The Seven Hero Codices are grand magic books that bestow magic to the world. The Four Elemental Codices and the Three Phenomena Codices come together to make seven volumes, and they are stored within the Hall of the Seven Heroes at the Library.

The Codex that brings water magic to the world. The boss, Water Spirit of Light Rain, attacks with water orbs and tree-like arms.

The Codex that brings wind magic to the world. The boss, Eerie Bird of Headwinds, has powerful rush attacks that take advantage of its large frame, and wings that stir up Wind magic.

The Codex that brings earth magic to the world. The boss, Colossus of Catastrophe, attacks in a wide range with giant arms and shockwaves.

The Codex that brings fire magic to the world. The boss, Incarnation of Raging Flame, not only uses fierce melee attacks, but also mixes in flamethrowers and explosions, so be very careful.
