Regenerate

7th-Level Necromancy
Casting Time: 1 minute
Range: Touch
Components: VSM (a prayer wheel and holy water)
Duration: 1 hour

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 start of each of its turns (10 hit points each minute). If you hold a severed body part to where it attaches stump, the spell instantaneously causes the appendage to reattach.

Any other severed body part (fingers, legs, tails, eyes, and so on), if any, attempt to regrow after 2 minutes. Make a spellcasting ability check for each body part (the DC varies based on the injury.) On a successful check, the body part regrows in perfect condition, but on a failed save, the body rejects the magic, and this spell cannot be used to attempt to regrow that body part again.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the target regains an additional hit point at the start of each of its turns for each slot level above 7th.
