After gathering all four of the Spirits, Ultimate Elements can be activated by Estelle once she has used all of her burst artes at least 20 times each, with the exception of the unnamed burst arte that requires her joke weapon. Once this condition has been met, the mystic arte can be used by holding the "Attack" and "Artes" buttons during any arcane, altered, or burst arte if Estelle is at Over Limit level 4. Once activated, the background changes, and Efreet, Gnome, Sylph, and Undine appear from within Estelle as colored wisps of red, brown, green, and blue, respectively, rising high into the sky.
