Avatar ( Final Fantasy XI ) Avatars are magical beings , some of which can be called forth by Summoners in " Final Fantasy XI " . Summoners can form a pact with an Avatar , enabling them to summon them in battle . Avatars can be encountered as both allies and enemies . Avatars of Vana ' diel . Sleeping Gods . There are eight avatars , known as the Sleeping Gods ( or the player - given name " celestial avatars " ) , represented on a stellar map . Each of them is tied to one of the eight elements of Vana ' diel and has a constellation in the night sky . The Avatars themselves sleep within Protocrystals hidden across the world , and if an Summoner defeats them in battle they may form a pact with the creature and are allowed to summon a part of their power ( in the form of an avatar ) within the normal world . It is said when the sleeping Avatars awaken they will return the world to its true state . However , this does not apply to Alexander and Odin , who are the subjects of a separate myth . The legend said that these Avatars were previously mortal beings , enlighten races , animals , and beastmen alike , that were transformed into Avatars and taken by Goddess Altana to heaven because she was touched by their action in their lifetime . They also appear as stars constellations in Vana ' diel ' s sky , with an important person or artifact in their legend as their notable and brightest star , along with notable beasts in Final Fantasy series like Behemoth and Bomb . Terrestrial Avatars . The five Terrestrial Avatars are mighty beasts tasked with protecting the mothercrystals . Unlike the Sleeping Gods , Terrestrial Avatars have a given purpose on Vana ' diel and are servants of Altana . Other Avatars . Atomos is an avatar that exists beyond the normal realms of reality . Residing in the Walk of Echoes , it is the devourer of time and serves to indiscriminately return dispensable time to the void . Smaller representations of it appear as Cavernous Maws strewn across Vana ' diel . These maws serve as portals for players to travel between different dimensions and times . Siren is a mysterious avatar referred to as The Forgotten Avatar who plays a role in the Rhapsodies of Vana ' diel storyline . She is not summonable by players . Player Avatars . ' Avatars ' is the name given to summons used by the Summoner Job . Each Avatar has its own unique abilities that allow them to fill different roles in groups , but they continually drain the Summoner ' s MP while summoned . This is known as their perpetuation cost . When the Summoner ' s MP reached 0 , the Avatar is dismissed . Elemental Spirits can also be summoned . They have a much shorter casting time but a higher perpetuation cost , and cannot be controlled through the use of Blood Pacts unlike most other avatars . It should be noted that whilst summonable Elementals are classified as avatars , those that are fought as enemies belong to the Elemental genus . Avatars are controlled via Blood Pact abilities . Blood Pacts are divided into two groups , and . Rage abilities are focused on dealing damage , while Ward abilities are focused on healing , supporting and enfeeblement . Using a Blood Pact from either group locks out the other abilities in that group for 1 minute . In addition to Blood Pacts , Summoners can use Astral Flow , which unleashes the avatar ' s full power . In this state , avatars do not drain MP , and the Summoner can command an Avatar to use its signature ultimate attack , such as Shiva ' s Diamond Dust . Astral Flow pacts consume all of the Summoner ' s MP to do so , but do not release the avatar because of the free perpetuation . The Avatars Odin and Alexander can only be briefly summoned while the summoner is under the effect of Astral Flow , performing their own powerful abilities before disappearing once more . Alexander and Odin uniquely cancel Astral Flow . As Enemies . Avatar is a genus of enemies that are seldom fought . Players usually fight them in battlefields to obtain them as summonable avatars or in battlefields relating to quests and missions . Almost all other instances of avatars in battle are when they are called forth by enemy summoners . In such instances , defeating the summoner will instantly dismiss the avatar . Some avatars also appear only to unleash their Astral Flow attacks when enemy summoners use Astral Flow , and are not seen for the rest of the battle . Shown here are enemies of the Avatar genus not listed above . Other appearances . " Dissidia Final Fantasy " . Ramuh and Carbuncle from " Final Fantasy XI " appear as automatic summons . " Final Fantasy Legends II " . Carbuncle from " Final Fantasy XI " appears as a summon . " Final Fantasy Trading Card Game " . Some avatars appear as cards .
