Complete Guide to Delirium and Simulacrum Farming in Path of Exile 2: How to Get Rewards and Defeat Bosses

Delirium Farming Guide

This Farming Guide covers the basics of farming Delirium in Path of Exile 2, its rewards, and how to challenge the pinnacle encounter, the Simulacrum. Additionally, it includes the best Atlas Passive Nodes to take for optimized currency generation.

How it Works

While completing Waystones on your Atlas, you will encounter maps with the Delirium mechanic. To start the encounter, walk through the Mirror at the beginning of the map. Touching the Mirror causes a grey mist to spread across the map in a large circle, which slowly moves forward.

This mist summons special Delirium monsters and increases the defensive power of all monsters, the further they are from the Mirror. Move near Fractured Mirrors scattered throughout the Delirium area to release additional packs of monsters. However, make sure not to fall too far behind, as the fog will eventually fade behind you. Staying outside the mist for longer than 4 seconds will end the encounter.

Be cautious, as every Delirium Encounter has a chance to spawn one of the two unique Bosses: Kosis and Omniphobia.

The Rewards

Killing monsters affected by the fog fills up your reward bar, which is shown above your flasks. Delirium-specific mobs fill the bar faster and can drop Simulacrum Splinters (Requires Tier 11+ Waystones). The number displayed indicates how many Distilled Emotions will drop once the encounter ends. You can end the encounter early by clicking the UI button above your Skillbar.

Exclusive Delirium Rewards include:

• Distilled Despair
• Distilled Disgust
• Distilled Envy
• Distilled Fear
• Distilled Greed
• Distilled Guilt
• Distilled Ire
• Distilled Isolation
• Distilled Paranoia
• Distilled Suffering

Simulacrum Splinters also drop in Waystone tiers 11 and above.

How to Run

"Look for a map with the Delirium Mirror icon to find Delirium encounters!"

Maps have a chance to naturally contain a Delirium Mirror, as indicated by the icon shown above.

To guarantee the Delirium encounter on your Waystones, use a Delirium Precursor Tablet on a Watchtower. This will add a Delirium encounter to the number of Waystones specified in the implicit modifier of the item. Any explicit modifiers will apply to all uncompleted maps within the tower's radius.

Alternatively, you can Instill your Waystones to add inherent layers of Delirium. Learn how to Instill Waystones in the Distilled Emotions section. Keep in mind, this does not stack with Delirium Mirrors, so choose one of the two options.

Pinnacle Encounter: Simulacrum

Simulacrum

Delirium, like all of the Atlas Mechanics in Path of Exile 2's early access, features a Pinnacle Boss encounter. After gathering 300 Simulacrum Splinters and combining them, you will receive a Simulacrum. Place this into the Realmgate at the center of your Atlas (near your Atlas starting location) to open a portal to the Simulacrum.

To complete the encounter, you must fight through 15 waves of monsters that progressively become more difficult. Each wave has a selection of randomized negative mods (e.g., "Monsters Penetrate 25% of Elemental Resistances"), which are similar to map mods. After completing a wave, you are awarded Delirium-specific items, and defeating all 15 waves grants you 2 Atlas Passive Points for the Delirium mechanic. You can raise the difficulty of the encounter to earn additional points upon completion. Be careful: Wave 15 is extremely difficult.

The difficulty starts off easy but increases significantly as you progress through the waves. Kosis is the most difficult boss that can spawn during the Simulacrum, and his spawn rate increases the closer you get to Wave 15. Kosis has a unique loot table, which is shown in the Loot Breakdown below. Omniphobia is another boss that can spawn but does not have its own loot table.

Kosis’ lethal abilities are well telegraphed and intuitive to avoid. One ability to particularly watch out for is his beam that he channels from his belly, which can be deadly if not avoided. Omniphobia tries to close the distance to hit you with melee attacks but is otherwise straightforward. Dodge these attacks or keep your distance if your build allows it.

Distilled Emotions

Right-click any Distilled Emotion to open the Instilling UI. Here, you can enhance the effects of your Waystones or add a permanent Passive Notable to your Amulet, depending on the combination of Emotions you use.

"Add Extra Modifiers to your Waystones"

Tip: Three Distilled Paranoias add 36% more Rare monsters to your maps, which are responsible for the majority of Currency drops!

"Add a Passive Notable to your Amulet"

Tip: Hold your Extended Item Description Key when hovering over a desired Notable on your Passive Skill Tree to see the Emotions required for Instilling.

3 Distilled Emotions of the same name can be upgraded to the next tier with the Reforging Bench.
