How To Unlock Nocturnal Echoes Bosses In Duet Night Abyss

Eventually, both characters return to Camilla and bring a few Geniemon to show they are not dangerous. By the end of the quest, the Nocturnal Echoes feature is unlocked. To access these special bosses, open the Main Menu and enter Combat. In one of the tabs, Phoxhunters can find the Nocturnal Echoes option.
