Killed him last night - he was exactly level 53 (yellow to 52, blue to 54). He dropped the bracer.
There are four spawns in his room. If you are looking into the room from the door, there is one on each side, one in the middle at the back, and one on the right towards the back. He spawned in that last spot.
Was expecting him to enrage at low health, but he didn't. Similar to a bloodguard with more hit points.
