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

Path of Exile 2's Atlas map features four major endgame encounters: 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

On the Atlas, map nodes guaranteeing Delirium are marked with a distinct white and black icon resembling the Delirium Mirror. You can ensure 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 moving circle of Fog. Enemies within the Fog are stronger, dropping unique rewards like Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Fractured Mirrors within the Fog spawn additional mobs and loot.

Two random bosses, Kosis and Omniphobia, may appear. These are full-fledged bosses, not Rare enemies. They can also appear during the Simulacrum Pinnacle event.

The Simulacrum Pinnacle Event

Each endgame event offers items for summoning a Pinnacle Boss. High-tier Waystones in Delirium yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, placing it in the Realmgate to access a challenging 15-wave encounter. Delirium bosses have an increased chance of spawning in later waves. Completion rewards two Delirium Passive points.

The Delirium Passive Skill Tree

Located within the Atlas Passive Skill Tree (top-right section), the Delirium Passive Skill Tree (distinctly white, mirror-shaped) 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:

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; Rare monster kills pause Fog dissipation.	N/A
Isn't It Tempting?	30% chance for an extra reward, but 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, but 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

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.

Distilled Emotions also add guaranteed Modifiers to Waystones, increasing Delirious debuff effects. Simulacrum Splinters, also dropped by enemies, combine to form a Simulacrum for the Pinnacle event, rewarding Delirium Passive points and a guaranteed Unique item.

All PoE 2 Distilled Emotions:

Distilled Ire Distilled Guilt Distilled Greed Distilled Paranoia Distilled Envy Distilled Disgust Distilled Despair Distilled Fear Distilled Suffering Distilled Isolation

Mastering the Delirium encounter requires understanding its mechanics, strategically utilizing the passive skill tree, and efficiently managing rewards. This guide provides the foundation for maximizing your experience and loot within this challenging endgame event.
