I'm sure I must have seen thirty sided dice advertised in Dragon; my high school DM had a whole shelf of the magazine and I read them religiously, even borrowing some to read at home.
I even managed to pick up a d34 somewhere, but I never physically saw a d30 until this week.
I'd completely forgotten about them until I read a post on Dungeon and Digressions that gave a 1-30 chart and mentioned the Order of the d30. I knew vaguely that The Armory was one of the only companies besides Gamescience that made precision dice and that they'd gone out of business (or at least stopped making dice).
Anyway, surprise, surprise, you can still get precision d30s. I just bought 2 on Amazon. I'm happy with the quality.
Now the question is, how do I use them. What I mean is, I can make charts for myself all day long but I really enjoy sharing with others. But I don't know how common d30s are among people out in the world. Should I incorporate a d30 in Grim's Roll All the Dice method, for example? Should I start making d30 charts?
Do you have a d30? Would you use a chart that required one?
