The Doylak master I ALWAYS encounter is right after Kilroy Stonekin, and is in the route you give in your little map.
Edit : Let me try and do this again and show you where it is.

I find that group to be quite easy. You just have to apply pressure to the Ice Golems, and Grenth's Balance/Bonetti's,Doylak Signet, and Healing Signet up. It's the next group I COULDN'T get past ; however, those first 6-7 times were the ONLY times I had ever been down there, so now that I've stance tanked a bunch, I know the ways the group move now.
, but great build 


I suppose it would, ya know, since your going up against dwarves and all. But 60/-3(Hexed)Shield might be better
