You reconnect the subject’s severed body parts (hands, feet, arms, and legs), but only if the missing limb is present during casting. Multiple limbs can be reattached with a single casting of lesser regenerate. After the spell is cast, it takes 2d10 rounds for the limb to become useful again and for the negative effects of losing the limb to end. Lesser regenerate also rids the subject of exhaustion and/or fatigue, and eliminates all nonlethal damage the subject has taken. It has no effect on nonliving creatures (including undead).
