Death Defied

Upon taking fatal damage, Karthus remains active for 7 seconds, rendering himself unable to move, attack, or use item actives/passives, but becoming untargetable and invulnerable for the duration as well as being able to use abilities at no cost.

If Defile Defile has been learned, it will remain toggled on for Death Defied's entire duration.

Additional Information:

  • Death Defied will always trigger after revival effects (Guardian Angel item Guardian Angel, Chronoshift Chronoshift) and if Karthus is killed by the Nexus Obelisk.
