Avatars
Once you become a Summoner (SMN — through the Summoner Job Quest at Level 30), you have access to various avatars who can be summoned at will. Summoning an avatar can bring great help in battle, whether it's as an extra fighter or simply to divert aggro away from other party members. Carbuncle is the first, joining you when you initially begin levelling your Sumonner. Once your Summoner hits Level 20, you can obtain other avatars by doing the Avatar Quests.
Carbuncle
The Carbuncle is a ruby that brings good luck to its owner. It takes the form of a small, furry creature that shows the way to the other avatars.
Ifrit
A blazing incarnation wreathed in the flames of retribution. Ifrit aids the summoner with its command over heat and fire.
Shiva
The queen of winter, said to have dominion over the glaciers of the north. Shiva aids the summoner with her command over cold and ice.
Ramuh
A secretive hermit said to be hoarding the wisdom of ages. Ramuh aids the summoner by using his staff to call forth electricity and lightning.
Titan
A legendary giant said to bear the world in its arms. Titan helps the summoner by shifting earth and rocks with its enormous strength.
Leviathan
A great serpent said to rule over the rivers and the seas. Leviathan aids the summoner with its command over waves and water.
Garuda
The queen of avians, said to soar through the heavens on immeasurable wings. Garuda aids the summoner with her command over air and wind.
Fenrir
A massive wolf heard howling at the moons of Vana'diel. Fenrir offers strength in his damage as well as his ability to raise stats in parties. Fenrir aids the summoner with his command over dark energy.
