Retractable Stinger, Advanced
This hollow stinger is installed in an armor upgrade slot. It is typically stored in a limb of the armor (though some androids use it to augment their headbutts). The stinger must be extended to be used as a weapon or to refill its injection reservoir. Extending or retracting the stinger is a move action.
