In the quest from Herkir called "From Dusk the Dawn", he tells you to go get Gath Duskwraith's spear. But the boss' name and the name it tells you on the pad outside his cave is Dustwraith.
By the name of the quest, it would seem Duskwraith would be the accurate name rather than Dustwraith. I think it should be changed so the quest matches the boss.
