* Phantom Lancer's Doppelganger has a low cooldown and applies a basic dispel on PL, making it hard to keep Corrosive Haze on him.
* Phantom Lancer usually purchases Manta Style which provides another basic dispel to remove Corrosive Haze with.
* Besides Slithereen Crush, Slardar does not have another way to deal with illusions and has a low mana pool, which allows Phantom Lancer with Diffusal Blade to quickly build up illusions while draining Slardar's mana.
* Phantom Rush outruns Guardian Sprint, forcing Slardar to Blink away or use Slithereen Crush defensively to avoid being killed.
* Ogre Magi has no undispellable AoE damage or disables and has nothing to deal with Phantom Lancer's illusions.
* Doppelganger disjoints and dispels Ignite.
* Abaddon can cast Aphotic Shield on any of his allies to immediately dispel Corrosive Haze and/or the stun and the slow components of Slithereen Crush.
* All of Slardar's debuffs are also removed if Abaddon's Borrowed Time triggers.
* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as Skywrath Mage,
Techies,
Juggernaut,
Shadow Shaman, or
Ogre Magi.
* Slardar does not do well against multiple targets, as his only way to damage multiple targets is Slithereen Crush.
* Meepo's Earthbind will root Slardar, making him unable to chase/escape for the time being. Also,
Poof's low cooldown and high damage can burst Slardar down rather quickly.
* Ogre Magi has single-targeted magical-only damage and disables and is less effective against Meepo's clones.
* Heroes who can stun multiple units at once: Dark Willow,
Spirit Breaker,
Slardar,
Invoker, and
Tidehunter.
* Undying saps strength from heroes with Decay, and Ogre Magi's high strength gain will allow Undying to steal more and more strength, becoming stronger with each use.
* Due to the Strength steal from Decay, Undying is normally very tanky, and has high health, making it harder for Ogre Magi to kill him.
* Fire Spirits greatly reduces Slardar's already low starting attack speed (which Bash of the Deep relies on), making the laning phase very hard for him and discouraging Slardar from aggressively threatening lane kills.
* Supernova, ignoring Phoenix's lack of armor and Slardar's high damage single hits, is extremely hard for Slardar to take down on his own, especially after being hit by Fire Spirits.
* Icarus Dive is one of the longest distance escape spells in the game, and can help a good Phoenix escape from Slardar before he gets a
Blink Dagger. However, the high cooldown means Phoenix is vulnerable to backstabs from any roamers after said spell is used.
* Slardar can interrupt an Icarus Dive from completing the flight with both of his stuns, however, likely leading to death if Supernova is on cooldown.
* A lot of the items a Phoenix builds throughout the game naturally counter Slardar. Shiva's Guard,
Heaven's Halberd and
Eul's Scepter of Divinity all stall Slardar's normal attacks in some way, while
Spirit Vessel's percentage-based damage is good against his innate durability.
* Heavenly Grace reduces Fireblast stun time and dispels Ignite.
* Purification can heal damaged heroes if needed.
* Slardar has high priority on building moblity items such as Blink Dagger rather than tank items. Zeus can easily deal large amount of damage to him if not caught out of position first.
* Phantasm dispels Ignite and makes targeting the real Chaos Knight much harder.
* Viper Strike breaks Multicast.
* Corrosive Skin minimizes the damage from Ignite and Fireblast.
* Doom makes Ogre Magi less disruptive.
* Infernal Blade effectively negates Ogre Magi's durability.
* With Aghanim's Scepter, he can disable Multicast.
* Winter Wyvern's
Winter's Curse works very well against the increased attack speed from Bloodlust.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Tidehunter's
Kraken Shell dispels Corrosive Haze and Bash of the Deep's stun if enough damage is taken.
Anchor Smash and Kraken Shell's damage block also reduces Slardar's damage.
* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; Spirit Breaker,
Legion Commander,
Axe,
Puck, and
Slardar.
* Earth Spirit's useful kit of Slows, Stuns, and Silences can set up kills on Ogre Magi and the silence can stop him from using his abilities.
* Puck silences Ogre Magi with
Waning Rift, and
Phase Shift makes Puck untargetable for the duration.
