Unlike most of the other Under Night In-Birth characters, Vatista uses FLS, and fights with the Aegis Attributor a set of six Razor Wings she can manipulate as weapons. Originally she had a seventh wing, but was used by Kuon to save Waldstein from turning into a Void in progress, as well as the creation of the Indulgence Weapons (such as the sword Insulator and daggers Eliminators) long time ago.
She also possesses the ability to manipulate light in projectiles such as beams, fireballs, short-range blasts, and explosive crystals. Unfortunately in BlazBlue: Cross Tag Battle, she lost her explosive crystal moves.
Vatista will flip jump backward into a flight state and rush towards the opponent. While the opponent is immobilized, Vatista creates an energy rune spell underneath her enemy while her wings surround them and detonate, creating an explosion.
