The wiki lists six "fortune" buffs among the various odd misc bonuses. It's very possible that this list includes everything someone managed to data mine, and not all of it is available. Still, I decided to do some digging.

There are six strings among the status effects (statuseffects.gamedatabundle) along the theme of boon_nisanga_constitution and so on, one for every attribute. Searching various files for nisanga, I found

"$type": "Game.GameData.WorldMapEncounterGameData, Assembly-CSharp",
"DebugName": "RE_Fortune_Teller_Lady_Nisanga",
"ID": "99febfc0-de86-4517-84ef-fae2e7bd518e",

(worldmap.gamedatabundle)

There are two other fortune tellers referenced above and below her. One is called Lady Abimi, another is called Unnamed Watcher. Judging from other entries in this file, these are random Neketaka street encounters, ones you get when traveling between city districts, like for example the oozes and the well event (I also believe RE means Random Encounter 😛).

Yet, with way more time sunk into this game than I'd like to admit, I cannot recall ever meeting any fortune tellers. Certainly not as random Neketaka encounters. Anyone have any ideas? Your Watcher stands to gain +1 to an attribute here.

Never met any other fortune teller than the "Fortune for a pand, good sir?"-pinocchio in the Dark Cupboard.

I'm embarrassed I didn't think of him in all this brainstorming. Let's see if anything happens if I spam feed him pires pands. Maybe he's the Noober of Deadfire.

That would at least explain why he's there (besides the story of him and his compagnon trying to rob Arkemyr resulting in helpful notes for any following thief).
