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 Sivir

How to counter and exploit weaknesses

  1. Dodge her blade's return too

    Dodge Boomerang Blade (Q), then its return: it damages on the way out and on the way back, and it costs Sivir a lot of mana.

  2. Pop her shield first

    If you have CC, cast a cheap spell first, or fake a step forward: Spell Shield (E) only blocks one ability, and heals her if it blocks.

  3. Back off when she casts On The Hunt

    Back off when she casts On The Hunt (R): her whole nearby team gains move speed to engage on yours.

  4. Don't let her push alone

    Don't leave her alone on a lane for too long: with Ricochet (W), her autos bounce between minions, and your wave, then your tower, fall fast.
