Dark Magic

Dark Magic is a rare magic attribute in Black Clover that lets its user generate and manipulate darkness. It is described as the polar opposite of Light Magic and is slow, so some mages channel it through a weapon with Reinforcement Magic, as Yami Sukehiro does by coating his katana in darkness. Its slight gravitational pull draws in and absorbs other magic, and because the power of the underworld is said to dwell in it, it is effective against devils and their magic.
