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 features four major endgame encounters: Rituals, Breaches, Expeditions, and Delirium. Delirium, a returning mechanic from previous leagues, offers a unique and challenging endgame experience. This guide details how to initiate Delirium events, navigate the mechanics, access the Simulacrum Pinnacle map, utilize the Delirium Passive Skill Tree, and maximize your rewards.

Understanding the Delirium Fog Mechanic

On the Atlas, map nodes guaranteeing Delirium are marked with a distinctive white and black icon resembling the Delirium Mirror. You can guarantee a Delirium event by placing a Delirium Precursor Tablet in 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, increasing enemy difficulty as it progresses. Leaving the fog ends the encounter and resets the map.

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

The Simulacrum Pinnacle Event

Each endgame event provides materials to summon a Pinnacle Boss. High-tier Waystones in Delirium drop Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, which you place in the Realmgate.

The Simulacrum is a 15-wave challenge with escalating difficulty. Delirium bosses have an increased chance of spawning in later waves. Completing the Simulacrum grants two Delirium Passive Skill points.

The Delirium Passive Skill Tree

The Delirium Passive Skill Tree, located within 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 rewards two passive points; you must increase Simulacrum difficulty to reach new Notable 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.

Delirium Rewards

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

Distilled Emotions also add guaranteed modifiers to Waystones, increasing the Delirious debuff and mob density within the fog. Simulacrum Splinters, also dropped by enemies, combine to create the Simulacrum, leading to a unique event with guaranteed unique equipment.
