I'm probably doing something stupid, but I honestly can't figure this out. I just created a level 7 Half-Orc Paladin with stats below. When I try to assign level 1 spells it says Spell Action Failed: Ability Score Too Low, but I don't know how that is possible with my CHA at 14. Any help would be appreciated. Thanks.
