Final Fantasy VI
The Ragnarok is one of the most powerful swords in this game. It is obtained by going to the Weapon Shop in Narshe in the World of Ruin, and having Locke pick the lock to enter. The Weapon Shop owner is hiding in the back room, and shows the party a stone, which is actually the Ragnarok Esper. He offers to refine the Magicite and turn it into a sword, or leave it as the Magicite.

The sword has 255 Battle Power, and increases Vigor, Stamina, and Magic Power by 7. It also increases Speed by 3, Evade by 30%, and MBlock by 30%. Due to a bug in the game, the Evade bonus has no effect, and the MBlock bonus also affects physical attacks. The sword consumes 10 MP each turn to perform an automatic critical hit. It will randomly cast the Flare spell in addition to its attack. The sword can be used by Terra, Locke, Edgar, and Celes.
