I have collected a bunch of these circluar medallions (exact name?) throughout the game, but I have not been able to use them on an item. How do you do that?
if they are amulets then then you can wear them. are they charms? those are for enchanting stuff. thats all i can give you untill you tell me more about the items.
if they're named something like pag-ikor or something like that, you need to have the enchant weapon skill. if you do have a level or more on that skill just click an equipped item and a window will pop up with slots for charms
