Met this guy the other day on Druzzil Ro server while camping the necro. He spawns on top of the hill in front of the steps, dunno spawn time but I'm guessing the skellys and mummys that spawn on the hill are his PHs.
Anyway, saw him, conned yellow to me (31 druid) medded to full, and basically ensnared/dotted him to death. Will admit he did break root many many times and very quickly I might add, so eventually I stopped rooting to save mana. All in all he wasn't incredibly tough, though he was pretty fast even ensnared and hit pretty hard so keep your distance and kite him if you can. Noticed that if you get a certain distance away from him(not that far, was still in sight of him) he kinda just wanders off and leaves you alone, oh well lets you sit and med. =) But once you get back in his range he comes a runnin'.
Hope this helps
