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.
