During one of Larian's streams the question came up about bound items (unremovable by players) similar to the source collar. The Devs liked the idea and would look into it. Would like to know if there's an update on that?

Another question is about chests. I presume you can set the difficulty on the lock? But is it possible to set key items to open certain chests or simply make it locked for the GM to unlock for the players?
