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

Path of Exile 2 (PoE 2) offers four primary endgame Atlas map encounters: Rituals, Breaches, Expeditions, and Delirium. This guide focuses on Delirium, a returning mechanic from previous PoE leagues, detailing its initiation, mechanics, rewards, and the associated Simulacrum Pinnacle event.

Understanding the Delirium Fog Mechanic

Atlas map nodes with guaranteed endgame events are marked with specific icons. A Delirium Mirror node 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 spawn point. Activating it unleashes a swirling circle of Delirium 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 enhanced and may drop valuable rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Encountering Fractured Mirrors spawns additional mobs and loot. Be wary of Kosis and Omniphobia, full-fledged bosses that can randomly appear.

The Simulacrum Pinnacle Event

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

Navigating 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. It features eight Notable nodes and eight nodes increasing Simulacrum difficulty. Each Simulacrum completion grants two passive points; increased Simulacrum difficulty is necessary to access new Notable nodes.

Notable Delirium Passive Nodes: 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, eliminating the need for passive skill point investment.

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.
