Killer status. Reputation
Player Killer status
By attacking another player you get the status of Player Killer or PK. A yellow triangle will appear above the head of your character and your reputation will become worse.
Possible meaning of reputation
The more you attack (even without success) the more red tint gets this triangle and the worse reputation you will get. In such a way one can distinguish the most blood-thirsty killers. Though in game no sanctions applied to the killers but your reputation in the playing society can become worse.
How to restore the reputation?
The mark of a killer disappears if you undergo the attack of other players or monsters. The more health you lose at that the quicker you restore your status.
