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
