When a regenerate spell is cast, body members (fingers, toes, hands, feet, arms, legs, tails, or even the heads of multitheaded creatures), bones, or organs will grow back. The process of regeneration requires but 1 round if the member(s) severed is (are) present and touching the creature, 2-8 turns otherwise. The reverse, wither, causes the member or organ touched to shrivel and cease functioning in 1 round, dropping off into dust in 2-8 turns. As is usual, creatures must be touched in order to have harmful effect occur. The material components of this spell are a prayer device and holy/unholy water.
