Art of Blades

Art of Blades is a technique book in Aretisia: Tenebris Dominus.

Description
When equipped, it removes a character's shield slot and replaces it with a second weapon slot. This allows them to equip two weapons at once, potentially doubling their damage at the cost of a shield. As melee characters are the only ones who can equip a shield, this book is useless to Energy based characters.
