In this system, players receive "honor points" in PvP, among other things. If the PKer is over 10 levels higher than the person, then the victim will not lose any experience, and the PKer will not be recorded on their "Killed By" List. However, anyone below their level will be recorded on the "Killed By" List and Honor PvP items will be shared with them. When someone is recorded on that list, the person who was killed will have the change to use the "Vengeance" system. They can choose to bring along a party to kill their PKer, and if they succeed, then that name will be wiped off the "Killed By" list and PvP Honor items will no longer be shared. In the same way, if you kill someone below 10 levels from you, then his name will not be recorded on your "Killed" list.
