To unlock the Onion Knight as an option for any given character, that character must be a level six Chemist and
a level six Squire.

During random battles (not
story-driven battles), getting experience and JP are vital to the growth of your characters. Since enemies in random battles can almost always be handled rather easily by your party (as they grow with the strength of your party), you can eliminate all but one member of the enemy party rather easily. Leaving that enemy alive, you should then have your characters attack one another, healing with Chemist skills and White Magic if you can, until you can no longer survive without killing off your party. Then, go after the final enemy and eliminate it to finish the battle. By doing this, you can create experience and JP you wouldnt have gotten in the battle otherwise, lessening the amount of random battles youll have to fight to build your characters levels.

If you have a Chocobo in your party, youll no doubt know that they have Choco Cure, a useful skill that can be used over and over again. Choco Cure restores some of the Chocobos HP, as well as characters in front of it, behind it, and to the left and right of it. If you try executing the hint entitled "Friendly Fire", having a Chocobo in your party to heal characters grouped together each round will allow you to survive the fight even longer, building experience and JP levels even higher.

Although its tempting to immediately branch out from the Squire job, stay with the job until you earn enough JP to purchase the JP Boost skill. With this equipped on any other job, JP earned in battle will be increased significantly, allowing you to acquire skills for other jobs more rapidly than you otherwise would have been able to.

There are two new jobs in this release of the game that werent in the original PSX release - Onion Knight and Dark Knight.

Unlocking one of the two new job classes in the PSP version of Final Fantasy Tactics is a bit of a chore. The Dark Knight has many pre-requisites to unlock, but once thats done, youll have a powerful job on your hands.

To unlock the Dark Knight class, you must completely master the Knight and Black Mage classes - that is, learn each of their skills. Also, achieve the eighth level with the Dragoon, Geomancer, Ninja, and Samurai jobs. You must also must have killed twenty enemies in battle to the point that the enemy disappears from the battlefield (three rounds).

Below are a list of all of the base jobs in the game, and how to unlock any given characters ability to use said job.

* - Only males can be Bards.

** - Only females can be Dancers.

If you have a Black Mage, have him or her learn the spell Toad. Then, transform all of the enemies on the field into toads. Kill any enemies that arent able to be turned. Then, you can attack and heal your own party to build experience and JP for as long as you want with no threat from the enemies. When youre done, you can then kill the toads for an easy victory.
