This power is not effective against
damage from starvation, thirst, or
suffocation. Also, attack forms that don't deal
hit point damage (for example, most poisons) ignore
true metabolism. You can also use this power to regrow lost portions of your body and to reattach severed limbs or body parts, if you do nothing but concentrate on regrowing the lost body part or reattaching the severed limb for the
duration of the power. You do not gain the benefits described earlier when you manifest
true metabolism for this purpose. You must have a Constitution score to gain any of this power's benefits.
