Gruoks are wild animals similar in appearance to Wild Pigs and are often referred to in game as pigs or piggies. Young Gruoks are called grulets and are often grouped with Gruok sows. The higher level gruoks tend to be very aggressive with attacks such as the Bleed line. Strangely, all gruoks seem to drop coin. They also frequently drop hides as well as trophies, technical components, formulas, and hoard items.
Once killed, Gruoks can be harvested for hide and meat.
