Just Fight when You are with Shania

Follow Shania

If you move away from Shania, Shania will stay where she is. Shania will not follow up if you try to run away from battles when targeted by an enemy, so it is better to just defeat the enemy you encounter when you are with her.

Travel by Skip Travel is Recommended

In the quest "Castle Access", you have to go back and forth to the destination over and over again. It is more efficient to use Skip Travel to get from a nearby landmark to a destination than to travel on foot.

To access the shoals where the ring is, you have to jump from the rope as shown in the video. You might have to do it over and over again since it is difficult to land on the position you aimed due to inertia. If you fail, use Skip Travel to start over from the landmark nearby.

Hints of Battle Against Moebius M

Watch Out the Bind Debuff

Watch Out the Bind Debuff

Mobius M's "Dominion Flower" has a bind effect that disables traget's moves for a certain time. You can get out of the bind state faster by shaking the left stick rapidly and hitting the right button repeatedly.

Your Allies Might Defect to Mobius M


The "Eclipse Soul" activated by Mobius M will cause your member to temporarily take Mobius M's side and begin attacking the allies. The manipulated character is unalbe to use and the paired Interlink will also not work.
