Grants Zethia a summon gauge and changes the shapeshift button into a summon button. Tapping this button summons Bahamut. While Bahamut is summoned, the power of certain standard attacks will be greatly increased, and Bahamut will attack automatically. After attacking a set number of times, Bahamut will automatically use the Cataclysm Beam skill.
While Bahamut is not summoned, certain standard attacks will fill the summon gauge.
Swiping to dodge during a standard attack will carry out an additional attack toward surrounding enemies, dealing 3 hits of 30% shadow damage. Performing a standard attack during this unique dodge will then resume Zethia's standard attack combo from her most recent attack (Dodging again immediately after Zethia's unique dodge will instead result in a standard dodge).
In addition, Zethia will deal 1 hit of 183% shadow damage to surrounding enemies when she dodges an attack. This attack will only activate once per dodge.
