How does outmaneuver work when you choose to fire at a second target in the tie/sf's rear arc. Assume that the second target in rear arc does not have the tie/SF in its arc.

Thanks

Outmaneuver doesn't mention primary arc, so any firing arc would work.

Very few "in arc" effects specify a kind of arc, unless it calls out "Primary" "Auxiliary" "Special" or "Mobile" firing arc, it works in all of them.

@VanorDM and @Vineheart01 (and @Parravon in the other thread) are correct. Also, since you mentioned a second target, Outmaneuver is not limited to once per round, it will trigger on each attack (that's in arc and you're out of their arc).
