Has this mob become very rare? I had some time to kill so decided to camp this decent "counteract poison" clicky but have cleared the whole pyramid at least 12x without seeing even his spoor.
He spawns at 4C, he was roaming on the north wall. Me and a 64 druid took him, I'm a 65 monk with elemental equip. He hit for 270 max, hit pretty fast too. The toughest part is getting there, I would pacify the see invis mobs and FD and the druid would run past (there is a see invis monster at each corner of the courtyard thing in 4c). We got to the northwall, timed the kill between the roamers that go by there. They aggro'd at around 5%, druid rooted them, looted and succor'd. His actual name is Terrorclaw. I have a picture of him too.
Took him today doing c4. He hits about the same as the other raptors around the area, which is to say up to 270 a hit and someitmes 500 a round, but he is easy if you have a grp capable of doing c4 anyway. He may have a few more HP than normal but it isnt really noticable. Can be slowed and has no procs. Dropped the necro shoulder piece ( Seems to be a random spawn for any of the wandering raptors, but we found him on the backside/north side of the pyramid.
