Final Fantasy III

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.

First, you get all of your characters around level 60-65. You must have a Devout, a Summoner, a Black Belt, and a Ninja in your party. Put your mages in the back row, and make sure that the devout has every white Magic spell in his/her spell book. Then make sure that your summoner has every summon magic available for use.

The Cloud of Darkness attacks four times each round. It swipes its hand at your, uses bad breath, casts the spells haste and protect on itself, and uses lightning. After you deplete a portion of it's health, it starts using Particle Beam a lot.

The party should have the best armor and weapons equipped, and you want good defense and magical defense. Everyone should have their share of either ribbons, aegis shields, or onion armor so the bad breath attack won't affect them.

Use Arise when ever needed, and when not needed, use Curaja and Curaga every turn. When you use Arise, have everyone else that is standing use an elixir so they won't die. Intend to use up all of your shuriken and elixirs. I killed The Cloud of darkness in about 8 rounds using this technique, and this party at Level 66:

Arc: Summoner
Luneth: Black Belt
Refia: Devout
Ingus: Ninja

The four best jobs you should have when you first get to use the jobs is a Warrior, Black Mage, White mage, and Red Mage. These four jobs should help you a lot.

When you are able to get the job(s) monk and or Blackbelt get them on one of you characters immediately!

Monk and Blackbelt do massive amounts of damage even without weapons. Monks are the early stage but have about the highest vitality early and can do 9,999 as early as lvl 30 in some cases or earlier.

Blackbelts are the upgraded rank of monk but can do much more damage. Monks can boost their attack so on the next turn it can unleash a massive blow. Blackbelt also have super high vitality and agility so they can strike first, strike long, and strike hard.

In order to acquire the Ninja class -- considered to be the strongest class of them all -- you need to go to Eureka (a sidequest area found in the first floor of Sylx Tower) and go all the way through it. When seeing the last teleport (the one who usually takes you to an area with stores), turn all the way left and you will see a floating staff. By touching it you'll fight Scylla, who gives you this class, when defeated.
