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 Aurelion Sol

How to counter and exploit weaknesses

  1. Stay behind your minions

    Stay behind your minions: Breath of Light (Q) hits the first enemy in its path, and only the seconds spent on a champion give him Stardust.

  2. Play hard early

    Play hard early and don't let the game drag on: with Cosmic Creator (passive), each of Aurelion Sol's abilities grows permanently stronger through Stardust.

  3. Get out of the black hole fast

    Leave Singularity (E) quickly: it pulls you toward its center, where it executes enemies below a health threshold, and each second inside gives him Stardust.
