Metallic Dice are six-sided die made either created by a metal-smith or a Steel Release user. Aside from being used in gambling games, their main purpose is to be used as projectiles in Magnet Release techniques. The dice are made of a metal that can be infused with chakra, potentially increasing the devastation that they can cause. Because they are dice, it is easy to smuggle these projectiles into areas where weapons cannot be brought, making these a weapon of choice for assassins possessing the Magnet Release kekkei genkai.
