POE 2 Drop Rates - Simulacrum (Delirium Capstone Encounter)

POE 2 During in-map Delirium events in high level Waystones, you will be rewarded with Simulacrum Splinters. 300 of these combine to create a Simulacrum, which is used in the Realmgate on the Atlas.

The Simulacrum is a series of 15 combat encounters that take place in a replica of a POE2 town. Each will be harder than the last.

After each encounter you will receive a number of Distilled Emotions based upon the number and power of the monsters you killed.

Upon completing all 15, you will receive an additional unique item exclusive to the Simulacrum.

The Simulacrum allows you to opt in to additional difficulty after you have defeated it once, by allocating points on your Delirium atlas. These can raise the Difficulty to as high as 4. (Increases in Difficulty that would exceed 4 do not apply).

Higher Difficulty significantly increases monster power in the Simulacrum, but is required for some items to have a chance of dropping.

Distilled Emotion Drop Rates

It's not uncommon to get 60-90 Distilled Emotion drops from a full Simulacrum.

These are the current estimates for the relative drop rates.

Especially for Despair, Fear, Suffering and Isolation, these drop rates may not be overly accurate as they are based upon only a few thousand total emotion drops.

This table assumes you get 72 total Distilled Emotion drops across the 15 waves, which is not guaranteed. The faster you kill monsters, the more rewards you will earn, but there are sharp diminishing returns. 

Unique Item Overview

Assailum - This is the most common item from the Simulacrum at all difficulties.

Perfidy - This is second most common at all difficulties.

Melting Maelstrom - This is considered a chase item by players, as it is extremely powerful. It can drop on all difficulties.

Collapsing Horizon and Strugglescream - These items are known to be able to drop on Sifficulty 3 and 4, and suspected to be able to drop on Difficulty 2. Both are quite rare.

Megalomaniac - This item can only drop on Difficulty 4. It generates with either two or three modifiers, with the three modifier version being rarer and potentially stronger.

Drop rates are estimates based on runs compiled by the Discord community Prohibited Library.

Please note: The sample sizes are still somewhat small here, and a lot of this information is likely to become more accurate over time.

Drop Rates: Difficulty 0 and 1

For Difficulty 1, drop rates have been measured to be about

Assailum 65%

Perfidy 27%

Melting Maelstrom 8%

For most pinnacle bosses, the difference between Difficulty 0 and 1 is believed to be just an increased item rarity boost. Same uniques. It is not known whether the Simulacrum works that way.

On Difficulty 0, only small samples have been run. Their reported drop rates were similar enough to the Difficulty 1 rates that it is likely they are identical.

Drop Rates: Difficulty 2 and 3

Very few Difficulty 2 Simulacrums have been run.

At Difficulty 2 or 3, Collapsing Horizon and Strugglescream are added to the loot tables. 

Both of these items are quite rare.

Due to Melting Maelstrom and Megalomaniac being the most sought-after item in the Simulacrum, most players elect to run Difficulty 4 on very powerful characters and Difficulty 0 on less powerful ones, considering the addition of Collapsing Horizon to water down the loot tables overall. 

Drop Rates: Difficulty 4

At difficulty 4, two versions of Megalomaniac are added to the loot tables. One allocates two notables from the passive tree, the rarer, better version allocates three.

Megalomaniacs with two cohesive modifiers are extremely valuable. Megalomaniacs with one extremely powerful modifier (e.g. Endless Blizzard ) can also be valuable even if they have no other remotely useful modifiers.

Based upon a sample of 260 Simulacrums, it seems likely that some drops that would have been Assailum are instead replaced with Megalomaniac and/or other unique items.

Current estimates of drop rates:

Assailum 45%
Perfidy 24%
Melting Maelstrom 6.5%
Collapsing Horizon 10%
Strugglescream 6%
Megalomaniac (2 modifiers) 7.5%
Megalomaniac (3 modifiers) 1%
