An Abyss Worm appears as part of the Ouranos encounter in Copperbell Mines (Hard), circling beneath the sand in the center of the room and damaging anybody on top of it. It occasionally starts searching for fodder, and if it isn't fed will suck the party to the center of the sand pit and deal massive damage to all players. This can be avoided by moving one of the Crystallized Rocks on the outer edge of the arena to the sand pit, as the worm will instead devour the rock. The Abyss Worm cannot be directly targeted by players, and will despawn upon Ouranos' defeat.
