PoE 2 0.5 Delirium Changes

New Storyline: An ancient Trickster God has been unleashed, spreading madness across Wraeclast. The entity of Delirium, the Strange Voice, has grown in power. A new progression system now measures how far you descend into the fog, with danger and madness intensifying as you venture deeper into the Withered Willow. Encounter warped reflections of reality alongside nightmarish foes. Those who endure will uncover potent new rewards, as well as deeper, more perilous layers of the Delirium.
There is now a hub area "The Withered Willow" for Delirium to the south-west of your starting location on the Atlas. The maps around this location all contain Deliriums, and give you points for the Delirium Atlas Passive Tree.
The Delirium Atlas Passive Tree has been completely revamped with many new nodes and existing nodes changed.
After breaking a Delirium mirror, there is now a progress bar showing how deep you are in the fog, and how long you have until the fog clears. The start of the Delirium bar represents your initial location at the Delirium mirror, the end of the Delirium bar represents the location of the map boss.
There are now a set of new Delirium Encounters that can be seen on the Delirium bar. Reaching certain depths will cause coloured mirror shards to appear. Walking into the mirror shards will break them, activating the new encounters.
The direction of the map boss can be observed by looking at the fog effect. Moving in the direction of the fog will always lead you to the map boss.
Map bosses in Delirium will always be 100% delirious.
The damage and life bonus given to monsters from Delirium has been reduced.
Added 5 new Elite Delirium Monsters
Added a new sub-area: Loathsome Mire.
The Loathsome Mire drops two new Amulet base types that grant two instilled notables at the cost of either -1 suffix or -1 prefix.
Liquid Emotions can now be used to craft additional mods on Jewels. These work similarly to greater essences, each having a set of specific mods that will replace a random existing mod on the item.
Completing Delirium Mirrors now has a chance to spawn Grand Mirrors on the Atlas on a nearby map. Grand mirrors create a duplicate of the map boss in the affected map. Killing both map bosses will unlock a new atlas mechanic: The Trial of Madness
After triggering the Trial of Madness, fog will spread from a map of your choosing on the Atlas including a locked Simulacrum. While inside the fog, the entire map is Delirious starting at 10%. Killing Rare monsters and the Map boss increases the Deliriousness of all maps in the fog. On reaching 100% the Simulacrum will become available. Deliriousness can continue to be increased up to 200% delirious.
Rare and Unique monsters in Delirious maps have a set of new Delirious modifiers giving them strange new abilities.
Map bosses of Delirious Maps can additionally drop a new set of 3 Potent emotions that can be used to craft new powerful modifiers on Jewels that are not available in the normal Jewel mod pool. These emotions can also be used to instill a set of 16 new Passive Tree Notables that are not normally available on the passive tree.
Simulacrum has been updated, and is now a 7-wave encounter.
Completing a Simulacrum will now give you a key to face the new Delirium Pinnacle Boss
There is new set of 10 Ancient Emotions that can drop if unlocked by the Atlas Tree which can be used to craft Timelost Jewels. There are also 3 Ancient Potent emotions that can be used to craft new powerful modifiers on Timelost Jewels that are not normally available in the mod pool.
Some non-amulet Delirium Uniques now drop with the Raven-Touched modifier allowing them to be instilled.

With Delirium receiving one of the biggest overhauls in PoE 2 0.5, players now have far more reasons to push deeper into the fog, tackle the Trial of Madness, and challenge the new Delirium Pinnacle Boss. From powerful Timelost Jewels and Ancient Emotions to revamped Atlas progression and exclusive loot, the updated system offers some of the most rewarding endgame content in the expansion.
