Path of Exile 2's Atlas Endgame: Mastering the Delirium Encounter

Path of Exile 2 introduces four major endgame map events: Rituals, Breaches, Expeditions, and Delirium. Delirium, a returning mechanic from previous PoE leagues, offers a challenging and rewarding endgame experience. This guide details how to initiate Delirium events, navigate the Fog mechanic, 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 offering guaranteed endgame events are clearly marked. Delirium Mirror nodes display a distinctive black and white icon. 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 swirling 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 significantly stronger but offer unique Delirium 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 the randomly appearing bosses, Kosis and Omniphobia—they are challenging encounters with full boss health bars.

The Simulacrum Pinnacle Event

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

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

Navigating the Delirium Passive Skill Tree

The Delirium Passive Skill Tree, located on the Atlas Passive Skill Tree (top-left button, then top-right), modifies the Delirium experience. It features eight Notable nodes and eight nodes impacting Simulacrum difficulty. Each Simulacrum completion grants two 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.

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 spend passive skill points.

Distilled Emotions also add guaranteed modifiers to Waystones, increasing mob density and power within the Delirium Fog. Simulacrum Splinters, dropped by enemies, combine to create the Simulacrum for the Pinnacle event, rewarding Delirium Passive points and a unique item.
