Verpine droid disintegrator

An outgrowth of the droid disruptor weapons made by the Verpine and Bothans. The droid disintegrator was simply the most powerful ion rifle used and while not generally devastating against organic opponents, it was twice as deadly to droids. In addition to this, this ion weapon could bypass certain defenses that other weapons could not. The one disadvantage is that they cannot use most power packs.
