The fearsome molydeus speaks for the demon lord it serves and enforces its master's will. This demon is 12 feet tall, and its bipedal body has a slavering wolfs head and a fanged serpent's head. Its demon lord can speak and see through the serpent head; this master also uses the molydeus to guard treasures, slay foes, and terrify troops into obedience.
A molydeus' demon lord bestows on it a powerful weapon that dissolves if the molydeus dies. The weapon's form varies depending on the creator, but that doesn't affect the weapon's capabilities.
