Post here if you need help getting started with Daggerfall Unity or just want to clarify a potential bug. Questions about playing or modding classic Daggerfall should be posted to Community.
So the quest advanced fine, when I cast open (yes actual cast animation) on the chest it said it clicked open but when I went back to try and turn it in he said I was wasting his time and had something to do. I did have to rest to recover magic so not sure if that would effect things or not.
I am happy to report that I did get this spell to work. After you cast open and get the you found...message you need to talk to the person who you opened it for which will complete the quest. So far of the 5 boxes I have opened there was just graffiti in them so other then a faction boost I didn't get a reward. I can't recall if in classic I ever got anything from this quest as a reward either but it does seem to be implemented that you can complete it at least.
