After dealing a Wound or a critical hit to the 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). \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The molting yawning maw makes two attacks, one with its bite and one with its tail. Or it makes two Hurl Fangs attacks. \n'b'  Bite .  Melee Weapon Attack : +6 to hit, reach 10 ft., one creature.  Hit : 6 (1d4 + 4) bludgeoning damage plus 6 (1d12) poison damage, and the target must succeed on a DC 14  Constitution  saving throw or be  poisoned  until the end of its next turn. \n'b'  Hurl Fangs .

Melee Weapon Attack : +6 to hit, reach 15 ft., one creature.  Hit : 7 (1d6 + 4) bludgeoning damage, and the target must succeed on a DC 14  Strength  saving throw or be knocked  prone . When molting, the yawning maw\xe2\x80\x99s scales grow dull and fall off. Then, the creature seeks out narrow corridors where it rubs itself against the walls to shed quicker. But to think that the creature is deprived of its  freedom of movement , making it open to  attack , is to strongly underestimate its capacity to dig into the rock to escape\xe2\x80\xa6 before coming back to catch its attacker from behind! \n'b'  Regenerate . The yawning maw regains 10  hit points  at the start of its turn if it has at least 1 hit point. \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack .

Ranged Weapon Attack : +5 to hit, range 50/200 ft., one creature.  Hit : 5 (1d8 + 1) piercing damage, and the target must succeed on a DC 16  Constitution  saving throw, taking 19 (3d12) poison damage on a failure, or half as much damage on a success. \n'b'  Tail .

The yawning maw can use its Hurl Fangs  attack  against a creature that moves within 50 ft of it. \n'b'\n'b' ABOUT \n'b' 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\xe2\x80\x94with 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. \n'b' 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.'
