Delirium league

"A mysterious affliction has infiltrated your mind. As you touch the Mirror of Delirium, reality turns to mist and your worst nightmares emerge before your eyes. As the mists of Delirium consume you, new enemies emerge and existing foes gain savage talents. Delirium introduces dozens of lethal monster modifiers, many new bosses, and horrifying demons lurking within rare and unique monsters.

As you travel deeper into the Delirium, you'll experience more numerous and challenging enemies with greater rewards. Will you let greed and hubris draw you into the madness ?"

- Description on the official Path of Exile website

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. 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.
