roaming "a wandering ghost" in the area (location unspecified)
"Lingering Sorrow" is cast every 20 seconds on random target (but not most hated). Every 25 seconds, he ports to a random player and AE rampages for a bit.
Killed him today 12-2 12 he dropped both items. group was a pally, druid, monk, and 3 necros. we wiped the floor with him. levels ranged from 95 to 97 and all raid geared. His port around to each player was a bit annoying but the pally had great agro and it never hit anyone else as the whole group stayed tight together. I group is spread out a bit i can see how it could be a problem.