* Bloodseeker's
Rupture forces Slardar to stay still during fights, preventing Slardar from using Guardian sprint to move in and out of fights. This takes away the ability to initiate and re-initiate with Slithereen Crush's low cooldown. Due to the increased move speed from Guardian Sprint, Slardar can lose health at about 160% the rate of normal heroes while under
Rupture. Bloodseeker's
Thirst also gives him enough move speed so that he's one of the few heroes who can outrun or catch up to a Slardar during Guardian Sprint.
* Arc Warden's
Tempest Double is helpful for killing Ogre Magi who lacks AoE damage and disables.
* Terrorblade starts out with and gains a lot of armor from his agility growth. His illusions also make it difficult for Slardar to focus down the real Terrorblade.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Lifestealer's Rage makes him immune to all of Ogre's magical debuffs and also dispels them.
* Ogre's high health pool makes him an ideal target for Feast.
Additional:
* Ogre Magi has nothing against Rage and his high health pool amplifies
Feast.
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback,
Clinkz,
Luna,
Shadow Fiend,
Slardar,
Terrorblade
* 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.
* Slardar's level 25 talent makes
Corrosive Haze undispellable, thus providing his allies vision of Slark.
* Weaver relies on Shukuchi to escape and kite enemy heroes. Slardar's Corrosive Haze lowers armor and reveals Weaver, who is already a very frail target.
* Weaver usually builds Linken's Sphere, Corrosive Haze can be used to pop the spell block, additionally the level 25 undispellable talent will prevent Weaver from removing Corrosive Haze with
Time Lapse, allowing allied heroes to use their abilities on Weaver.
Additional:
* Corrosive Haze lowers armor and reveals Weaver during Shukuchi, who is already a frail target. In addition, Weaver usually builds
Linken's Sphere, and
Corrosive Haze can be used to "pop" the spell block. His level 25 talent can also make Corrosive Haze undispellable by Time Lapse, which puts Weaver in an even worse situation.
* Guardian Sprint can dodge Weaver's bugs with the movement speed bonus.
* A well-timed Fireblast with Multicast can prevent Weaver from escaping with Shukuchi and even
Time Lapse.
* Ignite's high damage early on applies heavy pressure onto Weaver's very small health pool.
* However, the slow from Ignite is generally useless against Shukuchi, and
Time Lapse dispels it if needed.
* Heroes who can provide True Sight or semi-reveal enemy heroes as Nature's Prophet is prone to buying Shadow Blade:
Bounty Hunter,
Slardar,
Spectre,
Zeus,
Spirit Breaker.
* Nature's Prophet treants can be cleared by Ignite or Multicast Hand of Midas
* Fireblast and Unrefined Fireblast prevents Nature's Prophet from using Teleportation.
* The brutal physical damage of Slithereen Crush and
Bash of the Deep can quickly remove Void Spirit's shield and stun him for a while.
* Corrosive Haze provides vision of Void Spirit while he is running away and
Guardian Sprint allows Slardar to quickly close the gap
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven,
Tiny,
Wraith King,
Ogre Magi.
* Heroes who can provide True Sight are always credible threats: Slardar,
Bounty Hunter, especially
Zeus since his
Lightning Bolt provides True Sight without the need to detect her beforehand to apply the debuff. So even a late-coming Zeus can easily scout a large area to reveal her, and she cannot purge herself from his sight with the dispel talent.
* The damage block instances of Refraction can be burned down with Ignite.
* Fire Shield effectively reduces the burst damage from a Meld-charged ambush from Templar Assassin, provided the spell is cast beforehand.
* While Slardar has Guardian's Sprint activated, Powershot cannot slow him and is easier to avoid.
* Slithereen Crush and Bash of the Deep help Slardar put Windranger in place, even when she uses Windrun to escape.
* Corrosive Haze from Slardar is very effective against Windranger's already low armor. This becomes even worse if she has Aghanim's Scepter-upgraded
Windrun, because it also reveals her position and allowing his allies to use their abilities on Windranger.
* Note that the invisibility provided by Aghanim's Scepter-upgraded
Windrun is not broken upon attacking, casting abilities or using items, so it's vital to cast Corrosive Haze beforehand.
* Multicast Fireblasts over the course of fights are a decent nuisance to stall Sven's massive damage output.
* Bloodlust and Ignite gives Ogre Magi's team the movement speed difference needed to chase and/or disengage against a Sven and his Warcry.
