Instructions
Acquire Valefor at the Besaid Temple. Toward the beginning of the game, Yuna, one of the main characters, visits the temple. The game gives her Valefor during a cut scene, so no extra effort is required.
Speak to the characters inside Kilika Temple while Yuna is praying. After a little while, Yuna will finish praying and emerge from the temple doors with Ifrit.
Complete the Cloister of Trials at Djose Temple to receive Ixion. Inside the Fayth chamber, speak to all the characters and gain Ixion.
Fight Seymour in Macalania. As with the other Aeons, Shiva is granted to Yuna while she prays at the temple, but she doesn't show up until the battle with Seymour, where she is listed as "?????."
Solve the maze at the Bevelle temple by rearranging the spheres. At the end of the maze, find Yuna in the Chamber of Fayth, where she has been praying. Yuna receives Bahamut there.
Fight Yojimbo in the Cavern of the Stolen Fayth. After surviving the battle, Yojimo will offer the party treasures in return for money. After haggling, Yojimbo joins the group.
Go to the Baaj Temple by entering the coordinates in the airship. In the temple, fight Geosgaeno and proceed to the area with the six statues. Activate the statues, which requires the Destruction Sphere treasures from the other temples, including the Zanarkand temple, to recieve Anima.
Examine the flowing glyph on the door of Remiem Temple. If the party has the Flower Scepter form defeating Belgemine's aeon in Remiem Temple and Blossom Crown after capturing all the monsters in Mr. Gagazet and Gagazet Mountain Cave, use them on the door to get the Magus Sisters. The Magus Sisters cannot be obtained without Anima and Yojimbo.
