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

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

Path of Exile 2 (PoE 2) features four major endgame map events: Rituals, Breaches, Expeditions, and Delirium. This guide focuses on Delirium, a returning mechanic from previous PoE leagues, detailing how to initiate events, navigate the mechanics, utilize the passive skill tree, and maximize rewards.

Understanding the Delirium Fog Mechanic

On the Atlas, Delirium map nodes are marked with a distinctive white and black mirror icon. You can guarantee a Delirium event by placing a Delirium Precursor Tablet in a Lost Tower.

Within a Delirium map, locate the multicolored Delirium Mirror near your spawn. Activating it unleashes a swirling fog that expands across the map. Enemies within the fog are significantly stronger but yield superior rewards. Leaving the fog ends the encounter.

Enemies within the fog drop valuable items: Distilled Emotions (used in crafting) and Simulacrum Splinters (used to summon the Pinnacle Boss). Fractured Mirrors, appearing randomly, offer additional waves of enemies and loot. Be wary of Kosis and Omniphobia, full-fledged bosses that can randomly appear during the event.

The Simulacrum Pinnacle Event

High-tier Waystones yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, placing it in the Realmgate to access the Simulacrum event – a challenging 15-wave encounter. Delirium bosses have an increased chance of appearing in later waves. Completion rewards two Delirium Passive Skill points.

The Delirium Passive Skill Tree

Accessible via the Atlas Passive Skill Tree (top-left button on the Atlas Map, then top-right), the Delirium Passive Skill Tree offers modifiers to enhance rewards or add complexity. It's visually distinct, shaped like the Delirium mirror.

Eight Notable nodes and eight difficulty-increasing nodes exist. Each Simulacrum completion grants two passive points, necessitating increased difficulty with each new Notable node.

Prioritize these Notable nodes: "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 Rewards

Delirium-affected enemies drop Distilled Emotions. These currencies anoint amulets with Notable Passive Skills, eliminating the need for passive skill point investment. They can also modify Waystones, adding a Delirious debuff.

Simulacrum Splinters, also dropped by enemies, combine to form a Simulacrum for the Pinnacle event. Completing the Simulacrum guarantees a unique item.

Mastering the Delirium encounter is crucial for maximizing your endgame progression in PoE 2. By understanding the mechanics, strategically utilizing the passive skill tree, and efficiently collecting rewards, you can significantly enhance your character's power and capabilities.
