2	Head left and climb down the ladder in the middle of the room.
3	Destroy the top three blocks on the far left to lower the bridge to your level.
4	Cross the bridge and destroy the barrel for 1x (Got it:). It prevents Stop. Don’t you wish we had it two main battles ago?!?
5	Cross back and climb down to the bottom.
6	Use the purple canister to weaken the enemies, then finish the fight.
7	Destroy the remaining blocks on the left to lower the next bridge and cross it.

5	Cross it, climb down the ladder, and take the doorway on the left.

The music puzzle

The room on the left plays the target notes. In the pillar room, destroy the following number of segments:

1x green
3x blue
4x red

Enter them in green, blue, red order. If the door does not open, leave through the doorway on the right and return to reset the puzzle.

Activate the central elevator
Step	Action
1	After matching the notes, take the newly opened southern doorway.
2	Follow the outside path and press the control switch at the end. This activates the final bridge between the First and Third Towers and the elevator to the central structure.
3	Enter the nearby doorway and step onto the triangular elevator pad.
4	Ride to the top, return to the Second Tower, restore the party, and SAVE.

Prepare for the central structure

Once you take the central elevator down and enter the structure, you are committed to . You can backtrack to the Second Tower save point and the after that fight, so these are not three uninterrupted bosses.

For an on-foot party:

Equip wherever possible. Otherwise prepare or .
Give the party or for the boss items. MOMO is not available here, so is not an option.
and make the damage phases much shorter.
I used Jr., Shion, and chaos. KOS-MOS also works if you give her strong non-Beam or Ether options.

If you plan to use A.G.W.S. units, equip , , and . Use W-ACT-capable weapons; the final form is airborne, so every unit needs a ranged option. Fighting on foot avoids repair and status-management problems, but a properly equipped A.G.W.S. party is also viable.

Optional: If you need supplies, weapons, A.G.W.S. equipment, or the Segment 14 you skipped earlier, return to the Third Tower entrance and take the doorway on the right. Cross into the First Tower, go down the chute on Floor 6, and use the lower-right exit to reach the . You still can’t leave, so you don’t really need to bother talking to Matthews.

When you are ready, return to the bridge between the First and Third Towers. Step onto the elevator with the three colored lights, ride it down, and enter the central structure. Watch the freak show. He prattles on for a while, then Shion says, “Huh?” For some reason I found that funny.

Simeon

Boss Fight: Simeon

HP / Type	8400 HP; Mechanical.
Special	Aird targets the character shown during the “frail” taunt. Guard with that character; after Aird lands, its Ether Defense drops and creates your best damage window. Below half HP it uses Aird, Boost, and more often. Its late wide-beam attack hits the full party.
Steal	; rare .
Weak / Absorbs	No weakness. Fire, Ice, Lightning, and Beam damage are reduced by about 50%.
Reward	32000 XP; 220 T.Pts; 200 E.Pts; 180 S.Pts; 0G.
Drops	; rare .
Strategy	Steal both circuits first. Jr., Shion, and chaos work well with non-Beam attacks. Build Boost, defend the character marked for Aird, then unload strong Ether or non-elemental attacks while its Ether Defense is down. Heal before it crosses half HP. A.G.W.S. units are viable with and , but the on-foot route avoids repair and status-management problems.

Save before the last fight

After falls, you are treated to (subjected to?) more cutscenes. When you regain control, do not talk to the weird guy dressed in purple with the plague doctor mask yet.

Recover after
Step	Action
1	Backtrack to the Second Tower.
2	Restore HP and EP at the save point and save your progress.
3	If you used A.G.W.S. units, continue back to the and repair them in the hangar.
4	Equip . Without it, cover Stop and Confusion first, then Attack Bind and Slow.
5	Make sure every active character can steal. The and are permanently missable.
6	Return to the central structure and talk to the masked figure.

Ein Rugel and Doppelwogel

This is one continuous battle. transforms immediately when its HP reaches zero, so steal the before finishing the first form.

Boss Fight: Ein Rugel

HP / Type	3600 HP; Gnosis.
Special	Binding Force inflicts Attack Bind on the party. Sonic Frost damages the party and can inflict Slow. Specter Wave inflicts . It can put an A.G.W.S. pilot to Sleep and can raise its own Physical Attack and Speed.

Drops	Rare ; no normal item.
Strategy	Steal the before dealing serious damage. neutralizes most of the fight; otherwise clear Attack Bind immediately with or . Use strong physical, Fire, Spirit, or Beam attacks, and remove its Physical Attack or Speed buffs if they become disruptive.

Boss Fight: Doppelwogel

HP / Type	4400 HP; Gnosis.
Special	The transformed boss is airborne, so close-range attacks cannot reach it. Chaos Arrow can inflict Confusion, Flare Wing inflicts , and Shadow Wing inflicts Stop on characters or Engine Stop on A.G.W.S. units.

Reward	24000 XP; 180 T.Pts; 160 E.Pts; 80 S.Pts; 0G.
Drops	; rare .
Strategy	Steal both items immediately. Use Far physical attacks, Spirit, Fire, and Ice; Jr.’s guns are particularly useful. Cure Stop and Confusion at once because a fully Stopped party is a game over. A.G.W.S. units need ranged weapons, , and before they are safe here.

Albido can show me the world. “Shining, shimmering, splendid! Tell me, princess…” Oh wait. Sorry. I got sidetracked.

After the battle, watch the cutscenes until you regain control. The next route starts with the Emails, shops, Segment rewards, and optional returns that open after the Song.
