Bronze Bull

Charge. If the Bronze Bull moves at least 10 feet straight toward a target and then hits it with a gore attack on the same turn, the target takes an extra 9 (2d8) piercing damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be pushed up to 10 feet away and knocked prone.

Sure-Footed. The Bronze Bull has advantage on Strength and Dexterity saving throws made against effects that would knock it prone.

Gore. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 11 (2d4 + 6) piercing damage.

Fire Breath (Recharge 6). The Bronze Bull exhales fire in a 10-foot cone. Each creature in that area must make a DC 12 Dexterity saving throw, taking 18 (5d6) fire damage on a failed save, or half as much damage on a successful one.
