Background
This thick belt has a heavy iron tube as its core. The user can't simply snap this on; he must step through the hoop and then fasten the device in place with leather straps. The belt contains a variety of reactive chemicals and mechanical devices that detect incoming physical and energy attacks, and instantly respond to shunt them aside.
