Here's what we've worked up so far.
https://drive.google.com/folderview?id=0BwouQYZcwYj2aDdORkgzeVNBa2s&usp=sharingWe're in the process of removing Discipline, Conviction, and Presence. Replacing them all with Will.
This means removing the Social stress track and just having Mental, as in Fate Core.
In theory (still being worked out):
1) Spellcasting powers will give you a Magic stress track, and the casting stress mechanic will work the same.
2) Spell Power and Control will both be based off of Will, but at start you can choose to take a +1 to Power and a -1 to Control (or vice versa) to establish a different feel for your caster.
3) Specialty, Foci, and Refinement bonuses treated as normal.
4) We're debating if Rote spells should be based on the average, rounded down, of your Power and Control instead of just Control.
