At 56, he is quite easy for a mage. I used 51 earth with muzzle and plate, and buffed with BO4 and Cadeau of Flame. Pulled with Malosi to help with damage and pet rooting. Tag with 3 Lavabolts and it will leave pet at about 50% health. Easy to med while pet heals until repop in about 6 minutes. The down side is experience. I killed him three times tonight and didn't even get 1% (with all experience going to leveling). Easy, but not worth the time IMHO. And no, I never had any guard adds at 56. Good hunting.
I had some problems killing him with my 55 Mage, he is by a house and he has 2 guards next to him. If u pull him at least 1 guard will assist him, he hits hard and fast, I had to kill him and the guard and it took 2 earth pets and a long time to kill them. I personally don't think it was worth it onless u can single pull him everytime.
