The Unending Nightmare Atlas Passive Keystone modifies the behavior of Delirium in your maps, making it easier to deal with but significantly less rewarding.
The new Unending Nightmare Atlas Passive Keystone prevents Delirium fog from dissipating so you're no longer on a timer. But Delirium Orb and Simulacrum Splinters no longer drop, making it less rewarding. If you use this keystone, Delirium still adds monsters, and Reward Tiles based on your completion but it also still adds difficulty by making monsters in your map tankier. Because the fog doesn't dissipate, it may be impossible to remove Delirium when using this keystone, but you should be able to run Delirium more easily on sub-optimal map layouts.
If you're playing Softcore trade the application of this Keystone is pretty limited but it may be helpful for farming Large Cluster Jewels or adding Delirium to a sub-optimal map layout like Defiled Cathedral Map.
