They are for quests. I picked one up and tried the quest, still stuck in inventory and the quest will not finish.
I think the amulet has to be picked up after accepting it.
But a bit off topic, does anyone know the ID for the Talos Amulets?
I wanted to remove it using 'remove item [XXXXXXXX] [X]' but I don't know its ID. I did try 'removeallitems' and it kept a few items in my inventory including that damn amulet. But then I just did 'showinventory' to find the id for the next item and remove it but when I got to what I think was the amulet when I tried 'showinventory' it just said "Bad Editor ID" or something like that.
It svcks how they don't have a 'setquestobject' command in this game
