I have not fudged any rolls for players, only some mechanics when the players act in a way not defined in the scenario.
When is a correct time to fudge a roll and how often should it be done? Does anyone have an example of when the GM fudged a roll for them or when they fudged a roll as the GM?
My GM sometimes lets player's close roles to be rolled again if we are on a bad luck streak. Funny thing lately the rerolls have been worse! It lightens the mood in the room and makes failing, dare I say, fun.
I know our GM has balanced out a few of our encounters. He has hinted that future mistakes will be more 'permanent.' By carefully telling the group about a few fudges he is preparing us accept the roll of dice good or bad.
