The first mask I found was Raghot and I used it for a while but once I found a better combination I sold it. Now I I have found out that I need it! Am I screwed or is there some way to get this mask back? I have no clue where I sold it.

If the merchants stock reset then yeah you're screwed. But honestly most of the masks you find are better than the final one you can unlock, so I wouldn't fret to much.

If you are playing on a PC just use the console to put it in your inventory.

Search every store.

Haha this worked great! I had to hunt down the item code for it, but it didn't take long. In case anyone had a similar problem I found the codes here:

Thanks very much for the help!

uesp wiki has all the codes too, just need to know the name of the item so you can search for it.

I thought you meant selling Skyrim. lol
