Final Fantasy X Side Quests

Remiem Temple and Optional Aeons

Final Fantasy X has three optional acquisitions: , , and the . They are not three unrelated errands. and are both prerequisites for opening the chamber at Remiem, and all three extend battle sequence leading to Yuna’s .

Aeon	Where	Requirements	Earliest practical window
Yojimbo	Cavern of the Stolen Fayth	Defeat Yojimbo, then negotiate and pay for his service	After reaching the Calm Lands and defeating Defender X
Anima	Baaj Temple	Airship access plus all six Cloister Destruction Sphere treasures	Late-game airship cleanup, after the Zanarkand return treasure
Magus Sisters	Remiem Temple	Own Yojimbo and Anima; Flower Scepter; Blossom Crown	After the airship, Anima, and Mt. Gagazet capture completion

Yojimbo

waits at the end of the Cavern of the Stolen Fayth route. Defeat him, use the teleporter to collect the side-room treasure, then point the teleporter north to reach the Chamber of the Fayth. Make sure it is not accidentally pointing down. >.>

When asks why you want his service, choose “To defeat the most powerful of enemies.” That one-time answer favors his best attack against bosses and superbosses, which is where is actually useful. He then asks for 250,000 Gil. The easiest and least error-prone option is to pay him what he’s asking and give him a name. Bargaining does not make perform worse after recruitment. If cash is tight, a careful negotiation can hire him for 190,350 Gil.

Optional: bargain down to 190,350 Gil

Offer 125,001 Gil, then 112,501 Gil, then 141,751 Gil, and finally accept at 190,350 Gil. Pause for several seconds before entering each new offer; racing through the bids can change how the sequence resolves. If an offer is rejected, you can return and begin the negotiation again without damaging later compatibility. Paying triple the initial asking price can add two , but 750,000 Gil for that bonus is unlikely to be an affordable luxury for you on your first (or even 5th) visit.

is a relationship with a sword budget

does not accept direct attack commands. His hidden compatibility with Yuna, the amount you pay, his gauge, the target, and your original recruitment answer all influence what he does. Good attacks improve compatibility; paying nothing, dismissing him immediately, or letting him be KO’d hurts it. can defeat almost anything, but no sensible route should describe it as guaranteed. Save before a battle if your strategy depends on it.

After hiring him, teleport back to the entrance and save. Grab the from the side path outside the cavern if you have not already; it begins Auron’s Masamune route.

Anima

is at Baaj Temple, the submerged ruin from the opening. Use the airship Search command around X 11–16, Y 57–63 and select the new Baaj destination.

Baaj Temple and
Step	Action
1	Save, jump into the water, and swim toward the temple to fight Geosgaeno with Tidus, Wakka, and Rikku.
2	Protect against and KO if you can. Do not land the finishing blow while Geosgaeno has swallowed a character; its final spit can deal 9,999 damage to the whole party.
3	After the battle, dive into the southern alcove and search the bottom for the hidden Onion Knight chest. It requires the Celestial Mirror.
4	Swim through the northeast passage and enter the temple.
5	Open the two antechamber chests for four Mega Phoenixes and a .
6	Examine all six statues. Each one lights only if you opened the matching treasure chest in Besaid, Kilika, Djose, Macalania, Bevelle, or Zanarkand. The Cloisters and Destruction Spheres checklist gives the exact chest and route for each seal, including the forced Bevelle and the airship-only Zanarkand return.
7	When all six seals light, the front barrier opens. Enter the Chamber of the Fayth and receive .

This is kinda creepy, but whatever. You get a cool out of it.

Remiem Temple

Once chocobo riding is available in the Calm Lands, ride back toward the southeast entrance and examine the on the ground. The chocobo jumps to the lower path leading across the bridge to Remiem Temple. Save before starting the sidequests, pick up Al Bhed Primer XXIV outside, and then decide whether you want the race, battles, or both.

Chocobo race and Cloudy Mirror

Examine the sphere beside the champion chocobo on the west side, then speak to the chocobo on the east side. Reach the finish before the champion. Your first win always gives the Cloudy Mirror and replaces the ordinary chest-count prize for that run.

On later victories, each special prize can be won once. Open the target number of chests without touching a pole:

Chests	Prize
0 or a pole hit	Potion
1	Elixir
2	Megalixir
3	Wings to Discovery ×30
4	Pendulum ×30
5	Three Stars ×60

The four-chest reward is exactly enough to customize once. If Kimahri knows Steal and you collect the 30 before Mt. Gagazet, guarantees the rare two-sphere result every time his Steal succeeds against Biran or Yenke. It does not improve the shrinking chance that repeated Steals will succeed, so choose an armor you are willing to keep.

The champion changes routes as you open chests quickly enough. For the five-chest prize, the first four pickups need to be crisp so the opponent commits to its longest route. Six chests is not a legitimate target. Take the Cloudy Mirror to the lost-family crystal in Macalania Woods to restore the Celestial Mirror.

Belgemine’s aeon battles

only offers Yuna already owns, and Yuna cannot summon the same is using. Losing or escaping does not cause a Game Over. Summon an that absorbs the opponent’s element when possible, use elemental Black Magic to heal it, raise useful stats with Cheer, Focus, Reflex, or Aim, and Shield against incoming Overdrives. Save between fights. I kinda recommend it. ;)

If you missed both key items at earlier encounters, awards instead of and awards instead of . If you already have one but not the other, awards whichever one is missing instead of the .

Belgemine's aeon	First-win reward	Repeat reward	Progress effect
Valefor	Lightning Gem ×4	Power Sphere ×4	Opens Ifrit; a missing Summoner's Soul or Aeon's Soul can replace this reward
Ifrit	X-Potion ×30	Mana Sphere ×5	Opens Ixion; if both key items were missing, Aeon's Soul replaces this reward
Ixion	Chocobo Feather ×10	Power Sphere ×8	Opens Shiva
Shiva	Mega-Potion ×60	Star Curtain ×6	Opens Bahamut
Bahamut	Flower Scepter	Mana Sphere ×8	One of the two Magus Sisters seal items
Yojimbo	Shadow Gem ×8	Power Sphere ×10	Required before Belgemine offers Anima
Anima	Stamina Spring ×60	Mana Sphere ×10	Required before Belgemine offers Magus Sisters
Magus Sisters	Shining Gem ×40	Power Sphere ×12	Lets you send Belgemine for the Moon Sigil

For the last fight, I opted not to play fair at all. A sufficiently developed can erase the Sisters with . If that is no longer true for your party, target Cindy first because she can heal the group, then Sandy, then Mindy.

After defeating the , send to receive the . If you decline, you must defeat her Sisters again before she offers another chance. The sigil completes Yuna’s Nirvana.

Magus Sisters

The sealed door behind requires all four of these conditions:

Own .
Own .
Receive the by defeating at Remiem.
Receive the by capturing at least one of every capturable fiend assigned to the Mt. Gagazet region, including the cave and underwater areas, then speaking to the Monster Arena owner.

Use the and at the door to open the Chamber of the Fayth and receive Cindy, Sandy, and Mindy as one three-member summon. You cannot give the Sisters direct conventional commands or teach them new abilities. Name all three, then immediately re-enter the chamber for a .

The source boundary matters here: the belongs to Mt. Gagazet capture completion, not to finishing the Mt. Gagazet story sequence. If the Arena owner does not hand it over, compare your capture list against the Monster Arena checklist rather than revisiting the mountain blindly.
