Having played a lot of FFG Star Wars, I've been thinking of how to build in a narrative result to FBL (and my hack). Essentially, every roll should have the opportunity of saying "success, and...", "success, but...", "failure, and..." or "failure, but..." as well as a straightforward "success" and "failure"
I've come up with something which I think could work well, but does add another layer atop the existing mechanics which I'm not sure works as elegantly as I'd like.
Essentially, an extra D12 is rolled during every skill check as a "Degree Die" (name is horrid, I know). This is used for determining advantage / disadvantage, but does not grant successes or cause trauma. It is also not rerolled when a roll is pushed.
On a roll of 10-12, an advantage is granted to the roll, with a 12 being a "triumph". On a roll of 1-3, a disadvantage is suffered, with a 1 being a "despair". Triumph means something really benefitial occurs (outside of success or failure) while despair means the opposite.
Example: a PC rolls and gets 2 successes in his regular dice pool, but the Degree Die comes up with a 2. The PC spends the 2 successes as normal, but there is some additional complication that occurs.
I'm thinking that maybe only the PCs get this extra die.
