I got a dwarven mace out of one last night. Thing basically took out a dragon for me. Now I just need to refine it.
Oh and this^
I got a lot of unique gear last night by breaking into some places. I don't really use my new gear though. I'm a lot more content with running around with my pickaxe and killing giants, mammoths and dragons.
Last night I went to engage a dragon with the pickaxe and a mammoth came over and took two swings at it and helped me. After I took the soul the mammoth and a giant nearby turned on me so I killed them with my pickaxe too.
