I have added color coding to zones where PKs have been a problem. Despite my pleas to the Admins to block it – Reds sit in their houses, hidden, running Tracking, waiting for you to appear and/or spawn treasure map mobs. This a very poor mechanic that exploits players who may not be aware of the trap!
If you find a map in a dangerous zone, I highly recommend you just sell it off or bring 1-2 friends to help you. Player Killers depend on catching you alone and unprepared.
Tracking will not protect you – they sit hidden, running their own Tracking scripts back on you, playing a sound to alert them a new victim has arrived. Please be careful and just avoid these areas!
