Coffer Corpse

False Death. If the coffer corpse is struck by a single melee weapon attack that deals 15 or more bludgeoning, piercing, or slashing damage (before calculating damage resistances), the coffer corpse falls prone and is stunned until the end of its next turn. While stunned in this way, the coffer corpse appears to have been slain. Upon recovering from the stunned condition, its sudden reanimation causes any creature that can see it to succeed on a DC14 Wisdom saving throw or become frightened of it for one minute.

Any creature the coffer corpse is grappling when it becomes stunned also falls prone and is still grappled.

Final Death. If the coffer corpse is targeted by a ceremony spell and a Funeral Rite is chosen, the spell’s casting time is reduced to 1 minute and, upon completion, the coffer corpse is destroyed and its soul is laid to rest.

Reanimation. When the coffer corpse's body is destroyed by any means other than a ceremony spell, its soul lingers. After 24 hours, the body reincorporates at the site of its incomplete funeral rite and the soul reanimates it, restoring all its hit points. This reanimation causes any creature that can see it to succeed on a DC14 Wisdom saving throw or become frightened of it for one minute.

Strangle. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage. If the target is a Large or smaller creature, it is grappled (escape DC 15). Until this grapple ends, the target is restrained and can't breathe or speak, and the coffer corpse can't use this attack on another target. A grappled creature attempting to escape this grapple must use a Strength (Athletics) check for the attempt. An adjacent creature other than the grappled creature may use its action to make a DC 15 Strength (Athletics) check to break the coffer corpse’s grip on its victim, ending the grapple on a success.
