Pistol
For those needing the ultimate in discretion, a wrist blaster provides protection without drawing attention. It is popular with assassins, diplomats working in hostile territories, and other VIPs who hate being completely unarmed. The wrist blaster is worn as a bracelet and looks like an ordinary piece of jewelry. The bulk of the wrist blaster contains the power cell, which is powerful enough to deliver the same damage as a blaster, but contains enough energy for only a single shot. A wrist blaster is meant for use in close quarters. Special alloys mask the wrist blaster from sensor scans for weapons. Detecting a wrist blaster with a sensor scan requires a DC 25 Use Computer check.
