Here is the prototype die I'm ordering for the game. The symbol is based on the dharma wheel which represents the 8-fold path in Buddhism.

I'm contemplating modifying it into a unique design which would represent the game itself.

Coming up with a design for the die was trickier then what I expected. From a production point of view. I can put ANY design on the die. But for me I believe that the symbol needs to be clearly identifiable from the POV of the roller.
