I did this the first time tonight with 105 ranger, 105 necro, 105 bst and his 101 pal box...1 healer merc on hand but not needed at all. Stationed the necro and bst at 2 of his pause spots, and I ran the ranger in the middle of the rough circle he runs. Necro started us off with a long term dot, and i chased him burning what i could as he ran about, staying in the central circle and getting bow range as often as possible. Bst had pet on him, just too look nice, and necro reupped dots as he ran by. Semi long fight, but done in a pureshot disc. No adds, no frills just keep hitting him so he doesnt start to regen
