Players in the Invisible Fortress campaign get 33 points to use with point buy when creating their characters. They may also purchase ability scores above 15; ability scores of 16 and 17 each cost 3 points, 18 and 19 each cost 4 points, and 20 costs 5 points.
Below are all of the ability score arrays this rule makes possible, if you do not wish to calculate it yourself. Note that all of these arrays are before racial bonuses.
