A sub-species of the Behemoth that has adapted to the environmental conditions of the Forest, the Mosscloak Behemoth has developed a resistance to the poisonous mushrooms it consumes. That very poison gets stuck in its multiplying fangs and large paws, and can likely spread the poison with its attacks.

The Mosscloak Behemoth is the parent of the Sylvan Mauler, recognizable for its singularly large horns. The bushes and other foliage caught in the creature's horns inadvertently help it better conceal itself when on the hunt. Judging by the damage to the trunks of trees near the Mosscloak Behemoth's habitat, this variety appears to have incorporated the flora as part of either its territory marking or mating ritual. Rubbing against hard bark has hardened the creature's skin further. While this has made the creature somewhat sclerotic in its movements, it is still able to muster the strength to charge and leap.
