I feel kind of guilty because I ended up cheesing The Elder that way. Died the first time, went back, and he ended up getting stuck behind three trees and just standing there while I pumped fire arrows into him.

I like to build at least a small base around the bonemass skull, if for no other reason than that the liquid in the mount provides some free light.

One time I went a bit overboard and built a stone building all the way around, with tall walls, and even built a loft over top of the skull. Bonemass ended up spawning in the loft area and seemed to get stuck in the loft and roof structure. I don't know why he couldn't tear it down, but it was the easiest Bonemass fight ever!

That's actually my strategy for killing Trolls; run for gaps between trees and/or rocks that I can squeeze through, but the Troll has to go around. Gives me the breathing room I need to turn and take a well-placed arrow shot.

Another, similar strategy that you can mix with that, especially if your stamina is getting low, is to just slow down to a walk to let him catch up, which lets you build up stamina. As soon as you hear him start his attack, which he has to stop for a while to execute, sprint forward a bit, turn, and fire.

That's especially useful to keep his attention if he start to return to his spawn area. I hate it when I turn around to fire at him and he's walking away, and I have to chase him.
