many may know this but here it is anyways just in case
takes place in neutral cities
you are able kill people of your own faction but you will also die mad.gif
All you need is a leather ball, the one you can throw around to players and to be standing in a neutral city (gadgetzan, area 52, etc), you also might want to be naked. throw a ball to them and see if he throws it back, if you can set up a nice game of catch going, throw your ball back to him and then immediately attack a player of the opposite faction, when he throws the ball back to you, they will enter combat and the guards will also aggro them.
