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 tier, similar to a Delirium Orb map. 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 or from killing delirious monsters.

Notably, Delirium rewards will almost always drop at least one Cluster Jewel upon reaching a new reward tier, making it useful especially in SSF.

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 Eternity and Descent Into Madness.
