I have a rules question: how does dojo of the flame cluster attacks (add a die to your class pool) work for mage (roll d4 to determine how many d6 are in your class pool). Is it d4+1 d6 or is it d5 d6 or something else?
Your first idea is the right one. The d4 sets the base amount of class dice each day, and cluster attacks adds more dice on top of that. 👍
