Crush. Melee Attack Roll: +5, reach 5 ft. Hit: 6 (1d6 + 3) Bludgeoning damage, and the ??? attaches to the target. If the target is a Medium or smaller creature and the darkmantle had Advantage on the attack roll, it covers the target, which has the Blinded condition and is suffocating while the ??? is attached in this way.

While attached to a target, the ??? can attack only the target but has Advantage on its attack rolls. Its Speed becomes 0, it can’t benefit from any bonus to its Speed, and it moves with the target.

A creature can take an action to try to detach the ??? from itself, doing so with a successful DC 10 Strength (Athletics) check. On its turn, the ??? can detach itself by using 5 feet of movement.

Darkness Aura (1/Day). Magical Darkness fills a 15-foot Emanation originating from the ???. This effect lasts while the ??? maintains Concentration on it, up to 10 minutes. Darkvision can’t penetrate this area, and no light can illuminate it.

 Explode the ??? Explodes doing 2d4 bludgeoning damage
