Makes me think you can add scent trails to many objects- like the path of a fired arrow. Would help mitigate the "stealthy archer" problem Skyrim AI has.
I’ve been playing AssCreed Odyssey as a stealthy archer and it’s solution to that particular problem seems to be attaching your location to each fired arrow; enemies within some radius of where the arrow hit are given a search target somewhere near your position when shooting. Add in some “It came from over there!” barks and it works pretty nicely
If you are far enough away there is a big hole in this wherein they can’t get to your position before their maximum-amount-of-time-in-search-mode timer fires off and they go back to their normal location and behavior, though.
The "stealth archer" build in skyrim is overpowered since the enemy AI can't usually know where the arrow came from, and they tend to aggro, look around their immediate area, then go back to the idle state allowing the player to shoot them again from a safe, hidden spot. Rinse and repeat, and almost any encounter in the game with hiding spots is trivial.
