"Organic" creation is one of the methods in the DMG. Essentially, roll 4d6 drop lowest in order, re-roll one of the scores, swap two scores. The method results in very interesting characters.
Ah, I do 4d6, drop the lowest, arrange in any order.
And I allow you to reroll “4-F” set of stats (fail the draft physical) if you want - that’s if there’s any stat lower than 7.
