Death Throes

You attune your body's life force so that if you are killed, your body is instantaneously destroyed in a violent explosion of energy.

If you are killed, your body is instantaneously destroyed in an explosion that deals 1d8 points of Force damage per caster level to everyone (and everything) in a 30-foot-radius.

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.
