In Dresden Files, you can use magic to grant yourself a temporary skill; with 5 shifts of power, you could give yourself a skill of 5 in Athletics for a short while. (Or a longer while, if you use Thaumaturgy instead of Evocation.) But what if your Athletics skill is higher than your ability to cast magic? Aside from using a Maneuver (free tag for +2, additional uses take Fate chips once per roll), how can you improve a skill for an extended time when your skill is higher than your ability to use magic?
(For context, my character has 3 Discipline, 3 Conviction, and 4 Lore in a game with a 5 skill cap. I'm barely able to cast Evocation Maneuvers, and several of my skills are higher than my ability to cast.)
