Playing as Kha'Zix

Tips to maximize your impact

  1. Pounce on isolated targets

    Jump on an isolated target with Leap (E), then Taste Their Fear (Q): with no ally nearby, Unseen Threat (passive) marks them and the spell hits much harder.

  2. Vanish to reposition

    In teamfights, cast Void Assault (R) to vanish and reposition: the invisibility triggers Unseen Threat (passive), and your next auto damages and slows.

  3. Heal with your spike

    Detonate Void Spike (W) close to you in the jungle or in teamfights: you heal if you're inside the explosion area.

  4. Pick your evolutions well

    Pick your evolutions to fit the game: evolved Leap (E) resets on each takedown, evolved Taste Their Fear (Q) gains range and a lower cooldown on isolated targets.

Playing against Karthus

How to counter and exploit weaknesses

  1. Stay near your minions

    Stay near your minions or your allies: Lay Waste (Q) deals much more damage when the blast hits only one enemy.

  2. Jump on him if you can

    If you can engage, jump on him: Karthus has no dash or leap to escape.

  3. Don't stay low once he hits 6

    Once he hits level 6, back instead of staying at low health: Requiem (R) hits every enemy champion wherever they are, 3 seconds after he starts channeling.

  4. Save your protection for Requiem

    If you have a shield, a heal or invulnerability, save it for Requiem (R): it hits every enemy champion 3 seconds after he starts channeling.

  5. Move away after he dies

    Once Karthus is dead, move away: Death Defied (passive) keeps him in spirit form for a while, and he can still cast his spells.
