Goblins

From publisher blurb: Monster Brief provides a small selection of new, revised, or expanded creatures to be pitted against your players. In this offering you’ll find the beast wrangler, whose way with animals can swarm an opponent under with his bestial friends, the wolf rider who rides the mighty vargr canines into battle, and the commanding goblin lord, leader of the tribe. Also included is the ragefur mushroom, a narcotic that is poisonous to any other race, but drives goblins to a berserk rage.
