Centaur Devourer

Charge. If the centaur moves at least 30 feet straight toward a target and then hits it with a pike attack on the same turn, the target takes an extra 10 (3d6) piercing damage.

Multiattack. The centaur makes two attacks: one with its hooves and one with its bite or two with its hooves.

Pike. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 9 (1d10 + 4) piercing damage

Hooves. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (1d10 + 2) piercing damage plus 5 (1d10)poison damage, and the target is grappled (escape DC 13). Until this grapple ends, the target is restrained, and the centaur can't bite another target.

Swallow. The centaur makes one bite attack against a Medium or smaller target it is grappling. If the attack hits, the target is swallowed, and the grapple ends. The swallowed target is blinded and restrained, it has total cover against attacks and other effects outside the centaur, and it takes 10 (3d6) acid damage at the start of each of the centaur's turns. The centaur can have only one target swallowed at a time. If the centaur dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 5 feet of movement, exiting prone.
