Backstabber doesn't care about weapons, only whether or not he's in a printed arc. It doesn't matter if a turret has the potential to hit him - if he's out of the arc, he gets his bonus.Ok. I'm actually having trouble following that, and I am still not sure it answers the question of what to do about backstabber if he is in arc for one weapon and out of arc for another on the same ship.
But the previous ruling was defining a ship as "out of arc" for turreted weapons but "in arc" for non turreted weapons. Does this reply address that issue or not, I can't tell? Because if backstabber is in the falcons arc with concussion missiles but out of arc for the turret, how do you resolve Backstabbers ability?
