Gravity Core (重力の鎗 Gurabiti Koa) is a form of the Magic Spear: Ten Commandments.
The shape of the Ten Commandments' head changes to a spear possessing a long, dark blade. The lower section of the head indents in and juts back out as it reaches the point. The dark-colored blade is being supported by a thick, dark orb, which holds an intricate design covering most of the orb's surface, and, around the orb, two dark tubes connect to the blade, with two silver dots on the lower area of either tube.
