In Open Legend, Extraordinary Focus is a feat that
heightens your power and for the purposes of determining your attribute dice for action rolls, you treat the chosen attribute as if it was one greater
Having an attribute score of 9 is the maximum you can attain, so how can it be upgraded by one?
What happens when your attribute score is already 9? does it go to from 3d10 to 4d6, following the pattern? Or does it do nothing?
