So just to cover the obvious. You're hitting Moder most of the times yes? At full power? Cos dividing his Wiki reported hp by the dam val of obsidian's (no not including the bow damage add) you 'd only need 200 or so? As Max says above?
What bow are you using I guess we're all assuming A Draugir Fang (Because why not?!) but you tell me please?

You don't even need anywhere hear that arrow amount.

On a Bow-only run that I did, using Needle Arrows and Level 4 Draugr Fang, Moder died in either 60 or 80 Needle Arrows; can't remember which one it was. Now, your Bow skill probably isn't as high as mine was, and you're also using arrows that do a bit less damage, but Moder should be dead in around 120 at most IMO.
