Balmung

Balmung: Phantasmal Greatsword, Felling of the Sky Demon is a two-handed, golden greatsword with a blue jewel embedded in the hilt that boasts a magnificence and enormity possible only for weapons tended to by inhuman hands. It is the holy sword of the Nibelungs, used to slay the dragon,. It is a cursed holy blade possessing the attributes of Gram, the demonic blade of its origin, so it will change attributes between holy sword and demonic sword depending on who wields it. Having accomplished the feat of dragon slaying, those with the blood of dragons will take additional damage from it.

Upon chanting "-- O sword, Let thee be filled.", he holds it above his head, and it begins to glow with an orange light. The jewel stores and preserves magic energy, true Ether, from the Age of Gods, and releasing it causes it to emanate a twilight aura. The twilight swells around the sword and is released as a flash of light, a surging wave with the simple purpose of destruction. Compared to the straight line released by Clarent Blood Arthur, it releases a wave of twilight in a semicircle that is centered around him.
