Final Fantasy XIII-2 Walkthrough Part 4: Oerba

As soon as you arrive in Oerba, turn around and use Moogle Hunt to find a Giant Egg Fragment. Then proceed north and use Moogle Hunt again to find a Temporal Rift. Searching the Temporal Rift will begin another puzzle.

Temporal Rift Puzzle

In order to solve this puzzle, you will have to collect like-colored gems in the shape of a constellation, which basically looks like a star. Start at the top left corner. From here, collect the three gems in the second row from the left, then move diagonally up and to the right to get the next one. Move up one more to collect the second of the three gems in the line, then go right to get the next. Move diagonally up and to the left to get the next gem in the sequence, then proceed to the final gem in the upper right corner to complete the puzzle.

 

Your reward for completing this Temporal Rift puzzle will be the Time’s Stardust Fragment. You will also have unlocked a new section of the Oerba map. Look around for a billboard. There will be a broken section of wall blocking off the path underneath of it. Proceed here and jump over the broken wall piece to continue onwards, and then follow the path to the right. Turn around and head south to reach a staircase, which you should follow downwards until you find Chocolina.  

The house to the south of Chocolina contains the map of Oerba, so you should grab that while you’re here. After you get the map, head north and search for another Temporal Rift. Perform Moogle Hunt to reveal the Rift and jump in to solve another puzzle.

Temporal Rift Puzzle

This puzzle is similar to the last in that you must collect a series of gems in such a pattern that your path forms a picture. This time around, however, you must form two different pictures. The first of the two images is of a Nekton (the small, insect-like creatures that you fought in New Bodhum.) The center gem and the gem to the left connect together to form two of the Nekton’s feet, and the third gem on the bottom row connects diagonally to the gem on the second row. That gem then connects upwards to both the left and right forming the Nekton’s wings.

The second image will be of a Nekton from a different perspective. The two gems on the lower left of the screen will connect upwards to the large cluster in the center. The gem sticking out of the top of the cluster on the right connects downwards to the gem on the right of the second row, while the gem in the top center of the cluster connects upwards and to the right. The last step in forming this picture is to connect the gem on the top left of the cluster to the gem directly above it, and then up and to the right.

 

You will receive a Time’s Shell Fragment for finishing the puzzle, and more of Oerba will be restored, allowing you to proceed further into the level. Double back to Chocolina and run up the slope north of her. When a path splits off to the left, take it. The path will lead you around to a staircase to the north, which you should descend, and use Moogle Hunt to find yet another Temporal Rift. You will have to make three pictures this time, but you will in turn restore the Oerba map to completion.

Temporal Rift Puzzle

The first of the images is pretty easy to connect. Simple follow the gems from the lower left corner of the screen to the middle, then up to the upper right. The gem in the upper center of the area needs to be connected. Then follow the gems in a zigzag pattern down, first to the middle right gem, then to the one directly below and to the left of it, and finally to the one in the lower right-hand corner.

The second stage of the puzzle is also pretty easy. Simply follow the gems around the perimeter of the area in a sort of messed up circle. From top left, head down to the second row, then diagonally down and right to the first row. Head right two squares to get the next gem, then upwards to the second row from the top on the right. Complete the top of the circle to proceed.

The third area is naturally the trickiest and most bizarre of the images. This image will be of a Lobo, a sort of wolf-like creature. Its tail rests in the gem in the upper corner protruding to the right. The gem two squares below this marks its back leg, while the cluster of four in the middle make up its body. From here, proceed around the hole to connect its head, then diagonally down and right twice to form its front feet.

 

You will obtain Time’s Coral Fragment and the Oerba map will be completed. Proceed to the area that you just opened up, to the right side of the map near the Gate. Keep going to reach the beach. Run along the beach to the left to get to the Deserted Schoolhouse area. Pause the game and level your characters up. A boss battle is about to commence. Run up the stairs and examine the Oracle Drive to begin a cutscene and herald the arrival of Caius Ballad, the villain Lighting was battling in the beginning of the game.

Boss Battle: Caius Ballad

Caius is a dangerous boss and the biggest threat you’ve faced so far. Use the Delta Attack Paradigm to whittle down his health while maintaining decent health yourself. Even as you defend against his attacks, you may have to use a Phoenix Down or two to restore lost party members. Caius will often focus all of his attacks on one party member until they are downed, so you can either choose to stagger along by feeding potions that party member’s way, or go all out and attack until you need to revive your party using Phoenix Downs.

 

After surviving the battle with Caius, collect the Artefact of Origins and watch the ensuing cutscene. The path to the Gate is now open, but you should make sure to drop down through the broken skylight of the building before going through to find a chest. You may now also use Chocobos in this area, which can be helpful for finding a hidden Fragment. Head back to the Village Proper area and summon a Chocobo. There will be a gap nearby that only a Chocobo can cross, so hold down O/B to jump it. Then use Moogle Hunt to reveal the Graviton Core Gamma.

Now that you’ve found the hidden items in the area , proceed to the Gate and follow it back to Yaschas Massif.
