When I elect to "spend" a die (or dice) to power special abilities do I spend them before or after the roll? If I spend them before the roll, obviously I'd just roll fewer dice. If I spend them after the roll, what stops me from spending the least desirable result, or is that the intent? (Noting that sometimes there won't be any "bad" results for an easy pick.)

Thanks!

Spend after. You can pick to toss a lame dice. Look at the Star Destroyers preview for the example.

Yep spend after, so you can put those blank results, or surplus accuracy results to use

Bitchin'.

Thanks guys.
