amazingly i created a maxed out character and used dueled verse lords and king all i can say is you need seriously to be god-like as wu-long said to fight on equal playing fields with them (full 10 for every skill maxed out weapon usage, and maxed out str,agi,cha, and i forgot last one. I cheated lol i won't say how as this was my test character) best way that i found for characters to knock out lords and king are to either get loads of dead eyes or ride around chasing the king/lord shooting him in the head, while doing full gallop avoiding him. (head shots do hell lot more and also its much safer as long as you got your horse)
