Release the elevator

Go slightly up and left to find the ever elusive save point. ;) Took a while this time, didn’t it?

The elevator only drops after you destroy all six safety clamps, one on each side across three levels.

Open SidequestSegment Address 9 is opened with Decoder 9. with Key ItemItem required to open Segment Address No. 9 , collect the Key ItemGive to Professor at Robot Academy; both arms give Throni Blade, and mark it . You can also open Segment 9 in the full tracker.

Backtrack to the save point and save.

Prepare for Gargoyle

The upcoming fight can be challenging. My party was around level 18. If you’re behind that or the last few fights have been ugly, this is a good time to backtrack to the five-Fairy farming spot and upgrade your Tech Attacks.

Use Shion, KOS-MOS, and MOMO unless someone else can steal. Equip KOS-MOS with the Character AccessorySlow Guard (Prevents Slow) and Shion with the Character AccessoryLost Guard (Prevents Lost). Make sure MOMO or your other healer has EtherShion: Medium HP recovery for all allies.. Gargoyle can inflict Lost, so extract SkillPrevents Lost. from the Character AccessoryLost Guard (Prevents Lost) for your healer if possible.

Reach the Gargoyle chamber
StepAction
1Take the released elevator to the lowest level.
2Three Gnosis circle the ring clockwise. Wait for a gap, slip in behind one, and follow their patrol if you want to avoid fighting them.
3At 9 o’clock, destroy the partition and the object behind it for 1x Veil ().
4Continue around to the elevator at 6 o’clock and ride it down.
5Head north, examine the panel to the right of the door, and press the button.
6Restore everyone’s HP and EP. Set Lightning Ethers, EtherMOMO: Once per battle, transforms MOMO into Star Wind form., Tech AttackMOMO: Transformed MOMO Tech Attack with a chance to steal a rare item., and your strongest Tech Attacks before entering the chamber.

Gargoyle and Oudogogue

If you kill off the little guys first, you’ll make Gargoyle more powerful. On the other hand, if you DON’T kill them off first, they will heal him and hurt you. So… I recommend going after the little guys.

Your A.G.W.S. units are powerful, but they’re really slow compared to your characters at this point. If they don’t work well for you, don’t be afraid to abandon them! A.G.W.S. WeaponOne enemy; Near; Slash; supports W-ACT. can do 400+ damage. After your mechs are badly damaged, discard them before they hit 0 FHP and continue on foot.

If this battle is too tough, load the most recent save, backtrack to the optional level-up area, and level up a bit. I just barely beat these guys with level 18 Shion, Ziggy, and chaos.

Watch the cut scenes and save when prompted. The next route begins on the Durandal and Kukai Foundation.
