Karthus

Karthus is a champion in League of Legends (LoL).^[1]

Abilities

Death Defied

Innate: Upon taking

fatal damage, Karthus enters a zombie state for 7 seconds, during which he can cast his abilities at no cost. If Defile has been learned, it will remain toggled on for Death Defied's entire duration. Requiem becomes disabled after Death Defied has lasted 4 seconds.

While under this state, Karthus becomes

untargetable and

immune to crowd control as well as prevents all incoming damage, but is also rendered unable to move, declare basic attacks, use summoner spells, and activate items.

"I am become death!"

Disruption

Interrupted

Requiem's channel is telegraphed to all enemy champions by a beam of light that descends on all targets, including if they are untargetable or even dead.
Requiem will affect clones.
The damage will apply spell effects to targets in order of being spawned. Single target spell effects (such as Luden's Companion) are thus triggered on the leftmost champion on the loading screen.
Requiem will not affect Neeko if she's disguised as a non-champion if Karthus is affected by Death Defied.^(bug)
