4When the elevator stops, head right and enter the next room.

The last return window

The corridor ahead contains four more enemy groups and can be reset by stepping through the far door and returning. This is the last useful farming loop and your last chance to walk back to the LocationThe cargo ship that becomes the party’s main transportation hub. for shops, A.G.W.S. repairs, the E.V.S., or unfinished sidequests.

Prepare for the final battles
StepAction
1Clear the four enemy groups in the corridor.
2If you want more levels or points, leave through the far door, return, and repeat the corridor.
3Every few rounds, ride the elevator back to the save point and save. The four forced elevator battles do not repeat.
4If you need the LocationThe cargo ship that becomes the party’s main transportation hub., return to the LocationThe late Proto Merkabah route area., take the brown shortcut door you unlocked, descend through the LocationThe laboratory floors within Proto Merkabah., and follow the catwalks back.
5Spend your remaining Tech, Ether, and Battle SystemBattle reward spent to extract Skills from equipment.. Restock healing and EP recovery items before making the final trip.
6Equip SkillPrevents Confusion. or SkillPrevents all status effects., Damage -10, and your best endgame skills. Prepare Shion to cast EtherShion: One-use-per-battle 9,999-damage attack against all enemies, earned after completing the Robot Part quest. in each of the two coming battles.
7Save one last time, return through the farming corridor, and stop before approaching the central structure beyond the far door.

I usually walked this corridor for a while, getting more and more powerful. In one wonderfully excessive run, everyone was over level 85 with every Skill and Ether before I went on. Around level 45 is enough for a comfortable finish if your equipment and abilities are in order.

Once you approach the central structure, the final sequence begins and there is no more ordinary exploration. Take a breath, make sure you actually saved, and then go ruin Albedo’s evening.

Continue with Final Battles and Ending.
