So today at work I had this very heavy set guy ask me if I knew where he could find polyhedrals. I was like "Huh?" He then said "multi-sided die." As if it was too complicated to just fucking say that in the first place. So I told him I'm still unfamiliar with the area. He told me he didn't mean in the store. I kinda glared and said "I wouldn't know in this city. I'm from out of state." At that moment I felt like going "Oh, sir, give me a moment. I want to Magic Missle this goblin to death and search his body for a polyhedral for you. And if he doesn't have it, well then by golly I'll just Magic Missle every last goblin in sight until I find you some polyhedrals."
We've come to the conclusion that a marble could not qualifty as a die as it is not a polyhedral. The smallest possible die is a 2 sided die (essentially a coin) followed by a 3 sided die.
There's something - does the term "polyhedral" refer exclusively to "multi-sided die"? If it doesn't, then it's stupid to use it and expect people to know it refers exclusively to "multi-sided die".
