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

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

Path of Exile 2's Atlas map features four major endgame encounters: Rituals, Breaches, Expeditions, and Delirium. Delirium, a returning mechanic from previous Path of Exile leagues, offers a unique and challenging endgame experience. This guide covers initiating Delirium events, understanding the mechanics, accessing the Simulacrum Pinnacle map, utilizing the Delirium Passive Skill Tree, and maximizing rewards.

Understanding the Delirium Fog Mechanic

On the Atlas, map nodes guaranteeing endgame events are marked with specific icons. A white and black icon resembling a mirror indicates a Delirium Mirror. You can guarantee Delirium events by placing a Delirium Precursor Tablet in a Lost Tower.

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

Enemies within the Fog are stronger and drop unique Delirium rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (used to summon the Pinnacle Boss). Fractured Mirrors within the Fog spawn additional waves of enemies and loot.

Random boss encounters with Kosis and Omniphobia can occur during a Delirium event. These are full bosses, not Rare enemies, so be prepared. They can also appear in the Simulacrum Pinnacle event.

The Simulacrum Pinnacle Event

Every endgame event provides items to summon a Pinnacle Boss. Delirium Fog drops Simulacrum Splinters, especially at higher Waystone tiers. Accumulate 300 Splinters to create a Simulacrum for the Realmgate.

Activating the Simulacrum initiates a 15-wave encounter of increasing difficulty. Delirium bosses have a higher chance of appearing in later waves. Completion rewards 2 Delirium Passive 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 on the top-right of the Atlas tree, easily identifiable by its white color and mirror shape.

The tree features eight Notable nodes and eight nodes increasing Simulacrum difficulty. Each Simulacrum completion grants 2 passive points, necessitating increased difficulty with each new Notable node.

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 rewards without significant drawbacks.

Maximizing Delirium Event Rewards

Delirium Fog-affected enemies drop Distilled Emotions. Bosses also frequently drop them. These currencies anoint Amulets with Notable Passive Skills, avoiding passive point investment.

Distilled Emotions also add guaranteed Modifiers to Waystones, increasing Delirious debuff and mob strength. Simulacrum Splinters, also dropped by enemies, combine to create a Simulacrum for the Realmgate, leading to a 15-wave Simulacrum event with guaranteed Unique equipment and Delirium Passive points.
