Why are we even climbing this tower? We could have done a "Gran Pulse Miracle" and hitched a ride on one of those flying enemies and flown all the way to Oerba. Thats what I, Cymbeline, whould have done. That would have saved us hours of walking.
Taejin's Tower Continued Edit
As you climb the stairs to the third tier, open the treasure sphere here for the Simurgh (What the Hell?) then continue up. Head over to the next room and examine the statue to open the way forward. I guess you can just twist and turn the tower as much as you like to make a way forward huh. When you head out turn to the right and open the treasure sphere here for Metal Armbandx2. Now head around and ride the elevator up to the Fourth Tier. Head out the area towards the Save Station and save, then head around to the end to the end of the circle and open the treasure sphere for Glass Orbx2. Now head through the door to your right and ride the elevator up to the Fifth Tier. Once here, head out the exit to the left and open the treasure sphere here for Ancient Bonex9. Once you have that head over to the opposite side of the room and activate the statue to take on Mark Mission 24. The mark: Mushussu is located to the left of your team.
With that taken care of, ride the elevator down to the Fourth Tier, then head all the way across to the other side, passing through the elevator, and all the way to the end of the half-circle for a treasure sphere with a Gale Ring. Turn around and go into the room to your left and head all the way to the left wall and open the treasure sphere here for Rainbow Ankletx2. Then take the elevator up to the Sixth Tier.
On the Sixth Tier, run down and accept his mission, then head out and into the next room to your left. Activate the statue and the towers will rotate. Head out of the room and enter the room two doors down. Defeat the Vampire and open the treasure sphere in front of you for Tear of Woex4, then open the treasure sphere by the stairs going down for the Unsetting Sun. Save as you go down the stairs and challenge the Mark.
After he's taken down, open the treasure sphere in front of you for a Librascope. Then head forward into the next room, and accept the next mission. If you want you can also take out the Tyrant enemy (Weak to Lightning). Head back to the Fifth Tier and challenge the next mark: Penanggalan. (She's in the room furthest away from the stairs)
With Penny gone we are done with all the mandatory Mark Battles. But the way didn't open. Huh, well I guess the best thing to do would be to go the the Fifth Tier and look for another statue. Go back to the stairs, then down to the Fifth Tier and out to the hallway. Here you'll get a scene with the Fal'Cie again. This guys really getting on my nerves...so lets finish this! Go to the end of the hallway and activate the final statue to open the way to the Cloven Spire. When thats done, follow Fang into an area with an elevator and ride it down to the Fourth Tier. Now run to the main elevator on the Fourth Tier and ride it up to the Sixth Tier. Once here head out the right side of the elevator and enter the door guarded by the Vampire. Enter the room and take out the enemies. Then open the two treasures spheres in this room for Tear of Remorsex8 and a Clay Ring. Now just make your way to the elevator in the next room. I advise against fighting the three Vampire's here to avoid a headache.
Once on the Cloven Spire its time to develope for a Boss Fight. Max out your character Ravger and Sentinel roles, then working on the last role they have left. Now would be an okay time to upgrade either Hope's or Vanille's Weapon, but you don't have to, at least not yet. Your also going to want to edit your paradigms:
Before you face off with the Fal'Cie be sure to set Bully as your active Paradigm. Your Accessories should be fine at this point.
After the battle Dahaka vanishes, never to be seen again. and an elevater leading to Oerba appears. And it turns out we freed the statues for the "horror" that was Dahaka. We also get to see whats happened to Oerba. Turns out the flowers as far as the eyes can see isn't there anymore, its all crystal now.
From where you start, head to the left, ignoring the path leading to the elevator to Oerba and open the treasure sphere for an Ethersol. Continue around sticking to the wall and open the treasure sphere you run into for Frostbane Broochx2. Continue along the wall and activate the statue you see to call an elevater, that will take you down the the Seventh Tier. On this tier go around to the right of the lift (I'm trying something new) and activate this final statue. This will connect the central lift to all tiers of the tower. Head out of the room and follow to path to the central lift opening the treasure sphere with a Collector Catalog. Now head up to the Spire and take that other lift down to Oerba and our final stop on our trip through Gran Pulse.
