Bodybound

Unkillable. When the Bodybound is brought to 0 hit points, instead of dying, it regains 1d12+2 hit points, and falls prone, unless it is brought to 0 hit points by taking at least 30 damage that is from a magical weapon or a spell.

Decayed Weapon. Melee Weapon Attack: +3 to hit, reach 5 ft., 1 target. Hit:4  (1d6 + 1) [slashing/piercing/bludgeoning] damage. 

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., 1 target. Hit: 3 (1d4 + 1) piercing damage. The Bodybound recovers hit points equal to the damage dealt by this attack.

Feast. The Bodybound can take a bite of uncooked meat that is no more than 24 hours old, in order to take this action, it must be holding, or have within 5 feet of it, this uncooked meat. taking this action consumes 1/2 lb of meat, and causes the bodybound to regain 2d4+6 hit points, and rebuilds any lost or broken body parts. If a Bodybound has not taken this action in the past 24 hours, it gains one level of exhaustion. If the Bodybound consumes more than 100 lbs of meat in a single 24 hour period, it becomes a [Bloated Bodybound] (see Bloated Bodybound statblock).

Reattach Limb. If one of the Bodybound's arms or legs is removed via slashing damage, it can reattach it as a reaction, as long as this reaction is used instantly after the limb is removed.
