In some games, there exists an MP-variant of the weapon that acts similarly to the spell Osmose, though it appears much more rarely compared to blood equipment. When a piece of blood equipment exists as armor it is most often as the Ensanguined Shield, which usually has excellent defenses but penalizes the user's stats in other ways. Blood equipment has appeared since Final Fantasy II, with the appearance of the most common piece of blood equipment, the Blood Sword. The Blood Lance appears the most alongside the Blood Sword.
