Assuming you use Chainmail for combat, the only problem left with all-d6 D&D is the Saving Throw table. Everything else can be done with 1 or 2 d6; except Saving Throws. Some have suggested 3d6 for them, but it's still a bell curve and that doesn't work well with the flat linear progression of the d20. So, how do we resolve this? Simple; we steal from someone else. Traveller has as one of its routine mechanics a 2d6 roll using two different colored dice thrown in succession. Thus, one is read as the 'tens' digit and the other as the 'ones' digit, just like percent dice. This gives us a linear spread of 36 possible results, from 11 to 66. This doesn't give exact percentages, like percent dice do, but they're close enough. The numbers on the Saving Throw table run from 3 to 16. We need to roll this number or higher, so this gives us percents in a range of 90% to 25%. All we need do (and I have done) is find the number on our 'd6%' table that corresponds most closely with the actual percentage required, as shown below:

This feels like the point where the experiment breaks down, to me at least. Everything else pretty much works. Come up with a new saving throw mechanic that uses 2d6 and don't try and exactly mimic the d20 chart.
I definitely applaud the out of box thinking, but I, personally, look at the chart and have no idea what is good or bad, etc.

Of course I think it's great! As always, I'm a 2d6 kind of player. I'd never really thought of approaching it with the 11 to 66 Spread. Ingenious!
It looks good enough to give it a try. However, I'm busy right now with a Homebrewed "Call of Cthulhu" WWII Adventure with my son at the moment (Fighting NAZI Zombies, Tentacled Nasties from beneath a old German Keep and trying to keep from going insane on a sanity check) but will give it a go when we head back to the fantasy realm.
You know, we ought to combine all of these 2d6 discussions into one cohesive document at some point. We'd basically have a proto-D&D/Chainmail rule-set that would look pretty sharp...

Oustanding work! Have an Exalt.

I'll see what I can do about that Wothbora. I've collected all this stuff together already and was working on a document for the next game I run. (whenever I find players for it that is)

I made a similar chart (I don't beleve the numbers matched those exactly, but I was creating it by hand so I probably made some errors) that was minimally serviceable, but which I eventually decided I didn't like because it didn't have enough granularity -- it glossed over too many of the little flavorful differences (like clerics having the best save chance against Death Ray or Poison at 1st level). My prefered method nowadays for recreating the D&D saving throw chart using 2d6 is the "percentiles on 2d6" chart that (from what I understand) was originally printed in Fight in the Skies and was reprinted in the article "What To Do When the Dog Eats Your Dice" in The Dragon. It involves 2 chart look-ups instead of 1 so it's clunky and slow, but it uses only d6s and maintains the granularity of the original charts. |
