Centaur Ghast

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

Stench. Any creature that starts its turn within 5 feet of the ghast must succeed on a DC 12 Constitution saving throw or be poisoned until the start of its next turn. On a successful saving throw, the creature is immune to the ghast's Stench for 24 hours.

Turning Defiance. The ghast and any ghouls within 30 feet of it have advantage on saving throws against effects that turn undead.

Multiattack. The ghast makes one Bite attack and two Claw attacks.

Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 9 (1d6 + 6) slashing damage. If the target is a creature other than an elf or undead, it must succeed on a DC 12 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 16 (3d6 + 6) piercing damage.
