Crystarium system

The Crystarium System is the ability and statistics system for Final Fantasy XIII. Each character has a unique Crystarium System grid similar to the Sphere Grid of Final Fantasy X, although systems do not intersect. The System is fueled by Crystarium Points, or CP, which are won after every battle, and are spent to unlock nodes on the Crystarium Grid. Each character's Crystarium System is based around their Eidolon crystal and branch out in seperate planes defined by paradigms.

Roles
Paradigms model the Job System of games past while adding some level of customization and restrction. Each character in the field can take on one of six roles in the Paradgma; any combination of three characters' roles constitutes a paradigm. Paradigms can be changed during battle with a Paradigm Shift; however, what is more important to the Crystarium System is the particular roles that each character can take on. The six roles are as follows:

Each character has three major roles and three minor roles in the Paradigma System, and these classifications affect the amount of CP needed to unlock nodes in the Crystarium System.
