Notes from author
All the instructions for this build are here http://i.imgur.com/mNuo6.jpg
-You can replace the Wolf ring with something else (or just remove it altogether) if the poise buff's aura bothers you.
-Throw in some tactics that a Darkwraith mob would use: spontaneous kicking, Dark Hand grabbing, running attacks (the way the mobs do it), and/or two-handing the sword.
-You can bump your END up a couple notches or put on Havel's ring if you want to midroll for the reasons mentioned in the pic.
