~Obtain Anima~

This trophy will be near the end of the game as you'll be required to have the Airship to reach the temple holding Anima; however, there is also another set of actions you must do before you can reach Anima. The first thing you'll need to do is obtain the item in the six regular temples of Spira; Besaid, Kilika, Djose, Macalania, Bevelle, and Zanarkand. These items are obtained by utilizing the Destruction Sphere in each Cloister of Trials and opening the hidden chest. Note that you automatically earn the item in Bevelle, while you'll have to go back to Zanarkand and clear it a second time to obtain the item.

With that step finished; on the Airship use the search function and check the cloudy archipelago in the south-west portion of the map to find Baaj Temple. The coordinates should be anywhere between; X = 11 to 16, Y = 57 to 63. With the temple found, it's now selectable from the Airship List, so go there. You'll be in the area Tidus washed up in after his first encounter with Sin. Move along the narrow path and jump into the water, swim to the doorway, and defeat the giant fish that attacked him at the start of the game. With the enemy dead, go ahead and enter the doorways until you're in a room with a shield and six statues. Interact with each statue to activate it; when all six statues are active the shield will lower and you'll be able to enter the Chamber of the Fayth. If you've not obtained the item from any of the six temples, the statue will not activate and you will not be able to enter the Chamber of the Fayth. With the shield down, enter the Chamber of the Fayth, listen to the Fayth's story and afterwards you'll have Anima and this trophy.

See the Cloister of Trials Guide for specific temple details.
