I box a 97 necro, 100 bst and me, 100 Mage with RoF T2 raid pet focus. This guy doesnt spawn off the scorpion, he spawns off the gladiator (sp) in the back room. I was able to tank him with the 3 box set and 2 100 cleric mercs. I only used the shammy and chanter for debuffs. Dropped the new pet focus ear, t3 group chest, 2 spell runes, and a ranged item.
In the building he spawns, there is a back door, with a small area only accessable by going through the building, I setup my camp there. You can go in the hall way from there, and pull the scorpion in the left room without anything adding. Then, you pull either the PH or the named. After that you can pull the scorpion in the room on the right, then the sisscar (sp). There is also a non named mob, with a name that roams from the ramp up, to the other ramp, that can be pulled sigle.
Granted, with my setup, I cant pull a lot, if addes are involved. But this mob was way easier than I expected a T3 named to be. But I was glad to get my new pet focus for my bst, now I just got to get my necro to 100, and get it for him also.
But, if he was designed to need 2 groups, someone failed.
