4. Mobility and Fog Manipulation
Mobility skills in the Delirium passive tree help you maneuver within the fog, ensuring that you can stay within its boundaries while avoiding incoming attacks.

Increased Movement Speed: Fast movement is essential in Delirium, as you need to stay within the expanding fog while avoiding large groups of enemies. Passive skills that increase movement speed can be pivotal.
Fog Manipulation: Some Delirium passive skills affect the expansion of the fog itself, allowing you to control its spread and make the encounter more manageable.
Fog Mastery: Some notables may allow you to benefit from being inside the fog more effectively, giving you buffs or debuffing enemies while staying in it.
5. Delirium-Specific Buffs
Certain skills in the passive tree give you buffs that are specifically tied to the nature of Delirium encounters.

Fog Empowerment: These skills grant bonuses that only activate when you’re within the Delirium fog. They might increase damage dealt or resistances while you stay in the fog, rewarding you for staying in the fight and maintaining your position.
Enemy Debuffs: Some passive skills may debuff enemies within the fog, making them easier to kill. This might include reduced resistances or lowered damage for Delirium monsters.
