What if it's all just in your head?

Unending Nightmare is an Atlas passive skill and Atlas keystone, specifically for the Delirium league encounter.

Mechanics

Unending Nightmare causes Delirium fog from the Delirium Mirror to never dissipate in your maps, preventing it from being ended by any method, including by clicking the hotkey or button, meaning that the Delirium fog will add a permanent difficulty modifier to the map it spawns in. The player can claim the Delirium rewards upon its respective reward filling up, dropping on the floor as soon as a bar is filled up a level. Also, taking this notable disables the ability to find Simulacrum SplinterSimulacrum SplinterStack Size: 300Combine 300 Splinters to create a Simulacrum.s and Delirium Orbs as loot in your maps, either from claiming the Delirium rewards from the encounter itself, or from other loot sources.

Using this keystone nullifies the need to use The Singular Entity, but players can still choose to allocate The Singular Entity for a less intensive version of this keystone and still be able to acquire Simulacrum SplinterSimulacrum SplinterStack Size: 300Combine 300 Splinters to create a Simulacrum.s and Delirium Orbs from Delirium Mirror encounters and other sources.

Location

As of version 3.22.0, it is located near the center-left of the Atlas passive skill tree inside the Delirium cluster containing The Singular Entity and Descent Into Madness.
