Best dino in ark in my opinion. It can deal up to 1700 or more damage per hit depending how much melee you put on it. It kills rexes, brontos, gigas and all alphas really easily and safely. It harvests great and is fast too. Broken if you ask me.
These guys have pretty low health once tou tame them (on Xbox, at least.) So, once you finally tame one, be sure to upgrade their health and stamina because it's pretty horrible at first. Also, you can't upgrade their speed, so I suggest taming a higher level griffin if you want a faster mount.
