Smithing level high
You know that feeling when you acquire a particularly awesome weapon in a video game? Hours of work finally paid off and now you’re going to go wreck some fools. This thing will be covered in viscera in just a few minutes, and that will satisfy your bloodlust for a little while longer.
Now, aside from all the creepy psychopath stuff in that last sentence, imagine really having that weapon. And, imagine it being exponentially more amazing because you made the fucking thing yourself.
That’s what the Man at Arms crew did with the Daedric axe from Skyrim. The game requires that you have a smithing level of 90 to make this weapon yourself, and something tells me that these guys are well over that.
