this requires a lv 70 paladin, or a friend with a lv 70 paladin, or at least a few trolls blood potions....
head on down to the blasted lands and grab the quest, petty squabbles. do the first 2 parts till you are on the part called, the stones that bind us. find a servant of razelikh, pull him away from the stone, if you are on a paladin or have one helping, use seal of light and judgment, this will keep your health toped off.. now just beat away on the lv 57, he will stay at 1% health. I did this the other morning, started the fight then went afk, you wont get dc'd either since your in combat, came back an hour later to a skill of 350, switched weapons and did it again....
