So if the shooter wants to try and activate their autofire, they add one Purple die. But the quality says that they can activate autofire more than once (depending on how many advantage they roll). So if they want to try and activate it twice, does it go up two?
Or is it just "Mr GM, I want try for my autofire"
"Fine, here's your extra purple die"
*ROLLS*
"Sweet! It just came up with 4 advantage! I get 2 autofires!"
