Also, regarding (b), fortune can only change blank dice to successes, not all failures. Why the distinction? Well, who knows? Perhaps there are situations where a die result counts as a failure, but isn't blank...?
Right, good point. Will try and remember this!
There are several other rules clarifications I've found since re-reading the rule book after our first game, just have to try and remember them all to pass onto the group next week!
