Path of Exile 2: Delirium Guide – Fog Mechanics, Passives, & Rewards

Path of Exile 2's Endgame: Mastering the Delirium Encounter

Path of Exile 2 (PoE 2) offers four major endgame map events: Rituals, Breaches, Expeditions, and Delirium. Delirium, a returning mechanic from previous PoE leagues, is a challenging and rewarding endgame activity. This guide details how to initiate Delirium events, navigate the Delirium Fog, access the Simulacrum Pinnacle map, utilize the Delirium Passive Skill Tree, and maximize your rewards.

Understanding the Delirium Fog Mechanic

Atlas map nodes with guaranteed endgame events are marked with specific icons. A Delirium Mirror is indicated by a black and white icon resembling the mirror itself. To guarantee a Delirium event, place a Delirium Precursor Tablet in a Lost Tower.

Within a Delirium map, locate the multicolored, shattered-glass Delirium Mirror near your starting point. Activating it unleashes a swirling circle of Delirium Fog. This fog expands, increasing enemy difficulty as you progress. Leaving the fog ends the event 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 within the fog spawn additional waves of enemies and loot. Be aware of the randomly appearing bosses, Kosis and Omniphobia – these are full-fledged bosses, not just rare enemies.

The Simulacrum Pinnacle Event

Each endgame event provides materials to summon a Pinnacle Boss. High-tier Waystones in Delirium yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, which you place in the Realmgate on the Atlas.

The Simulacrum is a 15-wave gauntlet, escalating in difficulty. Delirium bosses have an increased chance of appearing in later waves. Completing the Simulacrum awards two Delirium Passive Skill points.

Navigating the Delirium Passive Skill Tree

The Delirium Passive Skill Tree, accessed via the Atlas Passive Skill Tree (top-left button on the Atlas Map, then top-right), modifies Delirium events. It's easily identified by its white coloration and mirror shape.

The tree features eight Notable nodes and eight nodes increasing Simulacrum difficulty. Since Simulacrum completion grants passive points, you must increase difficulty to access new Notable nodes.

Notable Delirium Passive Nodes: Strategic Choices

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 and More

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 points.

Distilled Emotions also add guaranteed modifiers to Waystones, increasing the Delirious debuff and mob density. Simulacrum Splinters, also dropped by enemies, combine to create the Simulacrum for the Pinnacle event, rewarding Delirium Passive points and a guaranteed unique item.
