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 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 offering guaranteed Delirium events are marked with a distinctive white and black icon resembling the Delirium Mirror. Alternatively, place a Delirium Precursor Tablet in a Lost Tower to guarantee a Delirium event on that node.

Within a Delirium map, locate the multicolored, shattered-glass Delirium Mirror near your spawn. Approaching it triggers a ghostly energy effect. Entering the mirror initiates the encounter, encircling you with a moving ring of Delirium Fog.

The Fog's difficulty increases as you progress. Leaving the Fog ends the encounter and resets the map. Enemies within the Fog are enhanced and may drop valuable rewards: 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, can appear during a Delirium encounter. These are full-fledged bosses, not Rare enemies, so be prepared. They can also appear in the Simulacrum Pinnacle event.

The Delirium Pinnacle Event: Simulacrum

Each endgame event offers items to summon a Pinnacle Boss. In Delirium, high-tier Waystones yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum for the Realmgate.

Activating the Simulacrum initiates a 15-wave encounter of increasing difficulty. Delirium bosses have a higher chance of spawning in later waves. Completing the Simulacrum awards two Delirium Passive Skill points.

The Delirium Passive Skill Tree

The Delirium Passive Skill Tree, accessible via the Atlas Passive Skill Tree (top-left button on the Atlas Map, then top-right), modifies Delirium events. It's distinctly white and mirror-shaped. Eight Notable nodes and eight Simulacrum difficulty-increasing nodes exist.

Each Simulacrum completion grants two passive points, requiring increased difficulty for each new Notable node.

Notable Delirium Passive 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? Fog doubles difficulty scaling and Splinter stack size. Get Out Of My Head!
You Can't Just Wake Up From This One Fog dissipates 30% slower. N/A
I'm Not Afraid Of You! 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; Delirium Demons deal 30% increased Damage. N/A
The Mirrors... The Mirrors! Fog spawns Fractured Mirrors twice as often. N/A
It's Not Real, It's Not Real! 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 Event Rewards

Delirium Fog-affected enemies drop Distilled Emotions. Bosses also frequently drop them. These Currencies anoint Amulets with Notable Passive Skills, avoiding skill point investment.

Distilled Emotions also add guaranteed Modifiers to Waystones, increasing Delirious debuff and mob power. Simulacrum Splinters create the Simulacrum for the 15-wave event, rewarding 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
