I'm a noob so sorry if this has been addressed before. I know the FAQ says that when an effect allows you to add a die to the attack pool it can be a die that is not appropriate for the range of the attack. I'm assuming this is because some upgrade cards direct you which color die to add.
What about during concentrate fire. Can I add any color die I want? Am I allowed to add a black die to an attack being made by a class II VSD or does the added die have to be one the ship has the potential to roll?
Thanks and again I apologize if this has been discussed previously elsewhere.
