Scattered throughout the lands of Abyssea are ancient stones of great power, known as Ancient Abyssite. Each abyssite is known to grant favorable bonuses to its possessor while they travel through Abyssea, and thus can be a valuable asset for adventurers to seek and acquire. These quests will automatically flag upon checking the Cavernous Maw in the designated zones with a Traverser Stone in your inventory.
