Use the Cheatengine table (read thread for more info) while playing, and lock the characters' sphere levels.
Thanks for the reply.
I actually managed to kinda got what i wanted trough editing the savegame. It gives my character 255 character level, but i'd have to fill each time it empties.
I'll take a look at your method.
I dabbed with cheatengine in the past, so i should be able to give this a try.
