PoE2 Delirium: Fog Mechanics, Passives, and Rewards Revealed

Path of Exile 2's Endgame: A Deep Dive into Delirium Events

Path of Exile 2 (PoE 2) offers four primary endgame map events: Rituals, Breaches, Expeditions, and Delirium. This guide focuses on Delirium, a returning mechanic from previous PoE leagues, detailing its initiation, mechanics, rewards, and the crucial Simulacrum Pinnacle encounter.

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, place a Delirium Precursor Tablet in a Lost Tower.

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, increasing enemy difficulty as you progress. Exiting the fog ends the encounter and resets the map.

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

Two potential bosses, Kosis and Omniphobia, can appear randomly within the fog. These are full-fledged bosses, not merely rare enemies. While they aren't Pinnacle bosses, they can appear during the Simulacrum event.

Conquering the Simulacrum Pinnacle Event

Every endgame event provides materials for summoning a Pinnacle Boss. In Delirium, high-tier Waystones yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, which you then place in the Realmgate on the Atlas.

The Simulacrum is a challenging 15-wave encounter with escalating difficulty. The chance of encountering Delirium bosses increases with each wave. Completion rewards two Delirium Passive Skill points.

Mastering the Delirium Passive Skill Tree

The Delirium Passive Skill Tree, accessible via the Atlas Passive Skill Tree, modifies Delirium events. It's located in the top-right of the Atlas tree, easily identifiable by its white coloration and mirror shape. It features eight Notable nodes and eight nodes increasing Simulacrum difficulty.

Since Simulacrum completion grants two passive points, you must increase the Simulacrum's difficulty with each new Notable node.

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.

Reaping the Rewards of Delirium

Delirium Fog-affected enemies drop Distilled Emotions. Bosses also frequently drop them. These currencies anoint amulets with Notable Passive Skills, eliminating the need to spend passive points. They can also add guaranteed modifiers to Waystones.

Simulacrum Splinters, also dropped by enemies, combine to form a Simulacrum for the Pinnacle event. Completing the Simulacrum yields Delirium Passive points and a guaranteed unique item.
