@JeremyECrawford I asked this last week and am re-asking in case you missed it. Not trying to be pushy. If you take a feat with +1 ability score, but it's already 20 can you put that score somewhere else or is it lost?

If a feat gives you an increase to an ability score that you can't raise any higher, there is no increase. #DnD https://t.co/xqcw05wnuW
