Ychen Bannog

Ever-Sharp Horns. The ychen bannog deals triple damage dice when it scores a critical hit with a gore attack.

Overrun. When the ychen bannog takes the Dash action, it can move through the space of a Large or smaller creature, treating the creature's space as difficult terrain. As it moves through the creature's space, the ychen bannog can make a stomp attack as a bonus action.

Peaceful Creature. The ychen bannog abhors combat and flees from it if possible. If unable to flee, the ychen bannog can attack a foe or obstacle to clear a path to safety. As an action, a driver or handler mounted on the ychen bannog or adjacent to it can make a DC 16 Wisdom (Animal Handling) check. On a success, the ychen bannog moves and attacks as directed by the driver. On a failure, the beast flees. The driver or handler must have proficiency in Animal Handling to attempt this check.

Multiattack. The ychen bannog makes one gore attack and one stomp attack.

Gore. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 27 (4d8 + 9) piercing damage.

Stomp. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 31 (4d10 + 9) bludgeoning damage. If the target is a creature, it must succeed on a DC 21 Strength saving throw or be knocked prone.

Destroying Bellow (Recharge 5-6). The ychen bannog delivers a fearsome bellow that can be heard up to ten miles away. Structures and unattended objects in a 60-foot cone take 55 (10d10) thunder damage. Creatures in the cone take 27 (5d10) thunder damage and are deafened for 1 hour, or take half damage and aren't deafened with a successful DC 18 Constitution saving throw.
