That means if you are cloaked and start charging you will uncloak whether you've fired or not. The Infiltrator's Tactical Cloak power registers a shot fired when you start charging the Graal, rather than when you actually fire off a shot.It takes time to get used to this if you have been using the classic shotguns. It makes shooting moving targets a bit tricky, but this can be remedied by leading your shots. Because the Graal shoots slower, but heavier flechettes, there is a noticeable delay from shooting to impacting your target.The Graal only expends one shot, regardless if it was charged or not.
A safer way to use charged shots is from standing cover behind walls/pillars you can simply run behind and pop out from.
