Basically, the way it works is this:
- For each of the small circles, roll 4d6 and write the sum of THREE of them on the plastic over the circle. (I've used this system with 3d6 straight as well, and still got pretty decent characters.)
- Repeat until all the circles are filled.
- Rotate the plastic circle until you get a characteristic array you like matched with the characteristic name labels in the bottom quadrant of the array.
- Once you've chosen a set, you can rearrange them, but at a cost:
.....For the first pair, each score of the pair is reduced by -1.
.....For a second pair, each is reduced by -2.
.....For a third pair, each is reduced by -3.
And so on, if you really want to play around with them.
Note that I have included the Strength reduction I use for the teensier races. If you hate that idea, just ignore it.
