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

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

Path of Exile 2 features four major endgame Atlas map events: Rituals, Breaches, Expeditions, and Delirium. Delirium, a returning mechanic from previous PoE leagues, offers a unique and challenging endgame experience. This guide details how to initiate and master Delirium encounters, including the Simulacrum Pinnacle boss fight, the Delirium Passive Skill Tree, and the valuable rewards it offers.

Understanding the Delirium Fog Mechanic

On the Atlas, map nodes with guaranteed endgame events are clearly marked. Delirium Mirrors are represented by a distinctive black and white icon. 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 spreading circle of Delirium Fog. The Fog's difficulty increases as it expands; leaving the Fog ends the encounter.

Enemies within the Fog are significantly stronger but drop unique rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (required for the Pinnacle boss). Fractured Mirrors, appearing randomly within the Fog, offer additional mob waves and loot. Be wary of Kosis and Omniphobia, full-fledged bosses that can appear randomly during the encounter (though not Pinnacle bosses themselves).

The Simulacrum Pinnacle Event

Completing Delirium events at higher Waystone tiers yields Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, which can be placed in the Realmgate. This initiates a challenging 15-wave Simulacrum encounter, with increasing difficulty and a higher chance of encountering Delirium bosses in later waves. Successfully completing the Simulacrum rewards two Delirium Passive Skill points.

Mastering the Delirium Passive Skill Tree

The Delirium Passive Skill Tree, found within the Atlas Passive Skill Tree (top-left button on the Atlas Map, then top-right), offers modifiers to enhance Delirium encounters. It features eight Notable nodes and eight nodes that increase Simulacrum difficulty. Each Simulacrum completion grants two points, necessitating increased difficulty to access 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 reward increases without significant drawbacks.

Valuable Delirium Rewards

Delirium enemies within the Fog drop Distilled Emotions. These unique currencies are used to Anoint amulets with Notable Passive Skills, bypassing the need for passive skill point investment. They can also enhance Waystones with guaranteed Delirious debuffs.

Simulacrum Splinters, also dropped by enemies, are combined to create the Simulacrum for the Pinnacle boss fight. Completing this fight rewards Delirium Passive points and a guaranteed unique item.

By understanding and utilizing these mechanics, players can effectively navigate the Delirium endgame and reap its substantial rewards.
