Path of Exile 2: A Comprehensive Guide to Delirium Endgame Events

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, navigate the encounter, utilize the 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 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 rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Fractured Mirrors, found within the Fog, trigger additional mob waves and increased loot. Be aware of Kosis and Omniphobia, powerful bosses that can randomly appear during the encounter (these are not Pinnacle bosses).

The Simulacrum Pinnacle Event

High-tier Waystones within Delirium maps yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, which you place in the Realmgate on the Atlas. This initiates a challenging 15-wave encounter with escalating difficulty. Delirium bosses have an increased chance of spawning in later waves. Completing the Simulacrum rewards two Delirium Passive Skill points.

Navigating the Delirium Passive Skill Tree

Delirium Passive Skill Tree

The Delirium Passive Skill Tree, located on 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 for each new Notable node.

Here's a selection of Notable nodes and their effects:

Notable Delirium Passive Effect Requirements
Get Out Of My Head! Waystones have a 20% chance to have an Instilled Emotion effect. N/A
Would You Like To See My Face? Doubles Fog difficulty scaling, but 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
Isn't It Tempting? 30% chance for an extra reward, but Delirium Demons deal 30% more 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, but Fog dissipates 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 Event 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 can also enhance Waystones with guaranteed modifiers.

Simulacrum Splinters, dropped by enemies, combine to create a Simulacrum for the Pinnacle event. Completing this event yields Delirium Passive points and a guaranteed unique item.
