Delirium league
Settlers Patch Notes
- The first 15 Waves have been removed from the Simulacrum. Usually, characters reaching this content were a high enough level that the first waves were tedious and unrewarding.
- We've also added more opportunities to obtain specific Unique Items, such as Voices, by defeating the Bosses as you complete Waves.
Necropolis Patch Notes
- Sources of Divination Cards drops from League content such as Legion, Blight, Delirium, Heist, Ritual, Expedition and Delve now instead drop Stacked Decks.
Affliction Patch Notes
- When Delirium fog has ceased its movement due to players engaging in other League content, walking out of the mist will no longer cause the Delirium fog to dissipate.
Ancestor Patch Notes
- The number of monster kills required to gain Delirium rewards in the following Maps has been increased in order to be more consistent with other Maps: Bramble Valley, Cold River, Crimson Township, Dry Sea, Forbidden Woods, Foundry, Frozen Cabins, Silo, and Stagnation.
Ultimatum Patch Notes
Delirium Changes
- Added and rebalanced various Cluster Jewel notables. Please read the Cluster Jewel Balance section for more information.
- The Quantity and Rarity bonus applied to monsters from Delirium encounters has been lowered as is now more consistent across Monster rarities. Previously, Monsters of Normal rarity had a disproportionately larger amount of Quantity and Rarity being applied to them compared to Monsters of higher rarities.
Harvest Patch Notes
Delirium Mechanics Added to the Core Game
- Delirium has been added to the core game. From the Torched Courts onwards, you'll have approximately a 5% chance to encounter a Mirror of Delirium in each area. Once you reach the Atlas, that chance will increase by a small amount for each other league, atlas or master mechanic that appears in that area. In other words, if your goal is to encounter Mirrors of Delirium then you are encouraged to use your Zana modifiers, master missions, sextants, and whatever else you have available to you!
- You'll now have a greater chance of finding Cluster Jewels through Delirium encounters, proportional to the number of rewards you earn during that encounter.
Introduction
The Delirium league and Hardcore Delirium league were playable challenge leagues. They launched on March 13, 2020 (UTC) or March 14 New Zealand local time, alongside the Version 3.10.0 patch.
In this league, each area contains a Mirror of Delirium. When players pass through the mirror, it creates a fog of Delirium that spawns new enemies and makes existing enemies tougher. The fog will continue to spread out, and the deeper players venture out, the stronger enemies get. Defeating enemies in the fog adds extra rewards, and enemies within the Delirium can drop Delirium orbs, which add a layer of Delirium to the entire map, and splinters that combine into a gateway to the Simulacrum. Enemies in the Delirium can also drop Cluster Jewels, which are socketed in the outermost sockets in the passive skill tree to create an entire cluster of passive skills and can be modified to grant different passive skills.
All characters and stashes were moved to Standard league and Hardcore league respectively when the leagues end. Characters that died in the Hardcore Delirium league were immediately moved to the permanent Standard league. The Mirror of Delirium can still appear randomly in the story maps and in Maps with the league modifier.
League mechanic
Encounter rate
Delirium Mirrors have a >8% chance to appear in a zone, from The Torched Courts in Act 5 onwards.
In Maps, Delirium Mirrors have a base 8% chance to appear in a zone.
Delirium Mirror
Randomly while players are completing the acts or running Maps, a Mirror of Delirium will spawn. They will always spawn within a close distance from the zone entrance.
Once a player passes through it, it spawns a gray mist that spreads outwards throughout the entire map, and the delirium encounter begins.
Encounter
New enemies and hazards can spawn within the mist and existing enemies can receive a Delirium modifier, making them stronger or giving them new attacks. All enemies in the mist are Delirious, giving them increased damage mitigation and damage. The further out you are in the mist, the stronger the effect.
Enemies in the mist can drop Cluster Jewel and 
Simulacrum Splinter (starting at maps).
As you kill enemies inside the mist, a reward bar on the bottom left will start filling up. Filling the bar will cause you to gain the reward type after the Delirium encounter, and can be filled multiple times. When the first bar reaches level 3, a second reward bar will appear, and at level 5 a third reward bar appears.
Timer
Delirium encounters only last a short period of time. After a certain period of time, the mist will stop spreading, and a countdown begins. If you step out of the mist for more than 5 seconds, the Delirium encounter will end. Any enemies outside the mist will have their Delirium modifiers removed. The encounter can also be prematurely ended by pressing a button on the bottom right (which can be key bound). Certain actions will pause or extend the time before the mist stops spreading. The mist also stops moving while there are no players in the instance.
The following will pause the mist timer:
- During an Immortal Syndicate Research encounter
- During an Incursion encounter
- During a Legion Timeless Monolith encounter
- During a Breach encounter
- Being within range of a Blight portal
- While in the Sacred Grove
- While within radius of a Ritual Altar
The following will extend the mist timer:
- Opening a Strongbox
- Defeating a monster holding an Essence
- Capturing a red Beast
- Defeating an Immortal Syndicate group
- An Abyss crack starts moving to the next direction
- Completing a Blight encounter
- Defeating a Metamorph
- Defeating a Harbinger
- Opening a Perandus chest
Delirium orbs
Delirium Orb can be applied to maps to cover the entire map in mist permanently. Each orb makes the map 20% more Delirious, and up to 5 orbs can be used in one map. Rewards will also drop each time the bar is filled, since the mist never clears up. Enemies at very high Delirious percents are extremely tough, with even normal rarity enemies becoming comparable to high tier map bosses.
Strange Voice
Starting from The Torched Courts (Act 5), a voice starts talking to the player whenever you touch a Mirror of Delirium. He has unique lines in Act zones.
