Tips and Strategies

Vision Timer

Vision Timer
You will notice that there is a number located on Shulk's vision. This indicates the seconds left until his vision becomes a reality. This will be incredibly useful for the last boss of this chapter.

Boss Strategy Guide

Apocrypha Generator

Apocrypha Generator
Similar to Gadolt, the Apocrypha Generator's main line attack consists of Ether-based moves. It can use Laser, which can deal around 2000-3000 damage to a single target, and it inflicts topple as well. Watch out for Great Laswer VI, and always ready your Talent Art Shield to block it. Also make sure to not let Apocrypha's aggro target you, so you can focus all your healing abilities on your tank.

Apocrypha Generator Recommended Characters

Shulk Icon Shulk Dunban Icon Dunban Riki Icon Riki

The Apocrypha Generator has a high amount of HP, and also has access to strong Ether Attacks. Shulk, Dunban, and Riki is the best set up against Apocrypha, due to their high Ether Defense and damaging abilities. Use Warn on Dunban, and let him take the Aggro if the Generator targets a different party member by selecting Blinding Blossom.

Yaldabaoth (Mechonis Core)

Yaldabaoth
He's going to be immovable through the fight. You can only hit him in the front, so don't waste your time trying to circle the map to increase the effects of Shulk's Chain Arts. He will also summon several Mechons during the fight, so eliminate them once they appear. You can take the opportunity to fill the party gauge.

Make sure to always stay in range against Yaldabaoth (except when dispatching summoned mechons), as he can use Chastise, which will seal your movement, stopping you from attacking him if you're out of attack range.

Bionis Slash X

Bionis Slash X
When you see a vision of the Bionis Slash X, immediately stop all attacks against Yaldabaoth, and focus on the three generators summoned on the area surrounding him. Do not panic, you have 2 minutes to destroy the generators, which should be more than enough.

Yaldabaoth Recommended Characters

Shulk Icon Shulk Dunban Icon Dunban Sharla Icon Sharla

Switch Sharla in for this fight. Her healing is needed against Yaldabaoth's heavy damage. You're also going to need Dunban to quickly eliminate the Mechons that gets summoned in the fight.
