Delirium
Delirium now has a clearer Atlas identity, deterministic quest progression, a revamped passive tree, and new escalation mechanics that point toward a dedicated pinnacle boss.

What changed
- Delirium has a new Atlas hub: The Withered Willow, south-west of the Atlas start.
- Maps around the hub always contain Delirium and grant points for the Delirium Atlas Passive Tree.
- The Delirium Atlas Passive Tree was completely revamped with new and changed nodes.
- After touching a Delirium Mirror, a new bar shows fog depth and time remaining.
- The fog direction now points toward the map boss, and Delirium map bosses are always 100% delirious.
New progression
- New mirror-shard encounters appear at certain depths on the Delirium bar.
- Completing Delirium Mirrors can spawn Grand Mirrors on nearby Atlas maps.
- Grand Mirrors duplicate the map boss; killing both bosses unlocks The Trial of Madness.
- Trial of Madness spreads fog from a chosen map, raises Deliriousness through rare monsters and bosses, and opens Simulacrum at 100%.
- Simulacrum is now a 7-wave encounter and completion grants a key to the Delirium pinnacle boss.
Rewards to watch
- Loathsome Mire can drop two new amulet bases that grant two instilled notables with a prefix or suffix tradeoff.
- Liquid Emotions can craft jewel modifiers, similar to greater essence behavior.
- Potent emotions can add powerful jewel mods and instill new notables not normally found on the passive tree.
- Some non-amulet Delirium uniques can now drop Raven-Touched, allowing them to be instilled.
