You can only change after the pantheon finishes and is reset.
I'll try not to start another post on this but. How long does it take for a typical patheon to finish? 8 rounds = 8 days maybe?...
I'm also "light" side right now ...I enjoy it I like oak. I can see it getting old because I also like the Vampire Lord/ UB.
Hopefully this isn't going to become a problem.
