I absolutely hate adding PK rules to HELP PK. However, we do have some rules for raiding cities and I want to clarify things. None of this should be new to you. Before I post this in HELP PK I want to open it to discussion here.
8) Cities and councils are considered defender zones. If you attack a city, you cannot retaliate later for any actions taken against you (or any loyal mobs) while are you in that city. If you defend your city by attacking a raider, the raider may then attack you. However, you cannot be retaliated against later unless you pursue the fight outside of the city. Attacking players cannot kill players in cities unless they have valid RP reasons. Raiding a city opens an attacker for PK, but if that PK occurs outside of the city, the defender is no longer immune to retaliation.
This includes doing things like leaving your mobs in a city waiting for someone to kill them so you have a reason to kill them later. I have no problem with leaving your loyal mobs around in an attempt to bait people to kill them so you can PK them later, but leaving them in a city is the same as raiding that city. You can attack them right then, in the city, but not later, outside of the city.
