I have a question regarding the d6 impact rule. Do I roll once and apply it to all who are impacted During the flip. So say I flipped and got 3 works with it and I rolled a d6 and got a 6 would I apply to all three or would I roll a d6 three times and apply them separate.

Edit: the only similar rule I could find was the hellcann FAQ question saying you would roll once and apply it to each hit or crit in the shot.

Just roll once per flip.
