Follow up post: Here (lumpy in a good way)
Background
I saw this blog post (http://tarsostheorem.blogspot.com/2020/04/dice-are-statblocks.html) and liked it, and it made me think of the below … (for a brief moment it was as if G+ was alive again).
New method to generate standard D&D stats using one throw of the dice
Bored of the old ways? Got a sore wrist? Hate your DM … well we’ve got you covered!
Generate the standard six D&D stats using one throw of 3D6 (plus some rules).
Rule Set 1: Mimicking a traditional 6×3D6 method:
Roll 3D6, and quickly gather them into a ‘caterpillar’ shape:
TLDR: Add up the exposed faces; except the end cube where there is a subtraction.
Stat 1 = add up the front face (i.e. 1+6+4)=11
Stat 2 = add up the top face (i.e. 2+ 4+1)=7
Stat 3 = add up the rear face (i.e. 6+1+3)=10
Stat 4 = for the left-most cube (head of the caterpillar) add up all exposed faces; including the left-most face (i.e. 1+2+6+4)=13
Stat 5 = for the right-most cube (bottom of the caterpillar) as above, but this time subtract the right-most face (i.e. 4+1+3-2)=6
Stat 6 = for the central cube add up all exposed faces (i.e. 6+4+1)=11
PS – this is method is not suitable for 3D6 down the line, unless you randomise the order of ‘the line’ first.
The Stats
I did a ‘brute force’ Excel simulation, and I can’t be certain if the results are lumpy but the lumps are hiding in the averaged-out results, but anyway, this is what I got (for about 24,000 stats, about 4,000 PCs):
The green line is what you expect using a standard 6x3D6 system, and the blue line is my Excel simulation (fingers crossed I didn’t screw something up). So, the ‘3D6 caterpillar method’ using Rule Set 1 fits the standard 6×3D6 curve quite well. There are two weird artefacts at 7 and 14. I twiddled with the rules but this seems to be the best overall compromise for result vs rule simplicity. Also 7 and 14 in most games do not give a bonus or penalty.
But if you’re not a stickler for 3D6, then there is this for 4D6(drop the lowest):
Rule Set 2: Mimicking the traditional 6x4D6 and drop the lowest roll method:
Again, roll 3D6, quickly gather them into a ‘caterpillar’ shape:
TLDR: Add up the exposed faces; except the middle cube where it might be a 14
Stat 1 = add up the front face (i.e. as above) i.e. 11
Stat 2 = add up the top face (i.e. as above) i.e. 7
Stat 3 = add up the rear face (i.e. as above) i.e. 10
Stat 4 = for the left-most cube (caterpillar’s head) add all the exposed faces (i.e. as above) i.e. 13
Stat 5 = for the right-most cube (caterpillar’s bottom) add all the exposed faces (i.e. 4+1+3+2)=10
Stat 6 = for the centre cube add all the exposed faces (i.e. as above) – but if the front face is a 4, 5 or 6, add the bottom face (spoiler – this will always give a 14)
The Stats
Again, I did a ‘brute force’ Excel simulation, and this is what I got:
The red line is what you get with 6x4D6 (i.e. and with drop the lowest result) and the blue line is my Excel simulation (again fingers crossed I didn’t screw something up). The ‘3D6 caterpillar’ using the above rules follows this curve surprisingly well. There are not even substantial artefacts.
Rule Set 3: Simple method:
Roll 3D6, and quickly gather them into a ‘caterpillar’ shape:
TLDR: Add up the exposed faces; except the end cube where there is a subtraction.
Stat 1 = add up the front face (i.e. 1+6+4)=11
Stat 2 = add up the top face (i.e. 2+ 4+1)=7
Stat 3 = add up the rear face (i.e. 6+1+3)=10
Stat 4 = for the left-most cube (head of the caterpillar) add up all exposed faces; including the left-most face (i.e. 1+2+6+4)=13
Stat 5 = for the right-most cube (caterpillar’s bottom) add all the exposed faces (i.e. 4+1+3+2)=10
Stat 6 = for the central cube add up all exposed faces (i.e. 6+4+1)=11
The Stats
It would appear you’d get a PC with stats somewhat between 3D6 and 4D6 (drop the lowest).
How the 3 Rules sets stack up
Rule Set 3 – hydrid ‘simple’ method
Rule Set 2 – mimicking 4D6 (drop the lowest)
Green curve: 3D6, Red curve: 4D6 (drop the lowest); Blue curve: By Rule set
OK, well that’s it.
:O|

Me on DriveThru. At the moment I’m mainly pimping my procedural dungeon generator using Hex Flower game engines: In the Heart of the Delve & Dangerous. It’s PWYW and close to being ‘Silver Best Seller’ on DriveThru.
Is there a way to hide the letters on the Excel mapper?

Yes-ish, one way is to make them a tiny font size.
Trying to colour match could work too.
It’s been a while since I’ve thought about this … I’ll post again if I think of anything else …

Thanks, good idea on the colour of the font. I’ll try that later

I like this idea.
How do you achieve the randomness of the cube face positioning?
Would it be better having a tower, i.e. the numbers rolled are the “blind” (unused) ones?

Apart from the top number that is

Scratch that, the cube face positioning applies as well

The idea is to join the cubes up ‘quickly’ into a caterpillar before you have too much time to think about it. Of course, anyone inclined to ‘cheat’ would probably try to work the system …

Can you download instead?
It is shareable according to Google
BTW this is an Excel spreadsheet so you may not be able to open directly

Yes, thanks! There are half the combinations I thought there were!

That’s pretty damn cool. I may try this with a group some time.

What a funny, surprising idea! I like the “simple” method because it’s elegant. I think the others are too fiddly and take away from the charm of what this is and why you’d want to use it in the first place.
