The Cursed Shield is the worst shield in the game; not only does it inflict numerous status ailments on the wearer, it makes the equipped character weak to certain elements. To obtain the shield, the player must recruit Locke in the World of Ruin and go to Narshe with Locke in the party, as he's the only one who can open the locked doors within the city. The shield is found inside the house right up the stairs to the right of the relic shop.
