hardcore
Once a person has declared himself a player killer he has the oppurtunity to become a HARDCORE pkiller. This allows him to loot any items left on the opponents corpse providing your opponent is also a Hardcore pkiller. After, of course, the appropriate amount of dancing, taunting and everything else that comes with a successful pkill. Hardcore killers get an additional 10% exp bonus on top of their pkill exp bonus.