* Ignite provides strong damage over time to pressure Sven early on in the laning phase and keep his health low, delaying his transition into the jungle. Ignite is also an easy way to disrupt Blink Dagger, Sven's most popular way of initiation.
* Ogre Magi's presence in the laning phase both in terms of damage and durability keeps high pressure on Sven in lane.
* Purchasing an Aghanim's Shard allows Ogre Magi to greatly reduce the burst damage of Sven, who tends to build items focused on damage per hit instead of attack speed.
* It is difficult for Mars to trade blows with Ogre Magi in the early game thanks to his high base health, resistance and Ignite.
* Bloodlust can assist Ogre Magi or an ally in repositioning against Mars for its move speed bonus.
* Fireblast can interrupt and mitigate Mars from performing his skill combos, especially in combination with
Multicast.
* Shadow Fiend, a normal Shadow Blade builder often relies on its invisibility to escape fights. Corrosive Haze reveals Shadow Fiend and also weakens his already low armor.
* Slardar can use Guardian Sprint with
Blink Dagger or
Shadow Blade to get close, and
Slithereen Crush will stun Sniper and slow him, making him vulnerable to Slardar's teammates.
* Corrosive Haze lowers Sniper's armor and makes Sniper's
Shadow Blade useless, easily killing him with a few attacks.
* Corrosive Haze will reveal Treant Protector even when he is under the effects of Nature's Guise.
* Corrosive Haze works much like
Track, giving the enemy team vision over Riki. While it doesn't give a movement speed or gold bonus, it instead can melt Riki's armor and Slardar can use
Guardian Sprint to catch up to him.
* Slardar's Aghanim's Shard, causes
Slithereen Crush to apply Corrosive Haze even if Slardar does not have vision over him.
Additional:
* Corrosive Haze makes Riki completely vulnerable to Slardar and his allies, as Riki has no easy way of dispelling it.
* Slardar's physical damage with Slithereen Crush and Bash of the Deep amplified by Corrosive Haze can easily kill Riki.
* Corrosive Haze reveals Pudge's location, making it hard for him to use Meat Hook from the fog of war on Slardar's teammates or Slardar himself.
* Slithereen Crush interrupts Pudge while he is using Dismember.
* Guardian Sprint allows Slardar to avoid Meat Hook.
Additional:
* While Slardar has Guardian Sprint activated, Rot cannot slow him and
Meat Hook is easier to avoid.
* Slithereen Crush allows Slardar to interrupt Dismember at close range (when Slardar is not a target).
* Corrosive Haze reveals Pudge's location, making it very difficult for him to land hooks from the fog.
* Guardian Sprint allows Slardar to outrun Bristleback, even when slowed by Viscous Nasal Goo.
* Corrosive Haze's armor reduction makes Bristleback much less tanky.
* Slardar can reveal Clinkz with Corrosive Haze and make him easy to kill, and his
Bash of the Deep also hits hard against Clinkz's naturally low health pool.
* Slardar's Guardian Sprint can catch up with Clinkz's Skeleton Walk.
* The stun and slow from Slardar's Slithereen Crush can hold Clinkz in place.
Additional:
* Clinkz survivability depends entirely on Skeleton Walk. Corrosive Haze not only makes its invisibility useless, but also makes Clinkz even more vulnerable to physical damage.
* Corrosive Haze followed by
Slithereen Crush takes advantage of Alchemist's main weakness, being physical damage before he has the change to improve his surviability with items.
* Bash of the Deep will deal lots of damage during the laning phase.
* Slardar is one of the few meele heroes who can lane against Ursa in the early game, out harassing him with Bash of the Deep, and running away from a bad engagement with Guardian Sprint
* Corrosize Haze can force Ursa to cast Enrage defensively instead of offensively
* With Corrosize Haze, Slardar's team can quickly dispatch of Roshan, denying one of Ursa's greatest advantages
* Corrosive Haze hinders Nyx Assassin's ganking attempts with
Vendetta, as well as reducing his armor and make him very vulnerable due to his low health pool.
* Guardian Sprint allows Slardar to catch up with Nyx Asssassin and finish him off if he has vision over him.
* Corrosive Haze provides True Sight on its target, exposing Bounty Hunter's position regardless of Shadow Walk.
