Me and a few friends managed to take him down today on Firionia Vie. (100 Shadow Knight 11,357 AA's; 100 Ranger 5029 AA's; 98 Shaman 1500 AA's; 99 Warrior 3894 AA's; Plus J5 Healers mercs)
Took us about 43 minutes, and we almost wiped. But, we brought him down. Atleast, our Warrior got his Rusty Axe he needed, and our Shadow Knight can summon his pet now. To be, fair we had to take him to the guards around 10%, so you could say we didn't beat him, but we you weren't there, you don't know what it was like.
