Final Fantasy X/Yuna

Yuna is the game's female lead, and the majority of the game follows her and her guardian's journey from Besaid to Zanarkand Ruins in order to summon the final Aeon.

Background
10 Years before Final Fantasy X starts, Yuna's father (Braska), along with Tidus' father (Jecht) and Auron defeated Sin temporarily with the final summoning, resulting in a Calm that has caused Yuna to be somewhat famous throughout Spira. Now 17, she leaves her island home of Besaid (although born in Bevelle, Auron and Kimahri brought her to Besaid after her father's pilgrimage was complete) to follow in her father's footsteps with her (eventually) 6 guardians. Yuna's pilgrimage leads her through all of Yevon's major temples (and potentially some extra ones) where she must pray to the Fayth to receive and Aeon to help the party through their difficult journey.

Basic Fighting Style
Yuna is the most unique character, as she is the only one able to summon Aeons. Until you reach the end of her sphere grid, Yuna is a purely defensive character, learning only protective and regenerative white magic spells. Her low strength means that the only way for her to launch a useful offence is by summoning an Aeon. Yuna's stats are generally on par with Lulu's throughout the game, with poor offense and defence and low HP. Both characters make up for this with a high amount of MP, and good magic and magic defense. Although Yuna cannot quite match Lulu's excellent magic defense, her other stats are generally higher, most notably the considerably higher magic stat. As for the other stats, Yuna has good agility and evasion, but slightly below average accuracy.

For the monster arena and dark aeons Yuna will be an essential part of the team. Her ability to summon not only allows for powerful attacks, but can also be used to block powerful attacks that would otherwise wipe the party out. Her high magic stat gives an excellent base for her to become a powerful attacker, and a tour around Auron, Tidus and Wakka's routes on the sphere grid will both turn Yuna into a competent attacker, but also max out most of the Aeons' stats too. Lulu's grid is another good choice if one wants to make Yuna into a "Sage" Character, as Yuna's utterly superior Magic stat renders Lulu obsolete once Yuna learns some Black Magic (Either through Black Magic Spheres or a well-placed Teleport Sphere). Although Yuna's overdrive is useful, better is the special ability on her Celestial weapon that allows more damage as Yuna's percentage MP is higher.

Overdrive
Yuna's overdrive is Grand Summon. It will summon any available Aeon, but supply them with a full overdrive bar. After using this overdrive the Aeon's overdrive bar goes back to what it was before it was summoned, meaning that 2 overdrives in a row is possible if the aeon has full overdrive and is then grand summoned.

Celestial Weapon
Yuna's Celestial Weapon is the Nirvana, and is powered up by the Moon Crest, then the Moon Sigil. Obtaining the weapon will require the Celestial Mirror, as will powering it up.

Obtaining the Weapon
Clear the Calm Lands in the monster arena (i.e capture one of every monster there), and a chest will appear at the monster arena entrance. Open the chest (which you can only do if you have the celestial mirror) to obtain the weapon.

Moon Crest
This is located on the beach at Besaid Island. To reach it swim out towards the sea and go right (from the perspective of facing the island) and round a large rock face to get onto another beach with the chest that contains the moon crest on it.

Moon Sigil
Defeat all 8 aeons (both 5 regular and 3 secret) of Belgemine in Remiem Temple, and then choose to send Belgemine to receive the moon sigil. To be able to fight each aeon you must have first obtained it yourself, and can battle each aeon with only Yuna's other aeons.

Final Outcome
Power up the Nirvana with both Moon Crest and Sigil and the outcome will be
 * Weapon Effects:
 * Break Damage Limit
 * Triple Overdrive
 * Double AP
 * One MP cost
 * Does more damage when Yuna has a higher percentage of her MP remaining
 * Allows Valefor to break damage limit
