Chapter 13: Mechonis Field Walkthrough

Fallen Arm

1 Head to the Northern side of the village and get the Piezoelectric Unit.
There will be an elite mechon near the Piezoelectric Unit. Approach it with caution.
2 Return to Linada and give her the unit.
3 Talk to the lady standing nearest to your destination and agree to taking a rest.
4 Follow the quest guide to leave Fallen Arm and reach the Mechonis Field.

Mechonis Field

1 Use the conveyor belts to traverse the Mechonis.
Enemies will consist mostly of Mechons, so having Shulk is recommended for this area, especially if your allies don't have anti-mechon weaponry.
2 Head deeper inside the Mechonis Field, until you find an unpowered lift.
3 Follow the path ahead, then activate the switch located on the GF Main Power Switch.
4 Return to the Unpowered Lift (which is of course, powered now), and ride the lift that will appear after a few seconds.
5 Head to the 1st Floor and activate the 1F Master Power Panel.
6 Return to the branching path, then head to the area that is heavily guarded by the Mechons. Defeat them, then activate the Cylinder Activation Panel.
7 Go to the 3rd Lift engine room, then activate the panel in that location.
8 Go to the now-activated 3rd Lift, and use it to ascend the Mechonis Field.
9 Follow the quest guide and head to the 3F Master Power Panel.
You'll know if you're going the right way if you're climbing several walls.
10 You'll pass through your destination, but defeat the mechon that's guarding the switch. Then head forward and activate the master power panel.
11 Return tto the area guarded by the Mechon earlier, and activate the panel to release the Bulkhead.
12 Go to the Lower Bulkhead Bridge landmark (by walking or by quick traveling), and ride the conveyor belt downwards.
13 Follow the road until you see a machina, then stand on the air duct near him to jump upward.
Keep following the road until you find the 2nd air duct.
14 Activate the two Power Supply Panels.
15 Go to the 4th floor main power panel switch and activate it.
16 Make your way to the high velocity lift, and use it.
16 Defeat Jade Face.Jade Face

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

Shulk IconShulk Sharla IconSharla Riki IconRiki

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.
