Schema

Style is a term from Lightning Returns: Final Fantasy XIII related to game's innovative approach of the Active Time Battle system.

Composition
Each Style is composed of a weapon, shield, outfit, several accessories, and four abilities: it is up to the player to adjust Styles to fill his needs.

Naming Pattern
It is currently unknown how the naming pattern works, but possibly takes all parts of each Style that player assigned to it and determines the best name based on the preset names.

Usage
Styles can be changed in the middle of a fight similarly to how Paradigm system works in Final Fantasy XIII and Final Fantasy XIII-2. Shifting through different Styles is very important in battle as it allows to maximize Lightning's performance and gain additional time before the world will end.

Trivia

 * Some of the Styles share their names with Paradigms from the previous installments, e.g.: Cerberus.
