When cast, fire swirls around Signum as she generates a solid metal arrow, which she then infuses with mana until it glows, to shoot at the target. As the arrowhead has the same composition as Laevatein's blade, mana accumulated therein can be preserved for a short period of time even when the arrow is shot. Having the highest class of power and defense-penetration effect among Signum's spells, it detonates into an explosion upon impact and destroys the target with flame of ultra high heat. The command phrase is "Fly, falcon!" (Kakeyo, hayabusa!)
