Path of Exile 2's Atlas Endgame: Mastering the Delirium Encounter
Path of Exile 2 (PoE 2) features four major endgame Atlas map events: Rituals, Breaches, Expeditions, and Delirium. This guide focuses on Delirium, a returning mechanic from previous PoE leagues, detailing its initiation, mechanics, rewards, and the Simulacrum Pinnacle event.
Understanding the Delirium Fog Mechanic
On the Atlas, Delirium-enabled map nodes are marked with a distinctive white and black icon resembling the Delirium Mirror. To guarantee a Delirium event, insert a Delirium Precursor Tablet into a Lost Tower.
Within a Delirium map, locate the multicolored, shattered-glass Delirium Mirror near your spawn. Activating it unleashes a swirling circle of Delirium Fog. This fog expands, increasing enemy difficulty. Leaving the fog ends the encounter and resets the map.
Enemies within the fog are enhanced and drop unique rewards: Distilled Emotions (used in crafting) and Simulacrum Splinters (for summoning the Pinnacle Boss). Fractured Mirrors within the fog spawn additional mobs and loot. Be wary of Kosis and Omniphobia, full-fledged bosses that may randomly appear.
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 15-wave Simulacrum event. Difficulty escalates with each wave, increasing the likelihood of encountering Delirium bosses. Completion grants 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 rewards two passive points, necessitating increased difficulty with each new Notable node.
Notable Delirium Passive Nodes:
| 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 fog 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 |
| I'm Not Afraid Of You! | Delirium Bosses have 50% increased Life, drop 50% more Splinters | You Can't Just Wake Up From This One |
| They're Coming To Get You... | Unique Bosses spawn 25% more often; slaying rares pauses fog dissipation | N/A |
| Isn't It Tempting? | 30% chance for an extra reward; Delirium Demons deal 30% increased damage | N/A |
| The Mirrors... The Mirrors! | Delirium Fog spawns Fractured Mirrors twice as often | N/A |
| It's Not Real, It's Not Real! | Delirium enemies drop 50% more reward progress; fog dissipates 50% faster | N/A |
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.
Delirium Rewards
Delirium enemies and bosses drop Distilled Emotions, used to Anoint amulets with Notable Passive Skills or add modifiers to Waystones.
Simulacrum Splinters, also dropped by enemies, combine to create the Simulacrum for the Pinnacle event, yielding Delirium Passive points and a guaranteed unique item.
