I'm surprised Harry only has Fair investigations.
Is Conviction the equivalent of SotC's Resolve, or is Resolve also in DFRPG?
Also, typical SotC heroes start out with 5 boxes of stress. Harry has 4/4/3. Is there a formula reached for that, or is it just something innate to the DFRPG?
Conviction governs the amount of power you can throw around. Harry has a lot of this.
Discipline governs the amount of control you have over that power. Harry... is a little sloppy in this department. That's why he favors Thaumaturgy if he can do it: because it's slower and more deliberate, his lack of control doesn't bite him on the butt so much.
If I understand correctly, this is also why Harry is using focus items. It's granting +1 to Offensive Con(trol).
And why he prefers Thamutergy; +1 Control (Divination)?
