The Rock-Hide Grazer is a docile herbivore native to the vulcanic regions of Arcadia. It primarily feeds on Pyre Moss and mushrooms. Using its rocky hide it camouflages itself whenever a large predator gets near, while smaller predators have slim to no chances of getting through the natural armor of this creature.

Genetic tests and comparative analysis of its internal structures lead scholars to one conclusion: The Rock-Hide Grazer is a close relative to the Neobehemoths. Currently, it is considered to be the most primitive and basal member of this family.
