Final Fantasy 4 Cheats

Hidden room:
After you get Tellah to join your group for the first time, and after you have also already obtained the other two treasures from inside of the two treasure chests in that room where he was first located, you then can also grab something else while in that same room. While still in the water, after you have taken those two treasure chests on the way into that water, you can go behind the big waterfall that was right beside him, into a secret room. While in that secret room, you will find three treasure chests. For Final Fantasy 4 Easy Type, they seem to have the same exact treasures inside: a Cure 2, an Elixir, and 1000 Gold; for Final Fantasy 4 Hard Type, those three treasures from the three treasure chests are a Dry Ether, an X-Potion, and a Phoenix Down. There are apparently no monsters in this secret room.

How to beat Milon Z.:
Cast some Cure 4 spells on him or give him some elixirs to kill Milon Z. easily.

Easy experience:
When you get Edge, he is only at level 25. To level him up easily, go to the stairs at the Tower of Babil as soon as you find Edge, but do not enter. If you do, you will not be able to return and save. Walk around until you find a group consisting of a Sorcerer and two BladeMen. Quickly defeat the BladeMen, as they are capable of casting Bio. Do not touch the Sorcerer. He will call in a Green D. or a MadOgre. Kill off what he calls in, and he will call another one. Keep repeating the process and you should get an average of 6,000 experience and 2,000 gil for each fight. If you get hurt, return to the save point.
