Yaschas Massif -010 AF- is the first location unlocked in the third episode of Final Fantasy XIII-2.
You left from Bresha Ruins -005 AF- and traveled through time to this new location, along with Noel and Serah.
Our Final Fantasy XIII-2 Walkthrough Episode 3 Yaschas Massif explains how to complete this region, and the quests that are given to you by the characters encountered in this zone. Before starting the game, you should know that the third FF13-2 episode is divided in two parts and each part features three zones that must be explored.
The first part of the third act is called Prophecy of Hope.
When you arrive in Yaschas Massif, you will unlock the Future Espier Achievement/Trophy.
Yaschas Massif is a dark place, affected by an eclipse, and it is important to know that in this area you can be safe as long as you stay in the light.
Check your objective on the map.
Objective 1: Head into the ruins
Pick up the sphere on the right because it contains 500 gil.
To the left is a hidden sphere. Send Mog after it and get the Metal Armband inside.
Now, approach the researcher and get the Map of Yaschas Massif. Talk to him again for a Live Trigger, then jump off the ledge to the right, and continue forward.
Move up, go left, and learn about Searchlights. Remember to run from one Searchlight to another, in order to avoid any confrontation; otherwise, you will be attacked by Behemoths. If this happens, the Behemoth will kill you, and it is impossible to defeat the creature right now.
Pick up the sphere on the left and the one you see on the right side of the canyon, and then continue forward, until you reach Chocolina.
Purchase or sell the items you dont need, then go east and pick up the Scars’ Gate Seal inside the prism to the left. The Scars’ Gate Seal allows you to travel back to Bresha Ruins -005 AF-.
Near the Searchlight, loot the sphere, and advance. There is only one path to follow here, and eventually you will reach the marked spot on your map.
You will see Chocolina, and to her left, a researcher. Make sure you purchase some Wound Potions from Chocolina. Talk to the researcher, but get ready because when the dialogue ends you will fight a boss, named Aloeidai
Objective 2: Defeat Aloeidai
Aloeidai is a powerful boss and you must keep in mind that you must finish the battle as fast as you can. There are two important phases.
During the first phase, use SEN/SEN/SEN to stagger Aloeidai, and when he is staggered, switch to COM/COM/COM to inflict as much damage as possible.
During the second phase, Aloeidai has a shield that will disappear when the boss is staggered. Use the same combinations, and make sure you have enough Wound Potions in your inventory. Use them and dont let the third party member die, especially if it is a medic.
Try to beat the boss before the third phase, or you will have to repeat the whole strategy.
You should use SEN/SEN/SEN every time the boss attacks, and COM/COM to deal increased damage.
After you defeat Aloeidai, Hope appears and a cutscene starts. For beating this boss, you will earn the Aloeidai Fragment.
Hope will escort you to the camp you will receive a new objective.
Objective 3: Secure access rights
Follow the ramp on the left and go up to loot two spheres, then go back and move towards the exclamation mark.
Near the stairs, to the left is a hidden sphere. Send Mog after it, then talk to the guard near the barrier.
Follow Hope and talk to him. Complete the Live Trigger and loot the sphere behind Hope for a talisman.
You will learn about the City of Paddra and the Farseers.
Continue to follow Hope and learn about the Oracle Drive, and how it works.
Watch the cutscene and take the Hollow Artefact from Hope.
You can talk to Hope again if you want; however, your main objective changes, and you must look for the gate.
Objective 4: Search for the gate
Follow the first set of stairs down and to the left you will find Cole who has a side-quest for you. If you complete it, you will receive a new fragment, called Amur’s Sphere, but to get it you have to find the old-model battery.
Secondary Objective 1: Find the old-model battery
If you go back to the starting area, you can get another fragment from Brenda. She offers the Miserys Bead fragment if you give her a behemoth fang in pristine condition.
Secondary Objective 2: Obtain a behemoth fang
Since these creatures are strong enough, you should come back here later, to complete this quest.
Right now, its time to move forward in the game. Access your map and go to the marked position, to open the gate.
Use the Hollow Artefact to travel to your next location: Oerba -200 AF-.
