Cloister of Trials The Cloister of Trials ( Original : ; International : ) is a feature of the temples of Yevon in " Final Fantasy X " . Each cloister is a large puzzle which players solve to advance to the Chamber of the Fayth . Solving a cloister involves such actions as pushing moveable pedestals , removing and replacing a variety of spheres — each temple having a sphere named after it , while all temples have Glyph and Destruction Spheres — or strategically activating or deactivating moving elements of the cloister ' s structure . No battles occur while characters are within the cloister . After each Cloister of Trials , the summoner Yuna obtains a new aeon . Cloisters of Trials are present in Besaid Temple , Kilika Temple , Djose Temple , Bevelle Temple , Macalania Temple and Zanarkand Dome . They are not present in the Cavern of the Stolen Fayth , Remiem Temple or Baaj Temple . The player can unlock the aeon Anima by obtaining all the secret chests revealed by Destruction Spheres , with the exception of Bevelle , in which the player obtains the item right before the Chamber of the Fayth ( as the party will not be able to return ) . Only summoners and their guardians are permitted to enter the Cloisters of Trials , as evidenced by Wakka ' s dialogue to Tidus at Kilika , the summoner themself may be excommunicated if any non - guardians accompany them . Two years into the Eternal Calm , the Cloisters of Trials have been rendered off - limits to everyone , but are traversed by the Gullwings upon the appearance of aeons corrupted by Shuyin . In Chapter 5 , the player can undergo the Gunner ' s Gauntlet in the Besaid Cloister of Trials by talking to the priest . Completing the Cloisters of Trials in " Final Fantasy X HD Remaster " earns the player trophies . List of spheres . Each Cloister of Trial has a treasure that can be uncovered with a Destruction Sphere . Collecting the treasure from all six Cloisters of Trials unlocks the path to Anima in Baaj Temple . Bevelle Temple uses the Zanarkand sphere , and glows blue . Baaj Temple uses the Besaid sphere , and glows blue . In the room in Baaj with glyphs for all the other temples , Zanarkand is represented with a Zanarkand sphere , glowing yellow , and Besaid with a Besaid sphere , glowing violet . The actual spheres underneath are the same , all that changes are the visual glow effects . Bevelle Temple using the Zanarkand sphere may have been a mistake . There is a purple sphere found within the game data with the " dark " elemental symbol inside it that is associated with Anima . This may be a sphere intended for the Baaj Temple , although the Baaj Temple does not have a Cloister of Trials . Strategies . Besaid .
