Slardar/Counters

Bad against...

 * is able to dispel Corrosive Haze and Slithereen Crush stun/slow from any allies Oracle chooses to cast it on.
 * can also be cast on Slardar to prevent him from proccing his Bash of the Deep.


 * Abaddon can cast 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 triggers.


 * Phantom Lancer has a low cooldown basic dispel from, making it hard to keep Corrosive Haze on him. Can also build and.
 * Slardar does not do well against illusions and has a low mana pool, making Phantom Lancer with annoying, to say the least.
 * means you can't Guardian Sprint away from his illusions either, forcing you to Blink, Slithereen Crush or get your cancelled.


 * Slardar does not do well against multiple targets, as his only way to damage multiple targets being Slithereen Crush.
 * Meepo's will root Slardar, making him unable to chase/escape for the time being. Also, 's low cooldown and high damage can burst Slardar down rather quickly.

Others

 * cares less than other heroes about armor reduction, since blocks 60% of all damage without taking armor/magic resistance into consideration. This makes 60% of your Corrosive Haze ineffective until Medusa's mana is drained.
 * 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.
 * dispels Haze and stun if bursting him is attempted often leading to Slardar's team being baited into . Also reduces Slardar's already low damage, so Tidehunter stays tanky even against Slardar.
 * 's 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 . Bloodseeker's  also gives him enough move speed that he's one of the few heroes who can outrun or catch up to a Slardar during Sprint.
 * Slardar relies on initiation, so any illusion-based hero (especially with ) can scout you out and/or cancel your blink.
 * Illusion heroes like Phantom Lancer, Luna, Arc Warden.

Items

 * ,, , can reduce the value of your Corrosive Haze with constant misses and can be hard for Slardar to itemize against, requiring ,  or both. Same goes true for his allies that want to take advantage of the armor reduction.
 * and can be a pain to deal with until Slardar gets a.

Good against...

 * Invisible and fragile. Riki lacks a good option against Corrosive Haze: Riki will not win most straight-up fights even without being stunned, and doesn't have nearly enough health or armor to survive being focused on with Corrosive Haze. Slardar's Guardian Sprint is usually enough to chase effectively, and even Riki's ultimate will rarely deal enough damage to matter much against Slardar. If you find yourself in this untenable position it is recommended to use  aggressively or have a support interfere with Slardar.


 * Clinkz is fragile, and relies on to escape from battles quickly. Corrosive Haze grants True Sight on Clinkz, making his invisibility useless, and makes him even more squishy for the time being. Do not underestimate Clinkz however, as late game, Clinkz can tear down most heroes with  and  along with  which is commonly built by Clinkz.


 * Bounty Hunter's is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.

 * Weaver usually builds, Corrosive Haze can be used to "pop" the spell block of , letting Allied heroes use their abilities on Weaver.


 * Shadow Fiend, a normal builder often relies on its invisibility to escape fights. Corrosive Haze reveals Shadow Fiend and also weakens his already low armor.

 * With armor items like  or  combined with Bash of the Deep, Slardar can easily tank the, If not dueled himself, he can drop '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.

Others

 * 's can be revealed easily by Corrosive Haze
 * 's can be interrupted with Slithereen Crush, and 's passive is useless when Slardar uses Corrosive Haze.
 * 's already low armor and easily interruptible ultimate, can make Slardar her worst nightmare.  also often builds  which is revealed by Corrosive Haze.
 * 's ultimate makes her and all her allies invisible for a duration. Corrosive Haze reveals invisibility, making  useless.
 * because Corrosive Haze has shorter cooldown than Spellblock 8 seconds (13-5).
 * Slardar's Bash of the Deep pierces Spell Immunity so Black King Bar won't prevent the Bash.

Items
