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

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

Path of Exile 2 introduces four major 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 associated Simulacrum Pinnacle event.

Understanding the Delirium Fog Mechanic

On the Atlas, Delirium 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. Activating it unleashes a circular fog that expands across the map. Enemy difficulty increases with the fog's expansion; leaving the fog ends the event.

Enemies within the fog are enhanced and may drop valuable rewards:

• Distilled Emotions: Used in crafting.
• Simulacrum Splinters: Used to summon the Simulacrum Pinnacle Boss.
• Fractured Mirrors: Interacting with these spawns additional mobs and loot.

Random boss encounters with Kosis and Omniphobia may occur during a Delirium event, separate from the Pinnacle boss.

The Simulacrum Pinnacle Event

High-tier Waystones yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, placing it in the Realmgate to initiate a 15-wave challenge. Difficulty escalates with each wave, increasing the likelihood of encountering Delirium bosses. Completion rewards two Delirium Passive Skill points.

The Delirium Passive Skill Tree

Located within the Atlas Passive Skill Tree (top-right), the Delirium Passive Skill Tree (distinguished by its white color and mirror shape) offers modifiers to enhance rewards or add complexity. Eight Notable nodes and eight difficulty-increasing Simulacrum nodes exist. Each new Notable node requires increasing Simulacrum difficulty.

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 enemies and bosses drop Distilled Emotions, used for Amulet Anointing with Notable Passive Skills or adding guaranteed modifiers to Waystones.

Simulacrum Splinters, obtained from enemies, combine to create a Simulacrum for the Pinnacle event, rewarding Delirium Passive points and a guaranteed unique item.
