You may use three methods to generate your ability scores:
· The standard method (4d6, drop the lowest, do six times, arrange as desired). If your best score isn’t at least 14 or your modifiers add up to less than +2, you may reroll the whole set.
· The organic method. Roll 4d6 and drop the lowest six times to generate the six ability scores in order. Then you may reroll any one score (you don't have to keep the reroll), then you may swap any two scores. If your best score isn’t at least 14 (before the reroll) or your modifiers add up to less than +2,1 you may reroll the whole set.
· Point buy as described in the DMG, page 169 (pages 19-20 if you have the 3.0 version). If you choose this method, you get 28 points to spend.
Create two sets of ability scores and use the one you prefer. You can, but do not have to, use the same method for both. (Hint – use a random method for the first, then you can fall back on point-buy if you really aren’t happy with the first set, guaranteeing that you won’t get stuck with awful scores.)
