When provided with proper rest and food, this mutation allows the character to recuperate from injury at a staggering rate. Given time, mutants may re-grow severed limbs.
The character heals 10 extra hit points per day. If he should be so unfortunate as to lose a limb or extremity (and survive), the lost body part will regenerate over a period of 1d4+2 weeks. A head may never be regrown, and characters do not regenerate from death.
