Fire Emblem: The Binding Blade

The Flux (Japanese: ミィル Mir) tome is a relatively common dark spell in the Fire Emblem series. It consists on invoking dark energy, which then engulfs the enemy. In the games where it has appeared, it is the most basic spell for users of dark magic, such as shamans and dark mages.

The flux tome is available in The Binding Blade, Blazing Sword, The Sacred Stones, Awakening, and Heroes.
