Regeneration

You touch a creature and stimulate its natural healing ability. The target regains 4d8 + 15 hit points. For the duration of the spell, the target regains 1 hit point at the beginning of each of its turns (10 hit points per minute).

Limbs amputated from the target’s body (fingers, legs, tail, and so on), if any, are restored after 2 minutes. If you have the amputated body part and hold it on the stump, the spell instantly causes the limb to connect.
