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

Path of Exile 2 (PoE 2) features four major endgame Atlas 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 event.

Understanding Delirium and the Fog Mechanic

Atlas map nodes offering guaranteed Delirium events 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 on the desired node.

Within a Delirium map, locate the multicolored, shattered-glass Delirium Mirror near your spawn. Activating it unleashes a swirling circle of Fog. This Fog expands, increasing enemy difficulty. 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, appearing throughout the map, offer additional mob waves and loot upon interaction. Be wary of Kosis and Omniphobia, full-fledged bosses that can randomly appear during the encounter (and potentially within the Simulacrum).

The Simulacrum Pinnacle Event

Each endgame event provides materials for summoning a Pinnacle Boss. Delirium Fog drops Simulacrum Splinters (at higher Waystone tiers). Accumulate 300 splinters to create a Simulacrum, placing it in the Realmgate to access a challenging 15-wave encounter. Difficulty escalates with each wave, increasing the likelihood of encountering Delirium bosses. Completing the Simulacrum awards two Delirium Passive Skill points.

The Delirium Passive Skill Tree

The Delirium Passive Skill Tree, found within the Atlas Passive Skill Tree (top-right section), modifies Delirium events. It features eight Notable nodes and eight nodes increasing Simulacrum difficulty. Each Simulacrum completion grants two passive points, necessitating increased difficulty with each new Notable node.

Notable Delirium Passive Nodes and Effects:

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 Fog-affected enemies drop Distilled Emotions. Bosses also frequently drop them. These currencies anoint amulets with Notable Passive Skills, eliminating the need to allocate passive skill points. They also add guaranteed modifiers to Waystones, increasing Delirium mob density and power. Simulacrum Splinters, used to create the Simulacrum, yield unique equipment upon Simulacrum completion.
