A crude phobium emitter represented a lightsaber emitter matrix. It was constructed using Phobium, with a design focus on catering to the more forceful styles of both Jedi and Sith (potentially rendering it highly appropriate for those who utilized the fourth form of lightsaber combat). Although a phobium emitter possesses greater weight and reduced manageability compared to typical disrupting emitters, its effectiveness is generally considered to be significantly superior.
