Pachycephalosaurus are small, slow dinosaurs that at first glance may seem lacking in the use department. However leveling one of these Cretaceous critters, especially a high level one, in Melee, Stamina and Health can turn them into the ultimate living taming mount only rivaled by a high Melee Mantis equipped with clubs, knocking out Parasaurs, Trikes, Dilos, Raptors, Pteras and more in one or two charge attacks that can down creatures far more quickly and efficiently then the average Beelzebufo or Pulmonoscorpius. Not only that but there eggs can be used to make the preferred kibble of the Paraceratherium. Meaning taming Pachys for eggs is also quite worthwhile
