Release Notes 06/12

When Karthus dies, he can continue to cast spells for 10 seconds after death. If he kills a champion in this time he respawns instantly at base.

Karthus leaves a time delayed mine which deals double damage if it only hits a single target.

Stretches a perpendicular wall through the target location, enemies who walk through it are slowed and take increased damage.

While toggled on, Defile continually damages nearby enemies. While off, Karthus regains mana whenever he kills a unit.

Channeling spell, upon successful cast Karthus damages all enemy champions in the game.
