(Spoilers for Act 1)

I’m planning to take on Auntie Ethel early to get her to trade her hair for the +1 stat boost, but I got to thinking, do I need to save using it until my stat is already at 20? I know this can boost it over 20, and ideally the level system would recognize it and account for it, but I don’t want to risk it and get boned when I go to stat increase at level 8.
