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

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

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 encounter. This guide details how to initiate Delirium events, navigate the Fog mechanic, access the Simulacrum Pinnacle map, utilize the Delirium Passive Skill Tree, and maximize your rewards.

Understanding the Delirium Fog Mechanic

Atlas Map Node with Delirium Mirror Icon

On the Atlas, Delirium events are indicated by a distinctive white and black icon resembling a mirror. To guarantee a Delirium event, place a Delirium Precursor Tablet in a Lost Tower.

Within a Delirium map, locate the multicolored Delirium Mirror near your starting point. Activating it unleashes a swirling Fog that expands across the map. Enemy difficulty increases with the Fog's expansion; exiting the Fog ends the event.

Enemies within the Fog are stronger but offer unique rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Fractured Mirrors, found within the Fog, trigger additional mob waves and loot. Be wary of the randomly spawning bosses, Kosis and Omniphobia – they're full-fledged bosses, not just Rare enemies.

The Simulacrum Pinnacle Event

Each endgame event provides materials for summoning a Pinnacle Boss. In Delirium, high-tier Waystones yield Simulacrum Splinters. Accumulate 300 Splinters to create a Simulacrum for the Realmgate.

The Simulacrum is a 15-wave gauntlet, with increasing difficulty and a higher chance of encountering Delirium bosses in later waves. Completion grants 2 Delirium Passive points.

Navigating the Delirium Passive Skill Tree

Delirium Passive Skill Tree

The Delirium Passive Skill Tree, accessed via the Atlas Passive Skill Tree, modifies Delirium events. It features eight Notable nodes and eight nodes impacting Simulacrum difficulty. Each Simulacrum completion rewards 2 passive points, necessitating increased Simulacrum difficulty for each new Notable node.

Notable Delirium Passive Nodes:

Notable Delirium Passive Effect Requirements

Prioritize "You Can't Just Wake Up From This One," "Get Out Of My Head!", and "They're Coming To Get You" for optimal rewards without significant drawbacks.

Delirium Rewards: Distilled Emotions and More

Distilled Emotions

Delirium Fog-affected enemies drop Distilled Emotions. These are crucial for Anointing amulets with Notable Passive Skills and modifying Waystones.

All Distilled Emotions

Simulacrum Splinters, also dropped by enemies, are combined to create the Simulacrum, leading to a unique event with guaranteed Unique equipment.

Mastering the Delirium event requires understanding its mechanics, strategically utilizing the Passive Skill Tree, and efficiently managing your resources. With practice, you'll reap the substantial rewards this challenging endgame encounter offers.
