Blood Money

Age of Conan has a Blood Money system, which is basically an alternative currency that you get when you fight and kill other players in battle. Blood Money can be used to purchase equipment and benefits that are not available for purchase with regular currency. Fighting other players does carry other benefits as well, as you have a separate advancement system for PvP in Age of Conan.

Much like the WoW system where you can purchase to PvP gear and doo dads.
