AC (2 attacks) – 40 damage, and if the target is wearing metal armor, it begins to rust (save ends). Initiative: +11 (see also double initiative) Its coiled body-as long as a caravan of wagons-seems to judder from one position to the next, a trail of afterimages tracing its movement. The ground heaves upward, and out from beneath the broken stone rises a colossal two-headed worm with dull violet scales and hissing mouths wet with saliva. Numerous bands of dungeoneers have been ambushed by these brutes, the encounters forcing delvers to return to the surface unarmed and nearly nude. The two-headed rustmaw displacer purple worm is one such example, a tireless engine of devouring that blends aspects of the purple worm, the displacer beast, and the rust monster. Many of these creatures, however, are warped by the feral magic of the underworld, their already monstrous forms transmogrified into aberrant beasts unlike anything produced by the hand of nature. Through lightless tunnels, caves, and dungeons they burrow, most driven only by a primal desire to hunt, to mate, and to nest. Countless strange and terrifying creatures lurk in the subterranean world that sprawls beneath the mortal empires.
