Drops off "a goblin dustscryer " (Level: 35)
His cycle is that any one of 3 different mobs can be a ph for it across 3 areas of the zone. Northwest, Southwest, Southeast. Once you kill one of the PH's .... another ph (or a goblin dustscryer) IMMEDIATELY pops.
I have compiled a list of all the mobs that are part of the cycle. Named mobs are obviously what they say, Named Mobs... Unique Mobs are mobs that they have unique names... and will only be one of them in the zone. They are specially named versions of common zone mobs.
