When activated, the party is taken underwater to a sea basin as they are then pelted with splashes and streaks of water. The camera then zooms above them to what appears to be a sphere. Aquarius Sphere originally appears in Tales of Rebirth, in which it is used as the signature attack for Shaorune, the Sacred Beast who tests the party in battle as a trial for Veigue Lungberg. Aquarius Sphere can be used by the party as the first of several extensions that appear after using the Fusionic Force Finality Dual the Sun.
