I want that claw now. I need an awesome helmet.
The helmet quest is radiant, so there's a number of places the quest may send you. One of them is Yngol's Barrow, so my experience is it's best to get the quest from the Jarl before you go there. I have had it bug out and not spawn the helmet when I've already visited the Barrow, but have also seen advice opposite to this. So my best advice is
always save before you do either.Yngols' Barrow is too cool a place to be distracted by stupid bugs.
