Charge. If the Bull moves 10 feet before attacking an enemy, and then hits it with a gore attack on the same turn, the target takes an extra 3 (1d6) piercing damage. If the target is a creature, the creature must make a DC 14 Strength saving throw be knocked away 5 feet, and become prone. If they succeeded they are only knocked back the 5 feet.

Undead Fortitude. If damage reduces the zombie to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.

Hooves. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6+ 4) piercing damage.

Gore. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 9 (2d4 + 4) piercing damage.
