Hey guys. I was browsing the forum, and I came across a method for rolling stats that was presented as: 3d6B2. What does that mean? If I had to guess I'd say it was roll 3d6, lowest becomes 6. Thanks, and as always, go nuts.

I do believe that means "roll 3d6, drop the worst die, your result is what remains". The B stands for "best", as in "keep the best 2".

Makes sense, thanks :smallsmile:

I would assume it means 3d6, keep Best 2. Which would be the same as roll 3d6, discard lowest.

Treating the worst dice as 6 would probably be the same as 2d6+6 (with a possibly slightly higher average, not quite sure).

Yup it shifts the mean up:
2d6+6 (http://anydice.com/program/f22)

2d6K2+6 (http://anydice.com/program/3c45)

And significantly more than I would have expected.

Since we're already at it: Is there a roll that gets better results than 4d6 drop lowest, but not as good as 2d6+2, with still a maximum of 18?

the actual most common roll of 4d6b3 is 13, which is the same as 2d6+6. so, technically, no.

3d4+6 will give you similar chances of hitting 17-18 as 4d6 drop lowest, with a much higher floor to work from.

I've seen it represent rerolls. So 3d6b2 would mean roll 3d6 and reroll any result of 2 or less.

3d4+6 gives an average roll of 13.5 What i was pointing out is that Yora's comment gives no range whatsoever to work with.

Most common roll yes, but everything else is quite significantly different.

In 2d6+6, the minimum result is 8, in 4d6b3 the minimum is 3. The chances for an 18 are 2.78% and 1.62%. That's close to double for 2d6+6.

3d4+6 has a minimum of 9, but that comes with a lower chance for an 18. It does conform to my requirement of being "not as good as 2d6+6), but by that I actually meant the possibility of scores lower than 8.
Stupid math, always requiring exact definitions. :smallbiggrin:

4d6b3 still has a 30% chance of getting at least one (or more) scores of 7 (or less). I think that's still too high for my taste. That doesn't require particularly bad luck and is to be quite expected when creating a character.

in order to get anything between those chances of the highest rolls you need dice that dont exist.

It also depends on what you mean by "better", since there's various different properties of the different curves that some prefer for different reasons.

1d10+8 would give you a 10% chance at an 18, and 9 would be your lowest possible state.

You could just do something really weird, like 1d8+1d6+4. Gives a range from 6-18, with a 1/48 chance of 6 or 18.
