Stunner

Stunners were small, hand-held weapons used to temporarily paralyze opponents. They were capable of causing minimal, non-lethal damage to an intended target. A small thong was attached to the device, which could be wrapped around the user's hand with the disk itself placed upon the palm. By activating the power cell, the wearer could discharge a field of energy emanating from an aperture within the center of the disk. Targets within range of the weapon fell immediately unconscious upon being struck by the energy charge. Visually, the stun effect resembled the spherical rings of energy, discharged from an E-11 blaster rifle.
