Djose Highroad and Temple
Save your game at the Save Sphere again before you continue down the Highroad.
You will encounter fiends down this road called Basilisks (shown below). They will cast Stone Gaze on party members which will petrify them. If all of your party members have the Petrify status its game over. Though that outcome is fairly unlikely, petrified party members will also not gain any EXP or AP, which means using Soft on them to remove the Petrify status is a must.
Alternatively, you can make use of Yuna’s Esuna spell to rid your party members of the status.
Continue down the road until you reach a chest that contains two Phoenix Downs. Just past the chest is an Al Bhed Primer (Vol. XI) laying just behind a pillar. Use the screenshot below to help you locate it.
Talk to all of the people that you pass for some items including a Soft Ring (very useful in this area), Ether, Hi-Potion, Mega-Potion, Variable Steel and a Bright Bangle (the treasure chest for this item is hidden off to the side).
There area a few more cutscenes and story telling when you reach the fork in the road.
Djose - Pilgrimage Road
There is nothing to gather on the Pilgrimage Road so just continue on to the temple of Djose. Talk to Lucil and the Crusaders as you pass.
Use the Save Sphere and save your game before you enter Djose Temple. You will also want to venture to the northeast side of the temple beside the shop to find a treasure chest. There are four Ability Spheres inside.
To the far left of the temple, past Lucil and the Crusaders with the Chocobo, is another treasure chest which contains 4,000 gil. Enter the temple when you’re done.
Make your way to the left and to the right of the stairway after the meeting with Isaaru. The room to the left contains a treasure chest with a Remedy inside. The room on the right side contains a treasure chest with a Mega Phoenix in it.
Djose Cloister of Trials
Completing the Cloister of Trials in the Djose Temple. The reward for completing the Destruction Sphere portion of this Cloiser is a Magic Sphere.
After completing the trials you will run into Dona and Barthello again. Try to leave the temple chamber to continue the story again. You will now have Ixion as another Aeon that Yuna can summon.
Go back inside the temple when Tidus awakens and enter the room to the left of the Cloister of Trials to find Yuna sleeping. Save your game at the Save Sphere and then re-enter the store/inn to grab the treasure chest at the back of the room. It contains a Switch Hitter.
The shop has some useful items that you may want to consider purchasing including the Rune Mog for Lulu, the Shimmering Blade for Auron and the Hyper Ball for Wakka. The Armor for sale all has the “Defense +5%” ability. You may have armor that is stronger than what the shop owner is selling but, if not, you can take this opportunity to buy some upgrades.
Head back towards the Y-intersection.
Djose - Pilgrimage Road
This time when you cross the Djose Pilgrimage Road quite a number of the people you speak with will have items for you.
The next section of the game takes place on the Moonflow.
