Al-Qaus

Al-Qaus (黒磁槍 （アル・カウス）, Aru.Kausu, Black Magnet Spear) is the Dark Metal Vessel of Dunya Musta'sim. It uses Lightning Magic to use the magnetism to collect sand and rocks to attack. She can change the shape of the spear to any weapon she chooses, as long as she collects enough sand around it. She can summon earth spikes from the ground, and create Rock Dragons to attack and crush the enemy.
