Multiattack

The automata devil makes one Bite attack, one Whip attack, and two Claw attacks. It can replace two Claw attacks with a use of Shredding Maw.

Bite

Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 18 (2d10 + 7) slashing damage.

Claw

Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 16 (2d8 + 7) slashing damage.

Whip

Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 12 (2d4 + 7) slashing damage, and the target is grappled (escape DC 17). The automata devil has two whips, each of which can grapple only one target.

Shredding Maw

One creature grappled by the automata devil is pulled up to 10 feet toward the devil's central maw, which shreds the creature with churning gears, razor teeth, and whirling blades. The target must make a DC 17 Strength saving throw, taking 36 (8d8) slashing damage on a failed save, or half as much damage on a successful one.

Teleport

The automata devil magically teleports, along with any equipment it is wearing or carrying up to 120 feet to an unoccupied space it can see.
