So I was glancing over the basic character sheet, and noticed that only three skills use Willpower as their Characteristic. Three.
And, trying to think of any talents that directly improve Discipline checks (providing Boost die/removing setback, letting you turn Triumph's into successes, etc), the closest I can think of off the top of my head, is the one that reduces the difficulty of any Fear checks you make.
Now granted, I haven't done a deed dive on the books, which are at home right now to see if there is one, but I can't think of any specializations that provided benefits along this line?
Are there any that I'm just missing? Stuff like "spend some strain to upgrade a Discipline check/downgrade opposing Disc check" or "remove 1 setback for each rank from and Disc checks" etc etc. You know, the usual kinds of talents, but for Discipline.