* Guardian Sprint gives a very high movement speed bonus, allowing him to chase Bounty Hunter even if Slardar is tracked.
Additional:
* Bounty Hunter's Shadow Walk is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.
* Ignite can prevent Earthshaker from escaping and/or initiating with Blink Dagger.
* Fireblast and Unrefined Fireblast may help prevent Earthshaker follow through with his combo after landing an Echo Slam.
* 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.
* Stunt from Fireblast can combinated
Multicast after Ogre Magi level 6 canceled from Shadow Shaman's channeling.
* Corrosive Haze and
Bash of the Deep will make short work of Huskar's low armor, even if Slardar is alone.
* Heroes that commonly attack ethereal units will not have any problems against Muerta's Pierce The Veil: Tinker,
Jakiro,
Lina,
Luna,
Pugna or
Ogre Magi,
Enigma,
Batrider,
Techies,
Broodmother,
Dawnbreaker,
Shadow Shaman,
Bane,
Tinker,
Venomancer,
Arc Warden.
* Crystal Maiden's already low armor and easily interruptible ultimate,
Freezing Field can make Slardar her worst nightmare.
Crystal Maiden also often builds
Glimmer Cape which is revealed by Corrosive Haze.
* Slardar can chase Dragon Knight down with
Guardian Sprint and stun him with both
Slithereen Crush and his passive
Bash of the Deep. He can also use
Corrosive Haze to whittle Dragon Knight's armor.
* Slardar can attack through Plague Wards and gain
Bash of the Deep charges, and
Templar Assassin can spill
Psi Blades through Plague Wards too.
* Heroes that can cancel Charge of Darkness: Ogre Magi,
Earthshaker,
Lion,
Rubick,
Lina,
Luna,
Jakiro,
Dawnbreaker,
Alchemist,
Ogre Magi,
Axe,
Shadow Shaman,
Naga Siren,
Mars,
Bane,
Pudge,
Clockwerk.
* Slardar's
Slithereen Crush allows him to stun Spectre and illusions, and
Corrosive Haze prevents her from juking with
Spectral Dagger.
* Heroes with spells that negate invisibility such as Bounty Hunter,
Zeus and
Slardar prevent her from saving her allies with Moonlight Shadow.
* Bounty Hunter and
Slardar both have ultimates (
Corrosive Haze and
Track) that reveal Invoker through Ghost Walk.
* Heroes with armor reducing abilities greatly hinder Visage's defense like Slardar and
Dazzle.
* Heroes rely on their debuff to control the opponent will have a hard time against Press the Attack: Venomancer,
Earth Spirit,
Ogre Magi
* With armor items like Solar Crest or
Assault Cuirass combined with Bash of the Deep, Slardar can easily tank the
Duel, If not dueled himself, he can drop
Legion Commander's armor during duel and/or buff his teammate and save them, leaving her only the choice of dueling supports which can also be saved with fast Blink into Slithereen Crush.
* Medusa cares less than other heroes about armor reduction, since
Mana Shield blocks 70% of all damage without taking armor/magic resistance into consideration. This makes 60% of your Corrosive Haze ineffective until Medusa's mana is drained.
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter,
Bristleback,
Slardar.
* Ogre Magi only deals magical damage, which Anti-Mage is exceptionally resistant due to Counterspell.
* Anti-Mage dispels Ignite with
Manta Style.
* Ogre Magi has a very large mana pool which means Anti-Mage can do large amounts of damage to him with Mana Break and Mana Void.
Additional:
* Anti-Mage can kite Ogre Magi who has low mobility by Blink and his intelligence gain and build making
Mana Void deal more damage.
* Counterspell well timed makes harass Fireblast and Ignite.
* Slardar deals entirely physical damage. He does not have to worry about Counterspell.
* Slithereen Crush and
Bash of the Deep prevent Anti-Mage from using Blink, the latter even if Anti-Mage activates
Black King Bar.
* Corrosive Haze allows allies to take down Anti-Mage before he has a chance to Blink, and maintains vision over him even if he does Blink away.
Additional:
* Slithereen Crush and Bash of the Deep deals physical damage, bypassing the magic resistance bonus from Counterspell
* Corrosize Haze significantly increases the damage dealt against Anti-Mage, and makes it harder for him to flee with Blink, although Anti-mage can block its casting with with Counterspell
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.
