From the game Final Fantasy II for the Super Nintendo
I'm sure most of you remember that if you use weapons, armor, or accessories made out of any metal or any silver in the Dark Elf's cave. However, there's a little glitch that can be exploited if you don't feel like using wooden gear or your bare hands to fight.
Simply put, make sure all metallic/silver equipment is unequipped before the start of any random battle. Then when you get into battle, equip your metal weaponry(and shields, if you want) and you won't be paralyzed for that battle! Just remember to unequip the items after the battle and before the next battle and you can dominate your way through the Dark Elf's cave!
