Final Fantasy III Hints & Cheats

Back in the original Famicom FFIII, Onion Swordsman was the first job you start as (unlike Freelance from the DS version), but you can play this job in the Nintendo DS version as well by unlocking it. Onion Swordsman is one of the most powerful jobs with the Onion Equipment + past level 90's.

How to obtain:
1)Register someone elses's (or multiple) communication ID under Mog Net.
2)Send message to another PC 7 times
3)Send and receive 4 messages from Topapa, on the fourth one you will receive a message to do a mini-quest.
4)Go to Ur (First town in the game)
5)Talk to Topapa
6)Go to the cave up north of the cave
7)At the drop hole, you will have an event and then will be proceeded to fight 3 bombs
8)After the battle, you will obtain a piece of crystal, which will unlock Onion Swordsman

In the Nintendo DS version of FFIII, there is a secret dungeon that contains a secret boss harder than the last boss, in order to obtain access:

1)Send a total 7 mails to another PC (one or multiple) using Mog Net.
2)Send 4 mails using Mog Net to the NPC: The 4 Elderly
3)Send 4 mails to King Arusu and after reading the fourth one, you'll unlock a quest
4)Go ride on the airship that can go underwater
5)Head for the floating island and once finding it, go exactly east..
6)You will eventually see a shadow in the waters, once you do go underwater to enter the cave
7)Soon after entering the dungeon, you will meet the secret boss

*This boss is notorious and mean. It does a total of 4 attacks per sound and also uses Meteo. Please be at a very high level before attempting this fight.

*WARNING: This item duplication will ruin the game play, please note to do this at your own risk. If may also damage your save file so please duplicate your save before you attempt this.

In Final Fantasy III, all useable items (not weapons/armors/magic) can be duped using this method, as mentioned, please use at your own risk.

Procedures:
1)Open menu screen via non-battle.
2)Select "Items"
3)Put the item you want to duplicate in the very top left corner in your item list
4)Enter a battle randomly
5)When in battle, go select "Item" on any characters.
6)Your cursor should be at the very top left of the item box, the item you have placed there. Once you're here, hit UP and A button at the same time
7)This will briefly take you to Wepon/Shield list (about 1/2 second). If you see this, the code has worked after you hit "cancel' or B button. Go to your invetory and you will notice that the item quantity has been added by one.

With this method you are able to duplicate any demishable items, even items you can't by such as Chocobo's Rage, Elixir, Phoenix Down. Note: This doesn't work in the PAL version of the game.

YOU MUST HAVE THE NAUTILUS FIRST. SAVE BEFORE DOING THIS.

If you take the nautilus and head to the western side of Saronia (the continent with the castle on it, upper left corner of map, not on the floating continent), there's an area with the most trees on that side. There should be a place between two rivers. If you touch down on the tip of this area that touches the ocean, you can actually dive into it. From there, you can 'bore' into the continent. If you exit into the ocean, it will push you out and you have to dive into the continent again. When tunneling through the continent, you won't encounter any creatures, as far as I can tell.

It is possible to surface at any point within the continent. In fact, you can surface through mountains. Like diving into the continent, entering an area you can normally fly around in will shove you out of the other area and not let you back. With enough skill and dumb luck, you can actually get to Falgabard without the Invincible. Of course, you can't leave after that, but hey, it's still funny.

When you first get the Mini spell from Desch, continue exploring until you find a forest with a gnome and a healing spring. He will tell you how to reach Tozus. If you have not taught yourself Mini, he will not give you anything. If you taught yourself Mini, he will supply you with another Mini spell. You can do the same with the Toad spell that you recieve from one of the blind men in Gulgan Gulch. You can do this trick up to four times if you wish, scoring one Mini/Toad spell per party member and one for your inventory.

This glitch works as if the game (which only counts whats in the inventory in this instance) thinks that you have originally sold/trashed the original Mini/Toad spell that you were supplied with.
