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

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. Delirium, a returning mechanic from previous PoE leagues, is detailed here. This guide covers initiating Delirium events, understanding the mechanics, accessing the Simulacrum Pinnacle map, utilizing the Delirium Passive Skill Tree, and maximizing rewards.

Understanding Delirium and the Fog Mechanic

On the Atlas, map nodes guaranteeing endgame events are marked with specific icons. Nodes hosting a Delirium Mirror display a distinctive black and white icon. You can ensure Delirium events by placing a Delirium Precursor Tablet in a Lost Tower.

Within a Delirium map, locate the multicolored, shattered-glass Delirium Mirror near your spawn. Activating it unleashes a swirling Fog encompassing you. This Fog expands across the map, increasing enemy difficulty with its progression. Leaving the Fog ends the encounter, resetting the map.

Enemies within the Fog are enhanced, potentially dropping unique Delirium rewards such as Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Fractured Mirrors within the Fog, when activated, spawn additional mobs and loot. Be aware of the possibility of encountering Kosis and Omniphobia, full-fledged bosses with significant HP, that can appear randomly.

The Delirium Pinnacle Event: Simulacrum

Each endgame event offers items to summon a Pinnacle Boss. High-tier Waystones in Delirium Fog yield Simulacrum Splinters. Accumulate 300 Splinters to create a Simulacrum, placing it in the Realmgate.

This initiates the Simulacrum, a challenging 15-wave encounter with escalating difficulty. Delirium bosses have an increased 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, located within the Atlas Passive Skill Tree (top-left button on the Atlas Map, then top-right), modifies Delirium events. Its white, mirror-shaped design is distinctive. 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.

Prioritize "You Can't Just Wake Up From This One," "Get Out Of My Head!," and "They're Coming To Get You" for maximized rewards 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, eliminating the need for passive point investment.

Distilled Emotions also add guaranteed modifiers to Waystones, increasing Delirium mob density and power. Simulacrum Splinters, also dropped by enemies, combine to form a Simulacrum for the 15-wave event, rewarding passive points and a unique item.
