[Source] The "Phoenix II" was a plasma disruptor manufactured by Drever Corporation as a tool used by custom agents and special forces commandos to breach locked doors, such as airlocks and possibly even blast doors. While the equipment itself did well to serve its purpose, many soldiers wielded it against battle droids that they encountered after discovering its usefulness as an electrical weapon. This improvisation prompted the creation of the "DN bolt caster" that was widely used by clone pilots during the Clone Wars.
