Path of Exile 2's Endgame: A Deep Dive into Delirium

Path of Exile 2 introduces four major endgame map events: Rituals, Breaches, Expeditions, and Delirium. This guide focuses on Delirium, a returning mechanic from previous PoE leagues, detailing how to initiate events, understand the mechanics, access the Simulacrum Pinnacle map, utilize the Delirium Passive Skill Tree, and maximize rewards.

Understanding the Delirium Fog Mechanic

Delirium Mirror Icon

On the Atlas, Delirium map nodes 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 Delirium Mirror near your spawn. Activating it unleashes a spreading circle of Fog. The Fog's difficulty increases as it expands; leaving the Fog ends the encounter. Enemies within the Fog are enhanced and drop unique rewards:

Distilled Emotions: Used for crafting and anointing.
Simulacrum Splinters: Used to summon the Pinnacle Boss.
Fractured Mirrors: Interacting with these spawns additional mobs and loot.

Two random bosses, Kosis and Omniphobia, may appear during a Delirium encounter. These are full bosses, not rare enemies.

The Simulacrum Pinnacle Event

High-tier Waystones within Delirium yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, placing it in the Realmgate to access the 15-wave Simulacrum event. Difficulty escalates with each wave, increasing the chance of encountering Kosis and Omniphobia. Completion rewards two Delirium Passive Skill points and a guaranteed unique item.

The Delirium Passive Skill Tree

Delirium Passive Skill Tree

Located within the Atlas Passive Skill Tree (top-right), the Delirium Passive Skill Tree (distinguished by its white coloration) modifies Delirium events. It features eight Notable nodes and eight nodes increasing Simulacrum difficulty. Each new Notable node requires increasing the Simulacrum's difficulty.

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, 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, 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
Isn't It Tempting?	30% chance for an extra reward, Delirium Demons deal 30% increased damage	N/A
The Mirrors... The Mirrors!	Delirium Fog spawns Fractured Mirrors twice as often	N/A
It's Not Real, It's Not Real!	Delirium enemies drop 50% more reward progress, Fog dissipates 50% faster	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 Fog-affected enemies drop Distilled Emotions. Bosses also frequently drop them. These currencies anoint amulets with Notable Passive Skills, eliminating the need for passive skill point investment. They also add guaranteed modifiers to Waystones, increasing Delirium mob density and power.

Simulacrum Splinters, also dropped by enemies, combine to create the Simulacrum for the Pinnacle event, rewarding Delirium Passive points and a unique item.
