Final Fantasy XIII Xbox 360 The character development is very like the Sphere Board of FFX. It has every character on certain professions (In the course of the story, every character also gets any profession) which can be separated from each other with skillen KP. It is advisable for each character set a major occupation. At the beginning you can still cross skillen bed, but this is no longer advisable after Sun. This system is both simple and ingenious. It works, and you have to break any teeth from the crown to understand it.
