Item Detector Achivement

[El Milos]

I recall some hidden items from the remake but this one is pretty hard, is there some missable hidden treasure that count for the achivement to unlock?

I have checked the guide for missables and I did get everything, fortunatley.

the two hidden items in South Western Saronia are missable. You can only get them by talking to two NPCs when the prince is in your party

[Maximus]

There is a guide for all missable items and monster entries here: https://steamcommunity.com/sharedfiles/filedetails/?id=2562531404

Other than those, you can check your map and see which areas are missing treasure chests or items.

I ended up missing those two of course. Didn't have a certain party member when speaking to certain old folk. I tried grabbing them in a separate file, but I'm guessing this achievement doesn't work like wayfarer?

I didnt get mini inside heins castle from the NPC so I had to start all over, it doesnt count like beastiary or adventurous wayfarer
