Sorry if this has been discussed elsewhere.
I'm asking for opinions here regarding when to upgrade Difficulty Dice into Challenge Dice as opposed to simply adding a Setback dice to the pool. Please note that I have the Beginner Game but no access to the Beta version of the rules.
What circumstances feel right for upgrading to a Challenge as opposed to applying a Setback, and why? Should it only be when there's a chance of Despair setting in? I think that's the intention, but cannot confirm if it is. In all honesty, if there are any rules of thumb regarding this question, I either can't find them or there's simply not enough of them (or a cogent enough one to negate this confusion).
In the Beginner Game, firing into an Engaged combat bumps a Difficulty into a Challenge. However, firing while falling nets you two Setback Dice. Is it right to assume the bump to the Challenge in the first example is because a hero might injure his friend on a Despair?
Thanks in advance!
