Good question, and I will probably have more moments like this being a first time creator and forgetting to explain some features. The essence is for the starter sets, my goal is to lock all the classes except 2 and then as you play, you unlock new dice sets and the supporting dice for them using that essence, there are plans for dice and board skins that can be used with that essence too (also open for other suggestions, character skins too). I'm currently working on a Gun dice set along with the ACT IV soft launch in the next couple days. Appreciate you playing and asking questions!
