Extract Brain. Melee Weapon Attack: +7 to hit, reach 5 ft., one incapacitated humanoid grappled by the ceremorph. Hit: 55 (10d10) piercing damage. If this damage reduces the target to 0 hit points, the ceremorph kills the target by extracting and devouring its brain.

Each creature in that area must succeed on a DC 15 Intelligence saving throw or take 22 (4d8 + 4) psychic damage and be stunned for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
