Fireball

Fireball (ファイアボール, Faiabōru) is an offensive spell in fire magic that allows a mage to ignite a flame and control this flame until it sets a target on fire.

Kirche von Zerbst once used this spell in battle against Fouquet's earth golem; though it had set the golem on fire momentarily, the golem was able to fend the fires out through fanning it out with its arms.

Flame, Kirche's familiar, also used this once to blast off Manicamp, Ajax, and Gimli off the window upon Kirche's orders. However, this variant does not enable Flame to chant any incantation, being a salamander familiar.

Trivia

 * While Louise de la Vallière attempted to perform this spell using the incantation and called it fireball, Kirche von Zerbst recited the same incantation Louise had spoken, but called this spell merely as fire (ファイア, faia). Whether this is a different spell or not is unknown.
