Trobold

A Trobold is a magical hybrid of a troll and a kobold, physically resembling a kobold with multiple rows of sharp teeth. Each is a short (3 feet tall) hunched creature with rubbery gangly limbs and sharp clawed hands. A trobold will regenerate at the rate of 2 HP per round. Unlike a troll, a slain trobold regenerates so swiftly it will rise up to fight again a mere two rounds after it was killed. Only fire and acid will inflict permanent injury and death upon the hideous little creature. Furthermore, if a slashing weapon is used to slay a trobold there is a 50% chance it will result in two trobolds rising from the corpse. Trobolds attack in packs, using ambush, fiendish traps, and tricks combined with overwhelming numbers and savagery to send many a band of adventurers fleeing for their lives.
