These particular mobs may be found in tunnels in the North East portion of the map (tunnel openings are at Location Pos+335, Neg-520). The Undead Thief and Plagued Slave are also in these tunnels. They appear to have a very short aggro radius, though I pacify to pull regardless. I estimate 17-18K HP's on these mobs, having parsed out nearly 19k in damage output during a fight, and accounting for regen of mob. Max hit by mob was for 326. Somewhat resistant to magic based casts, so malo or tash doesn't hurt. Slowable and mezzable. Since my main is an enchanter, this is basically all the observation I have on these.
