 that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer,
Chaos Knight,
Naga Siren,
Terrorblade.
* 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.
* Living Armor can be destroyed quickly with Ion Shell.

Broodmother,
Enigma,
Nature's Prophet,
Visage,
Warlock,
Wraith King.

Ember Spirit,
Leshrac,
Lina,
Luna,
Nyx Assassin,
Phantom Assassin,
Skywrath Mage,
Tinker,

Viper,
Venomancer,
Huskar,
Ember Spirit,
Dark Seer,
Sand King,
Doom,
Dawnbreaker. However, this also means they are easily stunned.
* 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.
* 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 escape abilities: Anti-Mage
Dark Seer

Windranger
Weaver can kite Lifestealer due to him having no lockdown.

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.

Dark Seer
* Heroes with fast movement abilities will suffer huge damage when afflicted by Rupture:
Spirit Breaker,
Earth Spirit,
Dark Seer.
Rupture can deal a lot of damage to either a surged Dark Seer or his allies and prevent the target from getting into position.
Additional:
*
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.
