Corpselight

Corpses. When first encountered, a corpselight contains the corpses of 1d6 + 3 humanoids. A corpselight can hold the remains of up to nine dead humanoids. These remains have total cover against attacks and other effects outside the corpselight. If the corpselight dies, the corpses within it can be pulled free, although they are likely not to be intact apart from the arms unless they were recently consumed. 

• The corpselight digests one humanoid corpse in its body and instantly regains 11 (2d10) hit points. Nothing of the digested body remains. if the corpse had any non-organic equipment this can be retrieved once the creature has died. organic items such as leather armour are digested.
• The corpselight animates one dead humanoid within 10 feet of itself. the zombie will attempt to climb into the corpselight and will only attack if something tries to prevent it from doing so. if it is killed before it can climb in, it cannot be reanimated again. it will act directly after the corpselight in the intuitive order

Stench of Death. Each creature that starts its turn within 10 feet of the corpselight must make a DC 14 Constitution saving throw, unless the creature is a construct or undead. On a failed save, the creature is incapacitated  until the end of the turn. Creatures that are immune to poison damage or the poisoned condition automatically succeed on this saving throw. On a successful save, the creature is immune to the stench of all corpselights for 24 hours.

Multiattack. The corpselight makes up to 4 melee attacks. If the arm making the attack is holding a weapon, this will be used.
