Adepts of the art of arcanum derive their might from symbols of power born of geometric techniques hailing from across the southern seas. Held within occult grimoires, these symbols lend shape to the arcanist's aether, thereby allowing him to produce myriad powerful spells.
Using the selfsame symbols to unlock the latent power contained within gemstones, arcanists are also able to summon forth the familiar known as Carbuncle to carry out their bidding.

With a bow in hand and a quiver on his back, the archer strikes at the enemy from afar. In Eorzea, two schools of archery have risen to prominence: that of the longbow sentries of the Elezen military, and that of the shortbow hunters among the Miqo'te.
Archers constantly assess the battlefield in order to determine the most advantageous ground from which to loose their arrows, as well as the nature of the shaft, point, and fletching best suited to their foe. It is said that master archers are capable of showering their targets with a veritable deluge of death well before a counterattack can ever be mounted.

Conjury calls upon the elements of earth, wind, and water and concentrates them to a potency at which spells can be weaved. Through practiced meditation on the essences of creation, conjurers draw forth and absorb aether from their immediate surroundings. A wand or cane made from unworked wood is then utilized to focus the aether until it manifests as the desired spell.
Versed also in magicks that restore and strengthen, conjurers are regarded as accomplished healers.

Gladiators specialize in the handling of all manner of one-handed blades, from daggers to longswords, be they single- or double-edged, straight or curved. Tracing their roots to the Coliseum, where the roar of the crowd reigns supreme, these melee combatants have learned to seamlessly flow between attack and defense in a dance that delights the eye.
Making use of their skill with the shield, gladiators can also draw the attention and attacks of an enemy upon themselves, thereby protecting their comrades from harm.

The lancer is a master of polearms—weapons which have evolved from humble hunting tools. In former times, the longspear saw the most widespread use, due in great part to the influence of the proud lancer legions of Ala Mhigo. The lancer's weaponry has since expanded to include other lethal implements such as the halberd and trident.
While it is no easy task to wield a polearm as if it were an extension of one's body, those who master the lancing arts come to be as a raging storm before their enemies, capable of delivering a barrage of devastating thrusts and slashes.

Marauders are combat specialists whose weapon of choice is the greataxe—a fearsome arm long associated with Eorzea's pirates. Their approach to battle is one of brute force, as they rely on pure strength and good steel to crush enemies and sunder weapons.
They are highly sought after for their ferocity and intimidating presence, and are often employed to hunt down monsters plaguing the land or to turn the tide of battle between warring nations. Skilled marauders have been known to take on entire packs of slavering beasts and emerge with little more than a few scrapes and bruises.

The path of the pugilist is one of incessant training aimed at mastering the traditional techniques of hand-to-hand combat. Though pugilists command formidable power when unarmed, they are wont to use metal, leather, and bone weaponry to maximize their destructive potential.
Their preference for fighting at close quarters makes negotiating distances an absolute necessity. Many among them accomplish this by avoiding burdensome armor, allowing for maximum mobility while they move in for the kill.

In the hands of a skilled practitioner, thaumaturgy can be a force of terrifying destruction. At the heart of this school of magic lies the ability to call forth and command the latent aether within oneself through deep introspection.
To then mold that aether into sorcery, the thaumaturge makes use of a scepter or staff, within which is housed a medium—a natural stone imbued with magical properties. Thus armed, the thaumaturge is capable of wreaking considerable havoc via ruinous spells and curses.

Fishers are the harvesters of the realm's marine and freshwater animal resources.
The trade rose to prominence in the nation of Limsa Lominsa, owing to the plentiful waters upon and around Vylbrand island. Be it from the shore of a sea, the bank of a river, or the deck of a boat, Eorzea's anglers must constantly account for a wide range of factors to optimize their success, including season, time, place, tools, and bait.
