Debilitating Word

You speak a word of arcane hatred meant to mutilate the bodice of thine enemies. You choose a creature with in range and cause it to roll five constitution saving throws. For every failed save the creature or person loses a limb with the head always being the last limb to go. This spell does not function on celestial, undead, aberrations, or constructs. If the creature lacks limbs, it instead loses something of equal importance to its vital systems. The removed limbs or other parts cannot be regenerated except by means of a greater restoration spell or similar magic. If a creature's head is removed, they die outright in one round. The removed limbs appear or fall to spaces within 5 feet of the victim and rot away beyond any recognition or salvageable state so as to be useless in any necromancy or healing attempted.
