Final Fantasy III Cheats

Easy Job Leveling
If you want to be able to level up a character to job level 99 in any given job in only a few hours, try the following. Enter a random battle with as weak of an enemy as you can find (since it's arbitrary how strong the creature is). Select the "Guard" command for your characters. Do this for four rounds. On the fifth round, kill the enemy party. Each character will receive a job level. Repeat as needed.
