A green stab to an unarmored torso is death, and a stab to a hand, foot or limb renders it useless. A stabbed arm should hang limply at the side, though you can use it to block. A stabbed leg puts you on your knees. Black is a classification that seems to only be present in Anfalas. Like green, it is added on top of either red, or blue.
Black weapons are mass weapons, axes, hammers, or maces.
Their damage relies on the weight of their head to inflict damage. The black classification means that a weapon ignores armor. Now, so far we've only talked about killing, but there are several types of protection, namely armor and shields. Anfalas is currently using the national rules for armor and shields with the addition of black weapons ignoring armor. Shields are padded, rigid, objects with handles that are used to block, and are specifically designed and built for that purpose.
