Class is gameplay component in Baten Kaitos: Eternal Wings and the Lost Ocean that determines certain abilities of characters in battle.
There are six Class levels; Kalas and Xelha both begin as Class 1, Gibari begins as Class 2, while Lyude, Savyna and Mizuti all begin as Class 3. A character's Class is raised (called a Class Up) by presenting a corresponding Class-Up Magnus to the Priest in the Church and Praying. Since a character's Class Up is tied to a specific Magnus, Class levels can be skipped.
