Sap Guard (レデュースガード: Reduce Guard) is a debilitating spell featured in Valkyrie Profile, Valkyrie Profile 2: Silmeria and Valkyrie Profile: Covenant of the Plume. It can be learned by Sorcerers, but also Archers and two Light Warriors in Valkyrie Profile 2: Silmeria. In all its iterations, it reduces an enemy's RDM and RST (only RDM in Valkyrie Profile), and, as all debilitating spells, can only be cast from the battle menu.
