I'm looking into unique stunts that affect dice rolls in gameplay. Are there any rules or precedent on the use of more than 4 Fudge dice in rolls, or using a die to determine outcomes?
I'm thinking of stunts like these examples:
Desperation: You may roll a 5th die during combat rolls as long as 3 or more stress boxes are filled.
Cruor Vitalis: Heal a target ally for d6 shifts, but they must roll Will of the heal value or suffer mental stress.
Are there actually any rules against using extra dice or using D6 in rolls, or is that up to the DM?
