The Hexlock Shield is a shield that debuts in Fire Emblem Gaiden. A shield that is tempered with a bevy of potent arcane energies, it protects its holder against magic. The effect slightly differs from games.
In Gaiden, the shield reduces the accuracy of magic attacks inflicted on its holder to 10%, while in the remake, it halves the damage from Black Magic and raises the holder's Resistance by 7.
