Characters that attack a gray or low moral character will no longer be flagged into a mode where they can be PKed by anyone at any level if they are within PK level difference of the gray or low moral character they attack. In other words the character is only put into the above mode if they attack a gray or low moral character outside of the PK level difference.
The change will allow characters to defends themselves against gray or low moral characters within their level range without having a higher level character jump in and attack them.
