Kha'Zix's abilities

Passive, spells and ultimate

Unseen Threat (P)

Nearby enemies that are Isolated from their allies are marked. Kha'Zix's abilities have interactions with Isolated targets.When Kha'Zix is not visible to the enemy team, he gains Unseen Threat, causing his next basic attack against an enemy champion to deal bonus magic damage and slow them for a few seconds.

Playing as Karthus

Tips to maximize your impact

  1. Aim for isolated champions

    Aim Lay Waste (Q) at a champion away from their minions: if the blast hits only one enemy, it deals much more damage.

  2. Wall before your combo

    Place Wall of Pain (W) in their path before your combo: anyone who crosses it is slowed and loses magic resist.

  3. Keep playing after you die

    After you die, keep casting your spells: Death Defied (passive) keeps you in spirit form for a while, and you can still cast Lay Waste (Q) and Requiem (R).

  4. Requiem for the finish

    Save Requiem (R) to finish off wounded enemies, often right after a teamfight: it hits every enemy champion wherever they are, after a 3-second channel.

Playing against Kha'Zix

How to counter and exploit weaknesses

  1. Stay near an ally

    Stay near an ally: alone, Unseen Threat (passive) marks you as isolated, and Taste Their Fear (Q) hits you much harder.

  2. Fight back if his leap misses

    If he leaps in without a kill, fight back: Leap (E) has a 20 to 12 second cooldown, which a takedown only resets once the spell is evolved.

  3. Ward his paths

    Ward his paths: out of sight, Unseen Threat (passive) empowers his next auto against a champion, which damages and slows.
