Thanks for the response! Ok, I didn't realize my dice were different (but I were suprised to see I sometimes got numbers higher than 6 - this explains it). Well, perhaps when you hover the dice you just get a "one row x cols" table folding out showing all the sides (unless you plan to have 20 sided dice, in which case you may have to make it a 5x4 grid, for example)?
Another thought. I ended up just rolling all my dice first, then activating one rune at the time with full knowledge of what my different numbers were. Now that I understand there will ve drastically different dice types, one thought is: Would it be more nervous and exiting if you had to use each dice before rolling the next? And should each rune only be usable once per turn? Perhaps this will call for more risk taking but also be more rewarding and more nerve wrecking?
