What is a pachy used for? pachy battling strategies in ARK: Survival Ascended & Evolved.
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
Pachy has the earliest unlockable land dino saddle and a useful charging attack that can knock a dino out.Which makes it a good mount for early to mid game but this charging attack does not exist on mobile i tried it myself with swipe down/up, alternate attack 1, and 2 but it does not work and because of that this dino is not useful at all.
Pachy Usefulness Rating(Mobile): 1/10
The Pachycephalosaurus' neck was not built for a forward headbutt, but when you consider a strike similar to giraffes, the skull's shape is ideal. The bony ridges and knobs at the back of the skull would deal no damage in a forward strike, but indeed be useful in side-strikes to the flank of an opposing dinosaur, likely of an entirely different species.
