Below you will find a basic introduction to the classes in Final Fantasy XIV: A Realm Reborn. For something more in-depth, expert recommendations and a brilliant leveling guide, my current recommendation is to pick up a copy of this FFXIV Class Guide. It blows pretty much anything else I’ve seen online clean out of the water.
To change your class in Final Fantasy XIV is as simple as changing what weapon you are equipped with. You can find NPC venders all around Limsa Lominsa selling Rank 1 weapons for each class and thanks to having substantial inventory space there is no harm in stocking up on each classes’ weapon early on.
The various Final Fantasy XIV classes available are grouped together under certain disciplines. Your combat centered classes fall under Disciples of War, crafting classes under Disciples of the Hand and gathering classes under Disciples of the Land.
What follows is a brief overview of the various FFXIV classes and the styles they play in. A list of skills, traits, abilities and spells for each differs (see also ffxivclasses.com for more details).
The Final Fantasy XIV classes are categorized under disciples and are currently as follows:
Disciples of War – Archer, Gladiator, Lancer, Marauder and Pugilist
Disciples of the Hand – Alchemist, Armorer, Blacksmith, Carpenters, Culinarian, Goldsmith, Leatherworker and Weaver.
Disciples of Magic – Conjurer and Thaumaturge
Disciples of the Land – Botanist, Fisher and Miner
Final Fantasy XIV Guides to each of the disciple can be found in most forums and community sites and will be added here shortly as well.
