Multiattack - Sweep. The acrocanthosaurus attacks twice; once with its claws, and again with its kick. The kick cannot hit the same target as the claw attack if said target is below large size.

Hacking Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 30 (2d12 + 12) piercing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 16). Until this grapple ends, the target is restrained, and the acrocanthosaurus can't bite another target.

Claws. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 20 (3d8 + 7) slashing damage. When moving along the side of a large or bigger target's space, add 12 (2d8) slashing damage.

Kick. Melee Weapon Attack: +12 to hit, reach 8 ft., one target. Hit: 18 (3d8) bludgeoning damage. The acrocanthosaurus must stop moving to use its kick, and will be knocked prone on a critical miss.

Gnaw. Failed attempts to escape the acrocanthosaurus' biting grasp allow it to deal its biting damage to the held target again, at the expense of giving the target advantage on escaping in their next attempt. Gnawed targets will be knocked prone on release.
