Bard Longineus

Bard Longineus is the Extreme Magic of Muu Alexius' Djinn, Barbatos. It takes the form of a huge sword made of blue light which pierces through the earth. It seems to be capable of destroying faraway objects. However, its full potential is yet to be shown as the spell was interrupted halfway by Alibaba Saluja.
