You can set up in pretty much the dead center of the room. You will be out of aggro range of The Blade and the adds. Tank him in the East corner to make sure the ranged characters are out of range from Dancing Blades.
He casts Dancing Blades every 45 seconds, it goes off 5 seconds after the emote.
He has 46m hp. The enrage timer starts at about 10min. We killed it around the 13min mark and he was hitting for about 60kish.
The aug has dropped 1 out of 4 kills so far.
