For Armies of Primus I needed some custom dice for attacking and defending. When I was starting out I simply used standard d6’s from the dollar store and provided players with a roll chart. Using a roll chart was useful when fixing the die face balancing before I committed to a final layout and design. After I was sure of the balance, I printed black and white symbols onto mailing labels and cut them by hand. As an added protection I spray lacquered the stickers with some Rustoleum NeverWet spray. It was a bit of work but in the end, the beta dice work great and are much easier to use than a roll chart.
