Creepy Doll

False Appearance. While the creepy doll remains motionless, it is indistinguishable from an ordinary, inanimate doll.

Multiattack. The creepy doll makes one attack with its scissors and uses Psychic Assault.

Scissors. Melee Weapon Attack: +4 to hit, reach 5 ft., 1 target. Hit: 7 (2d4 + 2) slashing damage. 

Psychic Assault. The creepy doll targets one creature it can see within 30 feet of it that has a brain. The target must succeed on a DC 12 Intelligence saving throw or take 6 (1d10) psychic damage. Also on a failure, roll 3d6. If the total equals or exceeds the target's Intelligence score, the target is stunned until the end of the creepy doll's next turn.

Body Swap (Recharge 6). One humanoid that is stunned by the creepy doll's Psychic Assault attack must succeed on a DC 12 Charisma saving throw or be possessed by the creepy doll's spirit while the target's spirit is placed into the creepy doll's body. The creepy doll controls the target's body completely. It retains its alignment, intelligence, wisdom, charisma, and immunity to being charmed and frightened. It otherwise uses the possessed target's statistics, but doesn't gain access to the target's knowledge, class features, or proficiencies.

The possession lasts until the body drops to 0 hit points, the ghost ends it as a bonus action, or the ghost is turned or forced out by an effect like the dispel evil and good spell. When the possession ends, the creepy doll's spirit reappears in the doll returning the target's spirit to their body. The target is immune to this ghost's Possession for 24 hours after succeeding on the saving throw or after the possession ends.
