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, explaining how to initiate and maximize your rewards.

Understanding the Delirium Fog Mechanic

Delirium Mirror Icon

Atlas map nodes with guaranteed Delirium events 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 point. Activating it unleashes a circular fog that expands across the map. Enemies within the fog are significantly stronger but yield superior rewards. Leaving the fog ends the encounter.

Enemies within the fog offer enhanced drops, including Distilled Emotions (used for crafting) and Simulacrum Splinters (used to summon the Pinnacle Boss). Fractured Mirrors, appearing randomly within the fog, trigger additional mob waves and loot opportunities. Be aware of potential boss encounters with Kosis and Omniphobia, who possess full boss health pools.

The Simulacrum Pinnacle Event

High-tier Waystones within Delirium maps drop Simulacrum Splinters. Accumulating 300 splinters allows you to craft a Simulacrum, which, when placed in the Realmgate, transports you to a challenging 15-wave event. The Simulacrum increases in difficulty with each wave, offering a higher chance of encountering Delirium bosses. Completing the Simulacrum awards two Delirium Passive Skill points.

Navigating the Delirium Passive Skill Tree

Delirium Passive Skill Tree

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

Notable Delirium Passive Nodes:

Notable Delirium Passive Effect Requirements
Get Out Of My Head! 20% chance for Waystones to have an Instilled Emotion effect. N/A
Would You Like To See My Face? Doubles fog difficulty scaling but also doubles Splinter stack size. Get Out Of My Head!
You Can't Just Wake Up From This One Delirium Fog dissipates 30% slower. N/A
I'm Not Afraid Of You! Delirium Bosses have 50% increased Life, but drop 50% more Splinters. You Can't Just Wake Up From This One
They're Coming To Get You... Unique Bosses spawn 25% more often; slaying rares pauses fog dissipation. N/A

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

Distilled Emotions

Delirium-affected enemies drop Distilled Emotions, also obtainable from bosses. These currencies anoint amulets with Notable Passive Skills, eliminating the need for passive skill point investment. They also enhance Waystones with guaranteed Delirious debuffs.

Simulacrum Splinters, dropped by enemies, combine to create the Simulacrum, leading to a unique event with guaranteed unique equipment.

All Distilled Emotions (Images of Distilled Ire, Guilt, Greed, Paranoia, Envy, Disgust, Despair, Fear, Suffering, and Isolation)

Mastering the Delirium encounter requires understanding its mechanics and strategically utilizing the passive skill tree to maximize your rewards.
