The Nullifier is an item purchasable at the Main Shop, under Magical. However, it requires an item from the Secret Shop to be completed.


Dispels the target for 5 seconds. Anytime the dispelled target is attacked, it will be slowed by 80% for 0.5 seconds.
Cast Range: 900
Movement Speed Slow: 80%
Slow Duration: 0.5
Duration: 5
Cooldown: 11
Mana: 75
Debuff Nullifier: Dispellable with any dispel.
Debuff Nullifier Slow: Dispellable with any dispel.


  • The projectile travels at a speed of 750.
  • Applies a basic dispel on the target upon projectile hit and on every 0.2s intervals along the debuff duration.
  • Nullifier first applies the dispel, then the debuff.
  • The slow immediately triggers on the target upon projectile hit as well, so that it gets slowed on hit.
    • When the target already has the Nullify debuff, refreshing it with a new cast does not trigger the slow.
  • After that, the slow triggers on every successful attack hitting the target. This means missed attacks do not trigger it.
    • The slow does not trigger when the target turns ethereal before attack projectiles hit it.
  • The slow has no trigger cooldown, so that the target can get slowed for the whole duration if it gets hit by an attack at least once every 0.5 seconds.
  • Can be cast on invulnerable units, applying the dispel and the debuff if the invulnerability can be dispelled.
    • However, if the invulnerability cannot be dispelled, the debuff cannot be applied, but can be refreshed, if already debuffed.

Recommended heroes[edit]

Arc Warden icon.png

Clinkz icon.png
  • Nullify combined with Strafe will trigger the slow with almost no interruptions.
Riki icon.png
Slark icon.png

Troll Warlord icon.png
  • Troll Warlord's high attack speed will guarantee many procs of slow on Nullifed enemies.
  • Nullifier disables counter items against Troll, such as Ghost Scepter icon.png Ghost Scepter or Ethereal Blade icon.png Ethereal Blade.
Venomancer icon.png
  • Venomancer slows keeps Nullified enemies slowed, and makes it harder for targets to escape.
Viper icon.png
  • Viper's slowing debuff keeps Nullified enemies permanently stick to the ground, and makes it harder for targets to escape.
Witch Doctor icon.png
  • A carry Witch Doctor can continuously trigger the movement slow with the fast attack speed of the Death Ward to keep the enemy in his attack range.
