How to Get the New Morphed Deviations in Once Human: Isles of Abyss

Once Human's Isles of Abyss expansion adds several new Morphed Deviations plus an entirely new Deviation called Duet. Duet drops from The Sunken Lord boss fight, which is only available during the scenario's second phase, lasting around 11 days. Morphed Deviations appear only during seasonal events or major updates and function like regular Deviations, providing combat, crafting, and exploration benefits.
