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 Master Yi

How to counter and exploit weaknesses

  1. Don't run alone from his R

    Against Highlander (R), don't run alone: regroup with your team, because he gains speed and ignores slows.

  2. CC him after his Alpha Strike

    If you have CC other than a slow, land it right after Alpha Strike (Q): during the strike, he's untargetable, and Highlander (R) ignores slows.

  3. Interrupt his Meditate

    If you have CC, interrupt Meditate (W): he channels it to heal, more at low health, and to reduce the damage he takes.

  4. Pressure his jungle early

    Put pressure on his jungle early on: Master Yi is strongest once he has his items, and each stolen camp delays him.
