The grimlock is similar to a gibberling. They have a higher base level and lower AC but weaker attacks and also have no eyes. Like the gibberling, they are only notable for appearing in very large groups.
Beware, it's considered cannibalism to eat a grimlock as a human.
Yet an other Dungeons and Dragons monster. The Grimlock are primitive, savage, pale-skinned and eyeless humanoids. D&D derived them from the "morlocks" of "the time machine" by H.G. Wells.
