If you have as many life fragments as you're allowed you'll get money instead. When you see a hill on the right going up ignore it and go straight to find a Life Fragment. If you look to the right you'll see a hole with an item, it's a Bahamut Tooth. For now follow the wall south to reach an alternate entrance to the zodiac temple. We'll actually deal with this area in a minute. Now return to the previous area, the barrier west of the NPC is gone and you can go through it to the Great Plains. Behind the bushes is a small cave with a Prison Key. Go up to the 3 stairs that lead to it and drop down the left side. Go back to where you fought the casters, and face east to see a door. Go around the right side of the wall with the fence and follow the wall to a little alcove with the war core. Once they're dead, you'll find another stone head to the west in a little alcove, break it. Try to use the walls to block some of them from shooting and blast them with Magic Beam. Continue forward to find an Ancient Lance. In this area head west until you see stairs on your right, go up them. Now head into the Zodiac Temple exit to the southwest, in the southwest corner of the map. Head straight north and a wing icon thing will appear on your map and you can talk to the NPC that spawns there. Follow the south wall east, you'll climb a hill with a Nature Bell on top of a body. At the start of the area, head straight southwest to a small alcove (more of the casters on the way). Their only ranged attack is charging up and throwing a bolt. For the white ones, use the Bearer's Magic Beam. For the black ones, switch to ergo and use his Dark Beam. Return to the start of the area and you'll encounter new enemies on the way. Just stay away and use Magic Beam like always.

He can also make a shock-wave, but if you are far away it won't hit. To avoid his charges, just stay far away from him. When he disappears just run away and it won't hit. It may charge at you and slam the ground you're on, or it will disappear and then land on top of you. When it opens up again get the Life Fragment to the north, and break the big stone head in the middle of this clearing. Go straight south all the way to the bottom of the area. Continue north, and when the room opens up get the Jian to the right. Now head up the stairs, and keep an eye on the right side and you'll see a green switch you can activate, go through the door to an area with a Core of the Fantasy in front of you, grab it and return to the 3rd wing. There's a Life Fragment to the right on the first big landing (past the 2nd set of stairs). You'll find a Gae Bolg in the small passageway. Stand on the right side, and then when he gets close dodge to the left side and jump up to the platform next to the stairs and run to the red flaming wall and get him to blow it up. Leave and return to respawn the guy, then let him come down to the 2nd set of stairs.

You need to lead the suicide guy into it, but he blows up when he's close to you so the 'challenge' is leading him to the red wall before he explodes. Continue up the stairs and keep an eye on the left wall, you should see a small red flaming section. Head up the stairs until The Bearer says something. Go forward and you'll see one of those red exploding guides spawn ahead, ignore him for now. Save and head to the 3rd wing, which is the eastern door on the 1st floor. No map here, the map is messed up and you can only see half of it, even when you scroll around.
