I can't find the rule now but somewhere I thought I saw that five was the most you could add into a PC or NPC's side of the pool (not including Boost Dice). I have a very difficult challenge coming up where the heroes have to save a city from being crushed by a droid left over from the Infinite Empire. The solution is actually role play/socially based but they of course will try to smash it first.
That said, it has a Brawn of 6 and a Brawl of 4. That would call for four Challenge Dice and two Ability Dice? Is that correct? Or does the pool cap at five dice?
Sorry about the nebulous question, I can't find where I read five was a cap before. Thanks for clearing things up for me!
