One of the pilots noticed how their shots had no effect while the vampire was amusing itself but when it wanted to do damage it had to be tangible otherwise it'd be a whole other effect, that could explains its necromantic powers. The pilot swooped dangerously close to the TIE Defender being havoced by the vampire, if the vampire had not been there it would of been a betrasive maneuver- as they were taught at the Naval Academy. A maneuver just such for an occasion of five against two.
