Karthus Abilities

P

Death Defied

Upon dying, Karthus enters a spirit form that allows him to continue casting spells.

Q

Lay Waste

Karthus unleashes a delayed blast at a location, dealing damage to nearby enemies.

W

Wall of Pain

Karthus creates a passable screen of leeching energy. Any enemy units that walk through the screen have their Movement Speed and Magic Resist reduced for a period.

E

Defile

Karthus passively steals energy from his victims, gaining Mana on each kill. Alternatively, Karthus can surround himself in the souls of his prey, dealing damage to nearby enemies, but quickly draining his own mana.

R

Requiem

After channeling for 3 seconds, Karthus deals damage to all enemy champions.
