So say you are flying "Whisper" with VI and Advanced Cloaking Device so PS 9 and you won the initiative at the start of the game.
During the game you go toe to toe with Fenn Rau, you do some damage to Rau but hes still in the fight, so you cloak - when Rau shot's back does "Whisper" get 2 or 4 evade dice?
