Traits

Adhesive. The chair mimic adheres to anything that touches it. A creature grappled by the mimic has disadvantage on escape attempts.

False Appearance. While motionless, the chair mimic is indistinguishable from an ordinary wooden chair.

Mimicry. The mimic can perfectly replicate the look of a chair, making it impossible to detect without magical means or a successful DC 18 Investigation check.

Actions

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target.
Hit: 1d8 + 2 piercing damage. The target is grappled (escape DC 12). Until this grapple ends, the target is restrained.

Latching Grip. Melee Weapon Attack: +4 to hit, reach 5 ft., one target.
Hit: 1d6 + 2 bludgeoning damage and the target is restrained until they break free. If the mimic already has a creature grappled, it gains advantage on its bite attack.
