I wish they had a better picture of the D5.

Having a little trouble visualizing that.

I have one of those D34s. I have no idea when or where I acquired it; I suspect it was accidental (i.e., used to be someone else's and ended up in my dice bag).

The expression for combining two dice is pretty simple, isn't it?

Let's say that d_2 is the value that the d2 gives you (in {1,2}). Then to get d_6:

(d_2 - 1)*3 + d_3

or, in general,

(d_i - 1)*j + d_j

It's just a very slight generalization of what you do to use two d10s to give you a d100.

I think the further generalization to n dice should be straightforward. If I had a couple of minutes, I'd work it out now.

Nah, I see it. Was just being obtuse. And thinking about hot sword-forging chicks. :P

I just saw that post. I can understand.

Feel like posting a link to her profile? This I gotta see. :)
