SPECIAL TRAITS

• Corrosive Fluids. After dealing a Wound or a critical hit to the molting yawning maw, the melee weapon or ammunition used is covered in corrosive fluids. Any non-magical weapon or armor under this effect, and which is not protected by an appropriate forging technique (such as dwarven forging), becomes fragile (see Adventurers, Equipment, Armory: Damaged Weapons and Armor).

ABOUT

The yawning maw is a huge, blind worm with glistening red scales. Its head is but a gaping mouth layered with several rows of serrated, tapered teeth. The creature can hurl its teeth at its targets with rare violence—with the missing fangs immediately replaced by the next rows. It roams tirelessly through the corridors of the Netherworld, always on the lookout for prey, which it locates by the vibrations it emits.

However, this monster suffers from an exploitable flaw: due to its rapid metabolism, it molts at least once a month, which considerably weakens its natural armor of scales.
