I've been looking around in the FAQ, and asked around the subreddit, but couldn't get a satisfactory answer to my question:
If a character is using a weapon or gear that grants automatic advantage or success (ex.: Superior), do those inherent advantage/success get doubled by the Gambler's Double or Nothing ability?
I argue they would, as they are added to the check as soon as the dice are rolled, and can decide between the roll being successful or not, and the DoN talent triggers after the roll is resolved. That being said, I'm not a brilliant man, and would appreciate being set straight if I'm off-base.
