Few corrections to Jynxy's post. The hidden effect is always 3x damage (never 2x). The hidden effect DOES stack with the 2x damage effect from AF3 however (on rapid shot procs) resulting in a 6x damage shot or barrage. This is rare of course, but 5k crit on a regular shot is very cool. Regarding barrage, the 3x-6x damage proc is only based on the first shot of barrage. If the first shot does proc 3x-6x damage then ALL of the other shots will as well. If the first shot does not proc, none of the other shots will either.
