So I started a new character the other day, in anticipation of Dragonborn DLC. And I remembered that in a previous playthrough (that I delected) I fought off a daedra lord and got a unique mace that has knockback. I wanted to know where I can find it again but apparently no one knew the answer. I thought I remembered it wrong, but then I found one of my screenshots.

But now I can't remember if this was in the vanilla game or modded version. Can anyone share some insight?
