Narsk Ka'hane, a Bothan spy, carried a needler with him, which was ideal for spy missions as it did not make the loud noise of a blaster. Narsk was able to switch the setting on his needler to fire acid-filled darts or pulse-wave darts. Narsk used this weapon during his initial encounter with Jedi Knight Kerra Holt at the Daimanate Dynamic Testing Facility without success.
Imperial spy Tanya Madera used this weapon to administer the deadly triflexia virus to both Chief Technician Adonar Dellox and one of the X-wing pilots on Reginard Base. She later used the weapon to defend herself against a group of Rebels, though she had only five shots left.
