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

Path of Exile 2: A Comprehensive Guide to Delirium Endgame Events

Path of Exile 2's Atlas map features four major endgame encounters: 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

On the Atlas, Delirium-enabled map nodes are marked with 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 point. Approaching it activates the encounter, generating a large circle of Fog. This Fog expands across the map, increasing enemy difficulty with its progression. Leaving the Fog ends the encounter and resets the map.

Enemies within the Fog are enhanced and may drop valuable rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Fractured Mirrors, found within the Fog, trigger additional mob waves and increased loot. Be wary of Kosis and Omniphobia, full-fledged bosses that can appear randomly during the encounter.

The Simulacrum Pinnacle Event

Each endgame event offers Pinnacle Boss summoning items. High-tier Waystones in Delirium 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 likelihood of encountering Delirium bosses. Completing the Simulacrum awards two Delirium Passive points.

The Delirium Passive Skill Tree

The Delirium Passive Skill Tree, accessible 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 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 Rewards

Delirium Fog-affected enemies drop Distilled Emotions. Bosses also frequently yield these unique currencies, used to Anoint amulets with Notable Passive Skills. They can also enhance Waystones with guaranteed Delirious debuffs. Simulacrum Splinters, dropped by enemies, combine to form a Simulacrum for the Pinnacle event, rewarding Delirium Passive points and a guaranteed Unique item.

All PoE 2 Distilled Emotions:

Distilled Ire Distilled Guilt Distilled Greed Distilled Paranoia Distilled Envy Distilled Disgust Distilled Despair Distilled Fear Distilled Suffering Distilled Isolation

Mastering the Delirium encounter requires strategic navigation of the Fog, efficient use of the passive skill tree, and understanding the valuable rewards it offers.
