Shield Bug

The Shield Bug is a bug in Final Fantasy VI, which involves the Force Shield and the Cursed Shield. Normally, when equipped, these shields either grants statuses (Shell in Force Shield's case) or inflicts statuses (Cursed Shield's case). However, when equipped in the middle of battle, instead of applying the statuses that the shields are supposed to, they instead provide immunity to the statuses. For example, if Force Shield were to be equipped in the middle of a fight, instead of the user getting the Shell status, they would be immune to it. The only status that Cursed Shield does not grant immunity to in this way is the Condemned status, while protecting from Sap, Confusion, Silence, and Sleep, making this the only way to make Cursed Shield beneficial to the user.
