The subject's severed body members (fingers, toes, hands, feet, arms, legs, tails, or even heads of multi-headed creatures), broken bones, and ruined organs grow back. After the spell is cast, the physical regeneration is complete in 1 round if the severed members are present and touching the creature. It takes 2d10 rounds otherwise.

Regenerate also cures 4d8 points of damage + 1 point per caster level (maximum +35), rids the subject of exhaustion and fatigue, and eliminates all nonlethal damage the subject has taken. It has no effect on nonliving creatures (including undead).
