yeah, but you already kinda know what's going to be in a chest by it's design, and the jars aren't really that hard to spot / don't offer much besides like 2-3 drachmeThe sight is to find jars or other small containers and identify which chest has valuable loot (white/blue/purple/gold markers/dust). Iirc the eagle doesn't reveal the content of a chest, just its location, cannot mark enemies behind more than 1 wall and if of course unaware of objects not on the completion list. I don't think the eagle ever tagged enemies inside a cave for me...
It never revealed any hidden paths for me (it did not highlight around cracks in a wall)
I've been able to get the eagle to spot enemies through caves by going to the entrance and then just looking around, eventually he will tag the leader/gold border, and usually a few enemies too (although I didn't know about the wall limitations, which would explain why he doesn't spot some enemies on lower levels)
even so, the range of the sight is so limited that by the time I could actively tag enemies, they'd have already spotted me, or I'd have spotted them and manually tagged them with my bow
I'm just a bit frustrated with it, bc the one situation in which it would have justified the ability point investment, it simply didn't work at all, so I think I'm just going to respec out of it later
hopefully they patch it and buff it, or do something bc right now it's like you said, a ability that points out the little jars and what color loot to expect from chests
