SRD:Vengeful Gaze of God

The target of this spell is subject to 305d6 points of damage (or half of that if a Fortitude save succeeds). If the target is reduced to –10 hit points or less (or a construct, object, or undead is reduced to 0 hit points), it is utterly destroyed as if disintegrated, leaving behind only a trace of fine dust. The caster is likewise dealt 200d6 points of damage
