Alright I've sunk a good 500+ hours in and have been playing as a Redguard and chose the The Warrior birthsign. After learning some stuff through trial and error I came to the realization that I would have been much better off picking a Breton with The Mage birthsign. Is there anyway I'd be able to hex edit my save file in order to change my class and birthsign? Starting over isn't really an option I'd want to go for.

Not without breaking the xbox's EULA...thus not for discussion here.
