Ah i miss those days XD
After finishing the game and replaying on the harder new game plus, once I got to this area and killed the boss. I actually died on purpose immediately after and then used the black stone repeatedly so I could fight other players. The PvP mode on this game was amazing.
My least favorite people to face in PvP are the ones that camp with two other people at the entrance waiting for black phantoms to attack(usually at 1-4.) The reason I dislike this group of people is the living player won't fight. He'll defend and stay away, if you kill any of his allies, a short while later he'll summon the exact same ally. I killed eight blue phantoms before dying one time. Later on I started using plague cloud against the people who did this.
