As a side note: Have a evac ready when you go down to fight Gydek. He calls a hoard down on ya when he gets to 60% health and you'll be fighting like mad. Kill him,focus solely on him,then get the heck outta dodge with the evac,otherwise some in your group may not survive....
Very nice bow, but also a long quest. This is longer than some heritage quests, as you have to camp a lot of named and rare-spawn mobs (ie. Defiled Priests) in order to finish it. Everything except the final mob (Lord Gydak) was solo-able at level 28, you could probably even solo it a few levels lower. You'll need a small group for the last mob, which is in the lower caves on level 4 of Stormhold.
