Ninjas are extremely fast and can throw all kinds of items, but their real power lies in the fact that they get two attacks each turn. It's best to only equip them with ninja swords, however, as you won't inflict as much damage consistently with any other type of weapon. Their Abandon and Sunken State abilities make them extremely difficult to kill.
Prerequisites: Lv.2 Oracle
Weapons: Knife, Gun
Armor: Hat, Clothes, Robe
For serious battles, Mediators are practically useless, as the probability for abilities such as Invitation to work are extremely low. However, their Brave & Faith raising abilities are somewhat permanent, and their Invitation ability is the best way to obtain new units for your party.
Prerequisites: Lv.2 Priest
Weapons: Rod, Staff, Dictionary, Stick
Armor: Hat, Clothes, Robe
Oracles specialize in inflicting bad states on enemies. Since they're low on both HP and attacking power, they're not worth a whole lot to your party, except as a secondary force.
Prerequisites: Lv.8 Squire, Lv.8 Chemist, Lv.4 Summoner, Lv.4 Mediator, Lv.4 Geomancer, Lv.4 Lancer
Weapons: None
Armor: None
Mimes don't have any abilities to learn, nor can they be equipped with any sort of items. They simply mimic your other units' actions during battle. With proper timing, they can be a real asset, but by the time you satisfy all the prerequisites you probably won't even need one.
Prerequisites: Lv.4 Geomancer, Lv.4 Lancer
Weapons: Cloth, Women's Bag, Knife
Armor: Hat, Clothes
The Dancer has all kinds of attacking techniques that affect every single enemy in the battle, no matter where they are. Unfortunately, they don't seem to dish out a great deal of damage to any individual enemy. The Last Dance ability, which resets all the enemy's CT to zero, is probably the most useful.
Prerequisites: Lv.4 Mediator, Lv.4 Summoner
Weapons: Musical Instrument
Armor: Hat, Clothes
The Bard is the white magic counterpart of the Dancer. All of his abilities cure or heal your units in a similar manner as the Dancer.
Prerequisites: Lv.4 Priest, Lv.4 Wizard, Lv.3 Time Mage, Lv.3 Oracle
Weapons: Dictionary, Stick

The calculator is the ultimate magician's job. Despite being painfully slow, you'll have almost all the Priest, Wizard, Time Mage, & Oracle spells you've previously learned available to cast. What's more, they take zero MP and charge time to execute! The down side is that they take a long time to build up.
