I'm glad this is not a face-to-face conversation, or I'd have to point out that this is all wrong. A d30 averages a 15.5 result. A d20+d10 averages a 16. And none of the 'suggestions' work.

Don't stress over it. Lots of folks get probabilites messed up. Heck, I've posted some stuff in a hurry myself, then later did the "head-slap" thing and wondered what I was thinking when I posted it.

In general, any time you add dice together you get an uneven probability curve.

Here is my solution to the dice issue.

Use a permanent marker to 'connect the dots' on standard issue casino D6 dice. You can create 3 types of dice:

D3: for standard D3 rolls

D0-2: for D24, D26, and D28

D0-1: for D14, D16 and D18. You can also use the D0-1 as a modifier die with the 1 indicating +1 or -1 as required for D5, D7 or D9.

This was a nice idea for getting a d3... but the suggestions at the bottom are absolutely wrong.
How can you think of rolling a d24 by rollin a d0-2 ALONGSIDE a d4? :shock:
That would only create 01, 02, 03, 04 , 11, 12, 13, 14, 21, 22, 23, 24.
The correct use for a D0-2 (or any other d0-X) is as a control die.
For a d24 you can roll
(12 * d0-1) +d12
or
(8 * d0-2) +d8

This works exactly as the D%, which is
(10* d0-9) + d0-9

He obviously meant a d12 renumbered: 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 2, 2 rolled along with a d20 that was dual numbered: 1, 2, 3, 4, 5/1, 6/2, 7/3, 8/4, 9/1, 10/2, 11/3, 12/4, 13/1, 14/2, 15/3, 16/4, 17/1, 18/2, 19/3, 20/4. (That was annoying to type. :))

Or he wanted to roll it with a d10 to make a d30.


What I want to know is why the d3 uses angled lines over the 5-pip face but backward E over the 6-pip face. Would backward E look more consistent on both dice? Likewise draw the 1 diagonally on the 1-pip face so it looks the same as the 1 drawn on the 3-pip faces. (And is consistent with the 0-1 die.)

..or if you really don't want a d6 numbered 123123
(i just bought one for like 1€..) you can just fill with white paint the extra dots to make the 6 a 3, the 4 a 1, and the 5 a 2... It doesn't look extra-cool but you can clearly see the result you got.

Switch the 2 and 5 on the D0-1. I do not like those naked pips.

I have considered using a d4, d6, and d8 to simulate the d3, d5, and d7, and if you get the high number (I.e. 4, 6, or 8) then just use the average result instead of re-rolling. It would skew the result slightly to the average but wouldn't change the average.

why would you do that? :|
It's like having a d5 numbered 1,2,3,3,4,5.... It messes things up!

Just an easy way to simulate the funky dice without rerolls. It doesn't change the average and skews to the average a little bit.

It skews it by 25%, 16.6%, and 12.5%. That's a lot!

Don't worry we weren't criticizing the idea :wink: we were pointing out that it's not really a "slight" change... :D

You guys just hate me. :)

Seriously, the d3 and d5 are easy enough to simulate with d6s and d10, but using the d8 to simulate a d7 (with an 8 = 4) wouldn't be that big of a deal. Instead of 14% prob for each number you would have 12.5% for most and 25% for a 4. For a MDoA to succeed the prod would change from 71% to 75%. But I guess we have each had our say so I won't keep beating a dead horse.

I just wanted to say that suggestions in this thread will come really handy when playing with the Beta rules, I especially like the simple conversion of normal casino d6 to d2 and d3.

1. You're right that it probably wouldn't be a big deal.
2. Why mess with the probabilities at all? Just roll the d8 and re-roll all 8's that come up.

I imagine rerolls could be annoying.

i don't see them happening too often, since they
1) don't have huge chances (1/6 to say with d5)
2) the dice you're simulating are not widely used: you might have to roll a d5 not more than 3-4 times a session, and that's if the warrior is level 3 and uses it for MDoA

I mean, i hated to roll a d14 or d16 with a d20 rerolling 1/3 or 1/4 of the times! (wasting 19s and 20s!!) but with d7 i wouldnt mind rolling a d8.

How about trying it first and then you would know for sure if it is annoying or not.

Well I have done rerolling before. In AD&D I would roll a d8 instead of 2d4 (I have always disliked the standard d4) and rerolled ones (yes I know the distribution is totally different but his was when I was young and didn't understand these things yet). The rerolling was annoying but less annoying than d4s. :)

My 3rd level warriors and dwarves are going to be rolling a d5 more than 3-4 time a session.

I will probably just get the actual dice. I picked up a d30 this weekend from a local game store.
