I know the all d6 route has been discussed before on these forums but has anyone made alternate combat tables and saving throw tables using only d6? I have started to hash it out but it is proving to be very difficult. What i thought of doing is combining the alternate to hit tables with the 2d6 variant of the chainmail tables.

Yes, I've given it a go or several and as I recall so has Trent Foster.
Chance of rolling number or greater on 2d6:
2: 100%
3: 97.22%
4: 91.67%
5: 83.33%
6: 72.22%
7: 58.33%
8: 41.67%
9: 27.78%
10: 16.67%
11: 8.33%
12: 2.78%
Chance of rolling number or greater on 3d6:
3: 100%
4: 99.54%
5: 98.15%
6: 95.37%
7: 90.74%
8: 83.8%
9: 74.07%
10: 62.5%
11: 50%
12: 37.5%
13: 25.93%
14: 16.2%
15: 9.26%
16: 4.63%
17: 1.85%
18: 0.46%

My "Alternate alternate combat system" is based on 2d6. I see that the S&S combat system is also 2d6 based  |

What I did back in the 1970's if I only had d6's (when we first played D&D, my friend had the only set of rules and dice between us) was simply to roll 2d6 to equal to or below AC to score a hit.
This, I believe, effectively inverts dwayanu's probablity charts and means about an 85% chance to hit an unarmored (AC=9) person and about a 3% chance to hit someone in platemail with shield (AC=2).
What it does is allows a DM to keep the basics of the rules the same, even if the actual odds have shifted, and it's easy to work with. The disadvantage, as with all curve probabilities, is that it tends to not work well on the extremes becasue a +1 is no longer the same across the board. But it is simple! :-)

Epées & Sorcellerie is enterely 2d6-based, including abilities scores. So AC = DEX or by armor worn, and characters /monsters get a bonus for level.
I should check S&S, but I guess it allmost compatible in most ways (I only possess the first version). It's very close from Traveller (& from Barbarians of Lemuria as far as I can see).
A crossbreed of all these would probably give the 2d6 games we need - a lot of people tinker on this idea.

I really like your idea Fin! Never thought about it but it would work for sure. I might give both routes a try...

With the "AC or less on 2d6" method, one could keep fights from dragging on too long by making a natural 2 or 3 (1 in 12) an automatic hit.
Thus, adding a shield to plate means nothing -- until you bring in bonuses and penalties. A +1 on attack means that plate alone is hit on 4 or less (1 in 6), but a shield means a 2 or 3 is still needed.

Just for the taste of tinkering - the HouseRuleJunky syndrom strikes again:
+1 modifier : roll 3d6, keep 2 lowest.
-1 modifier : roll 3d6, keep 2 highest.
The strong fighter becomes suddenly very strong. Note that, once again you can roll 2d6 under Armor class, with a dex modifier on the same way, for sneaking & tumbling. Sword&Sorcery feeling!
For saves, something like roll 2d6 under 5+half level, round down should work.

I'm thinking now looking at the odds and doing some test charts and things that 3d6 would do the job nicely. I will post my alternate charts when i am done..

Just curious about your choice of 3d6. 1. 2d6 works better in the "equal or below AC to hit" model. If you migrate to 3d6 you need to redefine AC. 2. 3d6 (3-18; bell) gives a number range similar to d20 (1-20; linear) but the probablilites are way off. Is this a potential point of confusion for a person familar with the d20 model? Not saying it's a bad idea, just trying to understand your plan is all.  |

Well what i was suggesting was rewriting the alternate combat chart in men and magic to fit the probability of 3d6 or 2d6 (not sure which one yet.) as opposed to just rolling 2d6 under AC. I do like that idea though it just seems like it could get complicated but i am planning to try both out and see which one would work better.

I like the idea of AC = dex for its simplicity.
The only concern (if you would call it that) I see is that it may over-emphasise the importance of ability scores. Each point of dex means one extra chance of avoiding a hit. That is a significant advantage -- and when it comes to PC survival, what player doesn't want a significant advantage?
I guess this effect might be offset in other ways, but still... a feature of OD&D is the modest number, and size, of bonuses.
Something to ponder, perhaps?
