Charge. If the pachycephalosaurus 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 5 (2d4) bludgeoning damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone. Sure-Footed. The goat has advantage on Strength and Dexterity saving throws made against effects that would knock it prone.
Ram. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) bludgeoning damage.
These herbivorous dinosaurs live in small herds, and behave much like mountain goats; roaming mountainsides, hopping from rock to rock. Males of the species can be especially aggressive, using their thick, domed skulls to ram into rival and predator alike, though they will often choose to run rather than fight. The kingdom of Wreadora has domesticated the species for use in labor, usually in the construction sector, to move heavy loads and break down walls. They're also occasionally used as mounts by dinosaur knights, ramming into enemy fortifications like a battering ram.
