Polyhedral

Polyhedral provides dice to play RPGs. The Z6 is a special die type and can be used for RPG resolution in a novel way. It has a side for each of the platonic solids and one side that is wild. The wild side represents the die type of whatever skill your character is using. The procedure for making a skill check is: (1) roll a Z6 (2) roll the die type for your skill when the wild side comes up, otherwise roll the die type on the Z6. The result is the value of your check.
