Well, I didn't think there'd be much interest to be honest. But apparently there is, so I won't send it the way of other mayflies.

erosomniac and his roommate were eventually successful in executing above plans.

I have a question regarding dice (though not the acquisition thereof) and average results for a given combination of standard gaming die. Basically I'm looking for a source that lists the hierarchy for average rolls.

Up til now, what I've been doing is just applying two rules: one, highest max roll = better, and two, more dice = better.

This gives me a hierarchy like this:

1d4 < 1d6 < 1d8 < 2d4 < 1d10 < 1d12 < 2d6 < 3d4 < 2d8 < 4d4 < 3d6 < 1d20

And so forth.

While this makes sense to me, I haven't been able to find a source that confirms or disproves it. And so I turn to Hatrack. Anyone know of one?
