important question: should I use the symbols as they appear on the TPB cover:

or invent my own symbols based on my interpretation of the text?
I may go ahead and do this on my own and just try to sell/eBay the extra sets.
I also can't remember if the two dice are the same or different - I believe they are unique. Which is sucky, cause that means a minimum order 10 pairs of dice, rather than 5 pairs of identical dice.
