Conpedes

Magic Resistance. The devil has advantage on saving throws against spells and other magical effects.

Multiattack. Conpedes makes two attacks with its chains.

Chain. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 11 (2d6 + 4) slashing damage. The target is grappled (escape DC 17) if Conpedes isn't already grappling a creature. Until this grapple ends, the target is restrained and takes 7 (2d6) piercing damage at the start of each of its turns.

Animate Chains. Up to five chains Conpedes can see within 60 feet of it magically sprout razor-­edged barbs and animate under the devil's control, provided that the chains aren't being worn or carried.

Each animated chain is an object with AC 20, 20 hit points, resistance to piercing damage, and immunity to psychic and thunder damage. When Conpedes uses multiattack on its turn, it can use each animated chain to make one additional chain attack. An animated chain can grapple one creature of its own but can't make attacks while grappling. An animated chain reverts to its inanimate state if reduced to 0 hit points or if Conpedes is incapacitated or dies.

Unnerving Mask. When a creature Conpedes can see starts its turn within 30 feet of the devil, the devil can create the illusion that it looks like one of the creature's departed loved ones or bitter enemies. If the creature can see Conpedes, it must succeed on a DC 14 Wisdom saving throw or be frightened until the end of its turn.

Animated Chains Attack. Conpedes makes a chain attack with an animated chain.

Move. Conpedes can move up to 30 ft.

Hellish Chains (Cost 3). Conpedes targets one creature within 10 feet of a chain he controls. The target is wrapped in magical chains of fire and restrained. The restrained target takes 21 (6d6) fire damage at the start of each of its turns. At the end of its turns, the target can make a DC 17 Strength saving throw, ending the effect on itself on a success.
