Automatic Defeat of Enemies

If you have the Gem Box relic and you know the Vanish and Doom or X-Zone spells, then you can take any enemy out with one hit. Cast Vanish on the enemy, then cast Doom or X-Zone. X-Zone works more often than Doom does, however.

Relm's Sketch Glitch

This is a glitch in FF3. It can do many good and bad things to your game. It can: Give you LOTS of each item/weapon/armor/relic (such as 255 Economizers and several Gem boxes). Completely and permanently destroy the save slot you're using for the current game. Do a complete memory reset, leaving you with three blank save slots. This bug has its risks. There are a few ways that it can be triggered. The first is to go to the Veldt with Gau and Relm in your party. Use Gau's jump move, and when he comes back to your party quickly have Relm sketch him. The second method is to have Relm sketch a vanished monster. The Gau method is probably the best, though.

Unlimited Experience Eggs

To get unlimited Experience Eggs, bet Elixirs at the Colloseum for Rename Cards, then bet those for your Experience Eggs.
