Cursed Mannequin

False Appearance. While the Mannequin remains motionless, it is indistinguishable from an inanimate mannequin.

Innate Display Piece: While being observed the Mannequin remains in a petrified condition.

Attacks made against other creatures while not breaking sight with the mannequin are made at disadvantage.

Creaking Touch. Once per round on a successful hit, the foul enchantments that imbue the Mannequin seep through their limbs and try to infect the target.

DC 14 Constitution saving throw. If the saving throw fails by 5 or more, the creature is instantly petrified in wood. Otherwise, a creature that fails the save begins to turn into a static mannequin and is restrained. The restrained creature must repeat the saving throw at the end of its next turn, becoming petrified in wood on a failure or ending the effect on a success.

The wooden petrification lasts until the creature is freed by the greater restoration spell or other magic.

Can’t Blink. If 3 or more mannequins gather within 5ft of each other, as a joint action they may cast the spell Darkness. One of the contributing mannequins becomes the source of the Darkness.

Pack Tactics. The Mannequin has advantage on attack rolls against a creature if at least one of its allies is within 5 feet of the creature and the ally isn't incapacitated.

Multiattack. The Mannequin makes slam two attacks with it's limbs.

Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., 1 target. Hit: 5 (1d6 + 2) [bludgeoning] damage. 

Windows to the Soul. When a creature is petrified the eyes become glass spheres. The Mannequin may use a bonus action to remove one eye, DC 15 Sleight of Hand, from a petrified creature. Should the both eyes be removed from the petrified creature, the sockets and head smooth out and the creature becomes an additional Cursed Mannequin. This can only be reversed by a Wish spell.

• Sleight of hand check is made at disadvantage during combat.

Soul Seed. Once removed, the glass eyes merge into a single clear spherical gem termed the “Soul Seed”. Whoever possesses the gem, as a bonus action, can command the mannequin it came from, if in the possession of another mannequin the possessor’s command carry over to the new mannequin. If the gem is destroyed the mannequin becomes inert, but will lash out at entities that come within 10ft in an attempt to expand their numbers.

Dash. If more than 5ft from the nearest creature, the Mannequin will dash as a reaction the moment it is unobserved.

Attack of opportunity. If within 5ft of a creature the Mannequin with attack as a reaction the moment it is unobserved
