These guys run at sow speed. I am not sure if they are immune to snare, i got message he had been snared, but he was still able to keep up with me as a 66 ranger. Casts the Cleric spell Reckoning and heals. Max melee hit was 429 but that was uncommon.
The ones with swords/shields do not cast. The ones with mauls or no weapons do. They also heal. Both kinds are very rootable and mezzable. None of them summon. Very easy to solo with 73 ranger.
