As the killing blow falls, you smile with grim satisfaction even as the light of life fades, knowing that your enemy will soon be joining you in the afterlife.

If you are killed, your body is instantaneously destroyed in an explosion that deals 1d8 points of damage per caster level to everyone in a 30-foot-radius burst.
This explosion destroys your body, preventing any form of raising or resurrection that requires part of the corpse. A wish, miracle, or true resurrection spell can restore life.
