For those of y'all who think Byrd of Prey is a monster. Wait till you get a load of Stonez!! Walking tank with as high as level 40 heavy armor, and swinging a 371 DPR battle flail. Each shot from him will take out on average 500 health points.
Delta took out about 400 health points on him before going 6 feet under, and still had a long way to go.
