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 Seraphine

How to counter and exploit weaknesses

  1. Dodge her Beat Drop

    Dodge Beat Drop (E), especially if you're already slowed: it roots a slowed target and stuns an immobilized one.

  2. Back off before her third spell

    Count her basic spells and back off before the third: Stage Presence (passive) casts it twice, whether it damages, slows or shields.

  3. Spread out from your allies

    Spread out from your allies against Encore (R): each champion hit extends its range, and a charmed ally near you lets it reach you.

  4. Target her: she has no dash

    If you can engage, target Seraphine: her kit has no dash to escape.
