Path of Exile 2: Delirium Guide – Fog Mechanics, Passives, & Rewards

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

Path of Exile 2 features four primary endgame map events: Rituals, Breaches, Expeditions, and Delirium. Delirium, a returning mechanic from previous PoE leagues, presents a unique challenge and rewarding experience. This guide details how to initiate and master Delirium encounters, including the Simulacrum Pinnacle event, the Delirium Passive Skill Tree, and the valuable rewards.

Understanding the Delirium Fog Mechanic

Atlas map nodes offering guaranteed Delirium events are marked with a distinctive white and black icon resembling the Delirium Mirror. Alternatively, place a Delirium Precursor Tablet in a Lost Tower to guarantee a Delirium event on that node.

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

Enemies within the fog are significantly stronger but offer unique rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Fractured Mirrors, found within the fog, trigger additional waves of enemies and increased loot.

Two potential bosses, Kosis and Omniphobia, may randomly appear during a Delirium encounter. These are full-fledged bosses, not Rare enemies, so be prepared. They can also appear within the Simulacrum event.

The Simulacrum Pinnacle Event

Each endgame event yields items to summon a Pinnacle Boss. In Delirium, high-tier Waystones yield Simulacrum Splinters. Accumulate 300 Splinters to create a Simulacrum, which is placed in the Realmgate on the Atlas Map.

The Simulacrum is a challenging 15-wave encounter with increasing difficulty. Delirium bosses have a higher chance of spawning in later waves. Completing the Simulacrum awards two Delirium Passive Skill points.

The 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's distinctly white and shaped like the Delirium Mirror icon.

The tree features eight Notable nodes and eight nodes increasing Simulacrum difficulty. Each Simulacrum completion grants two passive points. Increasing Simulacrum difficulty is necessary to reach new Notable nodes.

Notable Delirium Passive Nodes:

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 Event Rewards

Delirium Fog-affected enemies drop Distilled Emotions. Bosses also frequently drop them. These currencies anoint amulets with Notable Passive Skills, eliminating the need to allocate passive skill points.

Distilled Emotions also add guaranteed modifiers to Waystones, increasing Delirium debuff intensity. Simulacrum Splinters, also dropped by enemies, create the Simulacrum for the Pinnacle event, rewarding Delirium Passive points and a guaranteed unique item.

All PoE 2 Distilled Emotions:

Distilled Envy Distilled Fear Distilled Isolation

Mastering Delirium will significantly enhance your Path of Exile 2 endgame progress.
