Chapter 13: Mechonis Field Walkthrough

Fallen Arm

Objectives
1 Get the Piezoelectric Unit
Retrieve the Piezoelectric Unit.
Linada needs your help to stabilize Seven's condition. Head north of the village, following the quest marker, to find the needed Piezoelectric Unit. An elite Mechon guards the loot, so take care before engaging.
2 Sleep on It
Return to Linada and rest.
After returning the Piezoelectric Unit to Linada, speak to the nearby NPC and choose to rest. After the cutscenes, leave the village and proceed to **Mechonis Field.

Mechonis Field

Objectives
1 Conveyer
Use the conveyor belts to traverse the Mechonis.
Get around the Mechonis field using conveyor belts and lifts. Keep Shulk in the party and equip your members with Anti-Mechon weapons as nearly all enemies here are Mechon-type.
2 Unpowered lift
Repower the Lift.
You will eventually encounter an unpowered lift red-lit switch. Find the GF Main Power Switch, and later, the 1F Master Power Panel to continue ascending on the unpowered lifts through the area.
6 Find the Cylinder Activation Panel.
Another switch prevents you from ascending further, and this time it's in an area guarded by groups of Mechons. Defeat them and activate the panel.
7 Reactivate the 3rd Lift
Yet more lifts need repowering. Activate the panel in the 3rd Lift Engine Room, then follow the quest guide to the 3F Master Power Panel. You'll also have to climb the walls a bit.
10 Release the Bulkhead
As you ascend further, you'll find an Elite Mechon guarding a Master Power Panel. Defeat it and activate the switch to release the Bulkhead, then proceed to the Lower Bulkhead Bridge to ride the conveyor belt to the outside of the Mechonis.
13 Garrisoned Troop
Ascend via the Air Ducts
Keep following the path and you'll see a Machina that explains how to use air ducts to travel upwards. Do this and continue ascending until triggering a cutscene where the party takes a break.
14 High-Velocity Lift
Reenter the Mechonis.
Pass through the Patella Exhaust and the Upper Bulwark Bridge to reenter the Mechonis. You'll need to climb down to reactivate switches in two Power Supply Areas, then hit the final Main Power Panel Switch to reactivate the High-Velocity Lift.
16 Jade Face
Defeat Jade Face.
After entering the massive room you'll be attacked by Jade Face, who will use powerful sniping attacks. Take cover and advance forward until it's in range.

Tips and Strategies

Anti-Mechon Weapons

Weapons with Anti-Mechon in their names can dish out damage against Mechons without the Monado Art Enchant. This type of weapon is really helpful, and can allow Shulk to focus on damaging enemies without worrying about buffing his friends.

Mechon Weapons

Fiora's weapons can deal damage to other mechons without enchant (similar to Anti-Mechon weapons). Keep this in mind if you're going to include her in your party.

Boss Strategy Guide

Jade Face

jade face
A long-range boss that uses Sniper against the party. The battle ends as soon as Jade Face's HP falls to around 75%. Try to get in range with your attacks against Jade Face to end the fight quickly.

Build up the Party Gauge

The Party Gauge can be built up by attacking the Mechons in the vicinity. This will be extremely helpful when approaching Jade Face.

Hide Behind the Walls

Hiding Behind Walls
Hiding behind the walls will prevent Jade Face from sniping its target. Use the command feature to make your allies follow you if Jade Face targets them.

Use a Chain Attack to Approach Jade Face

Once a Chain Attack initiates, all characters will immediately approach the enemy regardless of distance. Once you can target Jade Face, initiate a Chain Attack and all your party members will surround Jade Face.

Boss Recommended Characters

The main problem with this fight is his long range sniper, which can slowly whittle down your party, or worse, defeat it. Tankers would be sitting ducks with their HP slowly going down against Jade Face's snipe attacks. It is better to rely on party members that have healing capabilities to sustain your party against his long range attacks.
