Ended up killing this guy several times while camping othni pieces for alts. He can be camped from the zone in area. Clear the roamer at zone in, then the 2 guards at the door to the courtyard. For me, he popped every time up the ladder on top of the door that leads from zone in to courtyard. Looking at the door from the courtyard, he was to the left of the door. PH was a broodling and maybe a warrior.
Hits for around 2K+ max. Has about twice the hit points as the courtyard trash mobs. Killed him with my regular group (me=83SK/pet/cleric merc).
So far has dropped shield, hammer and several othni pieces.
