Liquid Emotions

Delirium's exclusive currency. Three of them instil a notable passive onto an amulet; one of them enchants a Waystone with Deliriousness and a reward to match.

The game calls these Liquid Emotions. “Distilled Emotion” is Path of Exile 1's name for them and survives only in the internal item ids.

The ladder

Used on a Waystone, each instils a fixed amount of Deliriousness and, on nine of the ten, a reward to go with it. Deeper emotions are worth more and hurt more.

Potent Emotions

Three more, dropped by Unique monsters slain inside the fog once the atlas passive that grants them is allocated - one per creature type.

The game data gives all three the same Waystone enchant as Concentrated Liquid Isolation, the last rung of the ladder above. With ten rungs and thirteen emotions that looks like the table running out rather than a real shared effect, so we don't state one.

What else they do

Amulets Three emotions instil a notable passive onto an amulet, letting you take a notable from anywhere on the passive tree without pathing to it. Corrupted and Mirrored amulets cannot be instilled.
Jewels Used on a Rare jewel, an emotion replaces a modifier with a guaranteed one. The Ancient versions do the same for Time-Lost jewels - each jewel's own page lists the outcomes.
