Okay, so he has a Daedric, Ebony, Stalhrim, Dragonbone, Dragonscale, and Glass armor and weapons from the game in his storage space in Legendary rating. 100 Smithing, Armor, and Weapon for the Skills(all perks).
Beyond that, the only Daedric artifacts he really kept were Dawnbreaker and Spellbreaker. He either got rid of or never received the others(seriously, who in their right mind would listen to Dagon or Bal? And those cannibals were dead in less than a minute)
He has Auriel's Shield on him as well as Auriel's Bow, though he doesn't use it that often as it was too dangerous for normal battles.
He has the Enchanted Spidersilk Clothes(+50 Armor rating), several pairs as well. Still has plenty of Silk left, too. Like, A LOT of it. Those spiders never seemed to end.
