Summary
Delirium farming has emerged as one of the most lucrative endgame currency strategies in Path of Exile 2, particularly after the patch 0.1.1 changes that increased monster density and improved the player-friendliness of Delirium encounters. This guide breaks down a high-investment strategy that yielded an average of 580 Simulacrum Splinters per map during a 15-map test—translating to approximately 90 Divine Orbs in Simulacrum value alone.

Understanding the Core Mechanic
Before diving into the setup, it's essential to understand what makes this strategy work. Simulacrum Splinters drop from monsters affected by Delirium fog in Tier 11+ maps. Collecting 300 Splinters combines into a Simulacrum, which grants access to the pinnacle Delirium encounter—a 15-wave gauntlet with significant rewards.
The key to this strategy is pushing maps to 200% Delirious status, the maximum intensity level. At this threshold, enemies become extremely dangerous (comparable to pinnacle bosses), but reward quality increases substantially across all fog-affected maps. Higher Delirious values produce increased loot drops and greater chances for valuable Delirium-exclusive rewards.
Required Setup and Investment
Atlas Preparation
The foundation of this strategy begins with the Atlas. You need to locate a city biome on your Atlas—these are most commonly found at Citadels. The city biome is crucial because it provides the optimal layout for maximizing splinter drops.
Getting Started:
Run random maps until you find a city biome on your Atlas
Run maps with Delirium Precursor Tablets to spawn a Grand Mirror
Complete the Grand Mirror map, kill the boss, and click the Grand Mirror
Select the city biome area on your Atlas to spawn Delirium fog there
Run several maps in that area to progress Delirious from 0% to 200%
The Delirium fog spreads across connected maps, and completing maps within the affected region increases the Delirious value across all affected maps until it reaches the maximum of 200%.
Delirium Precursor Tablets
Tablets are the most critical investment for this strategy. You'll need four Delirium Precursor Tablets with specific modifiers:
Mandatory Modifiers:
Delirium Fog spawns increased Fracturing Mirrors (5-10% increased)
Increased Stack Size of Simulacrum Splinters found in your Maps (5-10%)
Fracturing Mirrors are crucial because they release additional Delirium monsters as you approach them—more monsters mean more splinter drops. The stack size modifier directly multiplies your splinter gains.
Optional (but valuable):
Slaying Rare Monsters pauses the Delirium Mirror Timer for 2 seconds
Delirium Encounters are more likely to spawn Unique Bosses
Delirium Monsters have increased Pack Size
Cost Consideration: During testing, tablets with both mandatory modifiers cost approximately 5 Divine Orbs each. Tablets with an additional "increased number of rare monsters" modifier can cost 20+ Divine Orbs, but you can replicate some of that benefit through map crafting instead.
Map Selection and Crafting
Since you're using the expensive tablets with the two mandatory modifiers (saving 15 Divine per tablet by skipping the rare monster mod), you need to compensate by maximizing monster rarity on your waystones.
Budget-Friendly Approach:
Bulk craft a large number of maps
Exalt them all out to full modifiers
Corrupt them all
Use regex filtering to find maps with at least 50-60% monster rarity
Min-Max Approach (Higher Investment)
Start with a 5-modded map (you need 5 modifiers for this method to work)
Activate Omens of Chaotic Gravity, Chaotic Quantity, and Chaotic Effectiveness simultaneously
Use Chaos Warp to re-roll the map modifiers
This can yield maps with 100%+ monster rarity
Add a final Exalt for more item rarity
Corrupt the map (required for the Jado Atlas Master bonus)
Atlas Master: Jado
For this strategy, you'll want to select Jado as your Atlas Master. Jado provides bonuses that directly benefit this farming method:
Corrupted Waystones have one additional modifier
Double effectiveness for certain Precursor Tablet effects
Additional exceptional item drops
The key Jado nodes for this strategy are:
Corrupted Waystones have one additional modifier
Eastern Knowledge: Unforeseen Threats
Partial Translations: More effect of suffix modifiers on tablets
The suffix modifiers on your Delirium Tablets (increased Fracturing Mirrors and increased Splinter stack size) receive additional effectiveness from Jado's bonuses, generating even more splinters per map.
Delirium Atlas Passive Tree
While the general Atlas tree should be optimized for your build, specific Delirium nodes are essential:
Top Priority Nodes:
Would you like to see my face? : Doubles Simulacrum Splinter droprate (increases difficulty)
The mirrors… the mirrors! : Adds more Fracturing Mirrors for extra packsize
They're coming to get you… : More Unique Boss spawns and pauses timer when killing Rares
Additional Useful Nodes:
I'm not afraid of you! : Bosses are tankier but grant more splinters
Isn't it tempting? : More Rewards but more lethal Delirium mobs
