Okay, so I have no idea how out of date this is, because I've been travelling and haven't paid much attention to anything. Back now, and thought of an idea. It's expensive, it's a little gimmicky, it's extremely effective at what it intends to do.
Knave Squadron Pilot (27)
Flechette Torpedoes (2)
Accuracy Corrector (3)
R3-A2 (2)
Munitions Failsafe (1)
Total: 35
So again, very expensive. However, this slams ships with 4 or less hull (the ships most likely to be wanting to avoid stress) with 2 stress, guaranteed, at the cost of one stress on the E-Wing. Easily rectified next turn and likely hitting with his 3 dice primary.
Just so everyone understands what's going on here, Accuracy Corrector cancels your roll, and, "Then, you may add two [hit] results." So you don't have to add those results, so cancel the roll, then you add nothing. Guaranteed miss. Failsafe. Do it again whenever needed.
Pair with an ionizing weapon and you could put one enemy out of the fight for a long period of time. Long enough to clean up his help, then come back for the kill.
There's probably a ton of better options out there, I just thought about it today and thought I would share. Thoughts?
