Path of Exile 2's Atlas Endgame: A Comprehensive Guide to Delirium

Path of Exile 2 (PoE 2) features four major endgame events within the Atlas map: Rituals, Breaches, Expeditions, and Delirium. This guide focuses on Delirium, a returning mechanic from previous PoE Leagues, detailing how to initiate events, navigate the encounter, utilize the passive skill tree, and maximize rewards.

Understanding the Delirium Fog Mechanic

Delirium Mirror Icon

On the Atlas, Delirium map nodes are identified by a distinctive white and black icon resembling the Delirium Mirror. To guarantee a Delirium event, insert a Delirium Precursor Tablet into a Lost Tower.

Within a Delirium map, locate the multicolored, shattered-glass Delirium Mirror near your spawn. Activating it unleashes a swirling circle of Fog. This Fog expands, increasing enemy difficulty. Leaving the Fog ends the encounter and resets the map.

Enemies within the Fog are enhanced and drop unique rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Fractured Mirrors, if encountered, spawn additional mobs and loot upon interaction.

Random boss encounters with Kosis and Omniphobia may occur during a Delirium event; these are full-fledged bosses, not just rare enemies. They can also appear within the Simulacrum Pinnacle event.

The Delirium Pinnacle Event: Simulacrum

Every endgame event offers Pinnacle Boss summoning items. High-tier Waystones within Delirium Fog yield Simulacrum Splinters. Accumulate 300 Splinters to create a Simulacrum, placing it in the Realmgate to access the 15-wave Simulacrum event. Difficulty escalates with each wave, increasing the chance of encountering Delirium bosses. Completion rewards two Delirium Passive points.

Navigating the Delirium Passive Skill Tree

Delirium Passive Skill Tree

The Delirium Passive Skill Tree, accessed via the Atlas Passive Skill Tree (top-left button on the Atlas Map, then top-right), modifies Delirium events. It features eight Notable nodes and eight nodes increasing Simulacrum difficulty. Each Simulacrum completion grants two passive points, necessitating increased difficulty for new Notable nodes.

Notable Delirium Passive Effect Requirements
Get Out Of My Head! 20% chance for Waystones to have an Instilled Emotion effect N/A
Would You Like To See My Face? Doubles difficulty scaling and Splinter stack size Get Out Of My Head!

Prioritize "You Can't Just Wake Up From This One," "Get Out Of My Head!," and "They're Coming To Get You" for optimal reward increases without significant drawbacks.

Delirium Rewards

Distilled Emotions

Delirium Fog-affected enemies drop Distilled Emotions. Bosses also frequently yield these. These Currencies anoint amulets with Notable Passive Skills, eliminating the need for passive point investment. They can also enhance Waystones with guaranteed Delirious debuffs.

Simulacrum Splinters, also dropped by enemies, combine to form Simulacrums for the 15-wave event. Completion grants Delirium Passive points and a guaranteed unique item.
