Charge. If the zombie goat moves at least 20 feet straight toward a target and then hits it with a ram attack on the same turn, the target takes an extra 2 (1d4) bludgeoning damage. If the target is a creature, it must succeed on a DC 10 Strength saving throw or be knocked prone.

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

Undead Fortitude. If damage reduces the zombie goat 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 goat drops to 1 hit point instead.

Ram. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) bludgeoning damage.
