Aetheria are equippable items that provide a primary set bonus, enhancing a variety of things, and secondary "surge" ability, that at random times, dramatically improves the wielder or penalizes the opponent for a short duration. Unlike other magical items in the game, Aetheria's power is based upon a "level" system where the Aetheria starts at level 0 and levels up to a maximum level indicated by the icon. The higher the level, the more powerful the enhancement. Aetheria is found on monsters and in chests as Coalesced Aetheria, which must be "revealed" first before being equipped by using an Aetheria Mana Stone from the Aetheria Quest. When a character is created, initially he or she cannot wield any Aetheria. See the Aetheria Quest for details for opening the slots.
