The build doesn't seem finished, but regardless it was his skills and game sense that really played a big part in this dungeon conpletion (alongside with vamp guild).
Berserking Armor (Likely Berserking enchant?) Sharp Ring? Not sure they're bleeding. Rage Rune Vamp Guild Sporeling Arachnid Winter Woof? Would only be there if Sharp ring is used Can't tell what handle he's using, but it's likely phys scaling, and it can't be two handed or long (to make unbalanced blade).
