Charge. If the Stygi moves at least 20 feet straight toward a target and hits it with a ram attack on the same turn, the target takes an extra 5 (4d6) bludgeoning damage. If the target is a creature, it must succeed a DC 13 Strength saving throw or be knocked prone.
Too Angry to die (recharges after a long rest). If a fatal hit does less than 12 damage, the Dracorex negates all of the damage.

Stygimolochs are almost always overlooked, due to the fact that they are very similar to small Pachycephalosaurus. Stygimoloch lives in the Arid southwestern regions of Arkamata, normally being found in the canyons and ridges near the Neprona Mountains, with a high concentration in the Tastatunga Valley below Kaiser's Ridge on Mount Gorepath. The tall sandstone walls of the ridge have small burrows dug by mating Stygimolochs. The Stygis are incredibly defensive and will square up to predators as large as Utahraptors. Stygis will help their kin fight predators, ganging up and ramming the same target until it goes down or retreats. And they hit hard, because they stygimoloch's head is attached differently then most animals, being in a suitable position for absorbing impacts. Despite the durability of these grunts, when the predators are Ceratosaurus sized or bigger, Stygis perform a tactical retreat and get to the nearest burrow to hide. However, most humanoids are fair fights for them, and Stygis WILL fight hard. Many people end up getting Knocked out by the constant banging of bone against body.
