Path of Exile 2: A Comprehensive Guide to Delirium Endgame Events
Path of Exile 2 features four major endgame map events: Rituals, Breaches, Expeditions, and Delirium. Delirium, a returning mechanic from previous PoE leagues, offers a unique and challenging endgame experience. This guide details how to initiate Delirium events, navigate the mechanics, access the Simulacrum Pinnacle map, utilize the Delirium Passive Skill Tree, and maximize rewards.
Understanding the Delirium Fog Mechanic
Atlas map nodes offering guaranteed Delirium events are marked with a distinctive white and black icon resembling the Delirium Mirror. You can guarantee a Delirium event by placing a Delirium Precursor Tablet in a Lost Tower.
Within a Delirium map, locate the multi-colored, shattered-glass Delirium Mirror near your spawn point. Activating it unleashes a swirling circle of Delirium Fog. The Fog’s difficulty increases as you progress, and leaving the Fog ends the encounter.
Enemies within the Fog are significantly stronger but offer valuable 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 potential encounters with the bosses Kosis and Omniphobia, who possess full boss health pools.
The Simulacrum Pinnacle Event
High-tier Waystones yield Simulacrum Splinters. Accumulate 300 splinters to create a Simulacrum, which can be placed in the Realmgate on the Atlas.
The Simulacrum is 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.
Mastering the Delirium Passive Skill Tree
The Delirium Passive Skill Tree, located within the Atlas Passive Skill Tree, modifies Delirium events. It's easily identified by its white coloration and mirror shape. Eight Notable nodes offer significant benefits, while eight others increase Simulacrum difficulty. Each new Notable node requires completing a Simulacrum to unlock.
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.
| Notable Delirium Passive | Effect | Requirements |
|---|---|---|
| Get Out Of My Head! | 20% chance for Waystones to have an Instilled Emotion effect | N/A |
| Would You Like To See My Face? | Doubles difficulty scaling, doubles Splinter stack size | Get Out Of My Head! |
| You Can't Just Wake Up From This One | Delirium Fog dissipates 30% slower | N/A |

Reaping the Rewards: Distilled Emotions and More
Delirium Fog-affected enemies drop Distilled Emotions. These unique currencies anoint amulets with Notable Passive Skills, eliminating the need for skill point investment. They can also enhance Waystones with guaranteed modifiers. Simulacrum Splinters, also dropped by enemies, are combined to access the Simulacrum event, rewarding Delirium Passive points and a guaranteed Unique item.

By following these steps, you can effectively navigate the Delirium endgame in Path of Exile 2 and maximize your rewards.
