Chapter 3 (Normal) Walkthrough Guide

Chapter 3 Overview

God's System
Treasure Chests Available: 8

With Ereshan possessing the knowledge to both activate and deactivate Aten, Zero urged the Seer to return to the current timeline and prevent the impending doom of the Library.

Best Characters for Chapter 3

Most Characters Can Clear Chapter 3

Best Characters for This Chapter
Shamash Icon - Black Beacon Shamash Zero Icon - Black Beacon Zero Hephae Icon - Black Beacon Hephae Viola Icon - Black Beacon Viola
Ninsar Icon - Black Beacon Ninsar Ming Icon - Black Beacon Ming Logos Icon - Black Beacon Logos Nanna Icon - Black Beacon Nanna

Chapter 3 welcomes back Zero and her group to the current timeline to stop Ereshan's plan. The anomalies in this chapter are not particularly difficult to handle, especially if your characters are leveled up.

However, we recommend taking advantage of your enemies' elemental weaknesses to make short work of them. As such, prioritize using Light and Fire characters.

Chapter 3-1 Guide

Overview

The End of the Light
Light determines the optimal path even before embarking on its journey, as it is aware of its ultimate destination.

As Ereshan falls through the hole in the Library, she remembers Cosmos' mysterious message to her. Gravity suddenly reverses as she accepts her imminent death.

Meanwhile, Nanna and Shamash are searching for ways to uncover Aten's activation code. Having exhausted all possible options, Nanna stares at Cosmos' gift. Perhaps it will come in handy once the prophesied event begins to unfold.

Chapter 3-2 Guide

Overview

Paradoxical Spiral
Because we knew that Aten was about to explode, we set out on this journey to find the words of God in order to prevent this explosion. However, it is precisely because we have found the words of God that Aten is about to explode in the first place.
