Amputate

An extreme measure which can heal people at the cost of losing a damaged part of themselves. Target a willing creature. You harmlessly remove a limb. The removal is painless and with restoration magic the body quickly closes any open wound left. The creature heals 3d10 + your spell casting modifier (minimum of 1) and then is cured of a number of known diseases and poisons up to your spell casting modifier (minimum of 1) and regains consciousness. If the creature had its maximum hit points reduced, it has its original maximum hit points restored even if they were reduced to 0 and the creature can’t be prevented from being healed until the end of the next round. Unless the spell restores a creature's maximum hit points the creature regrows it’s limb after 24 hours and has completed a long rest.  If the body part has a cursed item that is held or worn, such as a ring the curse is removed from the individual and attunement ends unless willingly made again. This spell has no effect on constructs or undead.
