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 Smolder

How to counter and exploit weaknesses

  1. Trade early

    Take your trades early: his basic spells only gain damage with the Dragon Practice (passive) stacks he builds over the game.

  2. Save your CC for his flight

    If you have hard CC, save it for Flap, Flap, Flap (E): it's his only way to escape, and hard CC interrupts his flight.

  3. Don't stay grouped

    Don't stay grouped with your allies against him: empowered, Super Scorcher Breath (Q) also damages around its target and behind it.

  4. Leave the center of the breath

    Get out of the center of MMOOOMMMM! (R): that's where the breath hits hardest and slows.
