Slark/Counters

Bad against...

 * Ancient Apparition's doesn't allow to regenerate hit points, cancelling out 's passive.


 * Bloodseeker's makes Slark visible while at low health, cancelling out 's passive. Additionally,  cannot be purged by, and using  while affected by it will cause you to take damage.


 * During, Slark cannot be hit by targeted spells. However, both and  are not targeted, and can still hit Slark. Additionally,  can only remove one.
 * Even Slark has build Black King Bar, Geostrike still effects Slark.


 * Anti-Mage is the most solid counter to Slark, because he can take advantage of each and every one of his weaknesses.
 * Slark is a heavy mana reliant hero, who doesn't build mana regen items. Anti-Mage can drain all of his mana with Mana Break, and leave him vulnerable to disables, while also shutting down his escape with Pounce and Shadow Blade
 * Anti-Mage's high magical damage resistance makes Slark's nukes deal minimal damage. Slark relies on his burst damage to snowball onto lategame.
 * If Slark pounces onto Anti-Mage, he can just blink away to safety. Slark relies heavily on staying onto targets to gain Essence Shift stacks. Anti-Mage will only fight a Slark when he knows he can take him down.
 * Slark's item builds revolves around Stat Items, like Eye Of Skadi and Silver Edge, which give Slark a large mana pool. After draining his mana, Anti-Mage can then cast Mana Void to deal heavy damage and instantly kill him.


 * Both and  can hit Slark during, the latter requiring a unit nearby for the ability to be cast on. Additionally, Slark has very low health in the early game, making him susceptible to the burst from.


 * Another solid counter to Slark, paired with, Axe's forces Slark to attack him, even during . This can be effective as both  and  are not targeted, the latter dealing pure damage which Slark is weak against. Finally,  can finish off a low health Slark.

In the laning stage, Slark can't get close to (let alone initiate on) Techies without fear of being killed by a and  due to Slark's unimpressive health and armor. It's also worth noting all of Techies' abilities are AoE and thus all affect Slark during.

Others

 * Heroes with AoE abilities work greatly against.
 * will keep with him inside the  and damage him with his AoE abilities. Trying to escape the Cogs will remove mana and deal more damage to.
 * 's ultimate,, will nearly nullify (with exceptions of his auto attacks and itens), as it will silence him, preventing him from dispelling debuffs from himself, escaping, regenerating his health and becoming invisible. Its an AoE DOTS (damage over the time) silence, so there's no way to escape it, specially if used along with.

Good against...

 * Slark's rips through  charges. Additionally, Slark can  and still damage Templar Assassin while she is stealthed, since she is unable to move during.


 * Slark's can purge the  debuff. Additionally, Bounty Hunter's low health makes him weak to Slark's damage.


 * Slark is not revealed by and also does not take the percent damage from  while under the effect of.


 * Drow Ranger places heavy dependancy on the enemy being incapable of getting close to her, but with a Shadow Blade/Silver Edge and/or Blink Dagger coupled with Slark's naturally high mobility, makes him nearly impossible to keep at bay. Aditionally, makes her incapable of acting out against you in any way excluding the silence of gust, leaving her at your mercy.


 * is a simple stun that has high delay and cannot be applied to a single target twice during a single casting, making it an extremely easy spell to dodge with . Medusa cannot chase Slark in any way and has no disable beyond her ultimate, making her unable to stop him getting away and regening before coming back to finish her off. Additionally, removes -1 of every attribute, allowing him to lower her mana pool's cap and leaving her much more vulnerable in prolongued fights.

Others

 * Any hero with little lockdown, especially non-targetted lockdown, and low mobility will suffer against Slark.
 * Due to Slark's high mobility and pick off potential, he is particularly good at getting rid of supports before fights break out, allowing his team to start with an advantage.

Works well with...

 * Storm Hammer and Pounce can start initiating both.


 * Pit of Malice makes easy Pounce for Slark.
 * Invisible Slark and Underlord who travel with Dark Rift can make surprise to any enemy.
