Cavern of the Stolen Fayth

You can complete the Cavern of the Stolen Fayth side quest during your first path through the Calm Lands, however it is recommended that you come back once your characters are much higher levelled. Yojimbo will cost you 200,000 gil to obtain and you can easily get by without obtaining him.

The Cavern of the Stolen Fayth is located at the Gorge Bottom just north of the Calm Lands. Save your game at the Save Sphere before you enter the cavern. Make sure to use your weapons with the “Capture” ability while you are down here if you have it to begin amassing the fiends that you need for the Monster Arena side quests.

The cave is fairly linear. Take the first pathway on the right that you come across to find a treasure chest that contains a Megalixir. Continue into the first main open area to continue the story.

You may encounter a Magic Urn while you are in the Cavern. You will receive an item from the Urn if you attack the correct eye. There is no way to know ahead of time which eye is the correct one - this is strictly a game of chance.

Take a right at the next pathway and you will find a treasure chest that contains a Lv. 2 Key Sphere. Going straight at the next intersection will lead to a treasure chest that contains a Fortune Sphere.

As you continue down the path you will find another treasure chest that contains two Mega-Potions and just off to the left side of the screen you will find Al Bhed Primer vol. XXV. Save your game at the Save Sphere near this area before you continue.

The next area leads to an encounter against an unsent summoner, Lady Ginnem. The summoner will initiate a battle against you and she will summon Yojimbo. Yojimbo is not too difficult to defeat. You can use Yuna’s Aeons if you are having difficulty. He has approximately 30,000 HP.

Step on the teleportation platform in the middle of the room to enable it. Stand on the platform facing forward and press X to warp into the Chamber of the Fayth.

Yojimbo will present you with three options:
- To train as a summoner.
- To gain the power to destroy fiends.
- To defeat the most powerful of enemies.

Choose the third option (“To defeat the most powerful of enemies”) as this will reduce the overall cost of Yojimbo in terms of gil. The price starts at 250,000 gil but you can haggle up to three times by offering Yojimbo less money. You must offer him at least 50% of what he is offering plus 1 to get him to lower his price.

- Asking price of 250,000 gil = offer him 125,001 gil
- Asking price of 225,000 gil = offer him 112,501 gil
- Asking price of 200,000 to 210,000 gil = accept that price as it does not get much lower.

You now have Yojimbo as a new Aeon.

Before you leave you can use the teleported to warp into the room on the left and the right before warping to the entrance. The room on the left contains a treasure chest with a Flexible Arm weapon for Rikku (which contains 4 empty customizable ability slots). The room on the right contains two treasure chests - one which contains an MP Sphere and one which contains two X-Potions.

Exit the Cavern of the Stolen Fayth once you are done.
