Sap Power (レデュースパワー: Reduce Power) 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 two Light Warriors and two Archers in Valkyrie Profile 2: Silmeria. In all its iterations, it reduces an enemy' attack power and, as all debilitating spells, can only be cast from the battle menu.
