24. Avoid Interlinking Against Moebius M

Approaching the objective marker at the west gate initiates a series of boss fights, so be prepared. When fighting against Moebius M, avoid Interlinking, especially if most of your allies are low on health, as the boss can take control of any of your characters, even during Ouroboros mode!

Try to fill the Chain Attack gauge and complete Ouroboros Orders instead to defeat Moebius M quickly.
