The Agony of the Feat When you gain a level where you have the option to take an ability score improvement, you can instead select a feat. Alternatively, you can take an increase of one to a single ability score and gain a “half-feat”, allowing you to still improve your ability scores incrementally while also working toward acquiring a feat, including those feats which provide improvement to ability scores. As normal, no ability can be improved beyond 20 through non-magical means. Added to House Rules in 2023.
