You got every daedric armor piece? There's more than just the chest piece, and theres also the daedric weapons. I know the daedric 2h sword is bettwe than chrysamere. There's also an underwater cave south west of the city vivic with some really cool stuff. Try killing vivic himself, i can almost gaurantee you won't kill him
If you want a full set of Daedric armor, find the guy who cured you of corpus. I think hes in Sandrith Nora. hes got a full set of the armor. The Daedric dai-katana and the daedric longbow are also badasss weapons
