I didnt notice a message and cant find anything in my inventory, am I missing something or is he just a dike?

I would imagine it would be the Spellbreaker shield? That's the only artifact associated with him I can think up off the top of my head.

Im dumb, just didnt see it before, it is indeed Spellbreaker. Heavy shield that reduces spell damage by 50 while blocking.

It is spell breaker. For more info check out my thread fficial Daedric quest information.
