Player Killer
(Applies only to the Felucca facet, since murderers are not allowed in any other facet unless on shards with Siege Ruleset. Player killing has a long and storied history in Ultima Online, and we encourage players to visit Felucca to experience this for themselves.)
Anyone who attacks a Blue character is guilty of attempted murder. If the victim dies before the damage from a murderous attack is healed, his attacker is guilty of murder, regardless of whether he actually administered the killing blow. This includes damage inflicted by pets or summons.
A murdered character can elect to report his murderer(s). If you are reported in five or more successive murders, you are labeled a murderer, and you will highlight red to other players. See: Murder Counts
Murderers can enter towns without being attacked by the guards; however, if they choose to harm any citizens during their stay, they will be quickly dispatched by the local authorities. (This only applies to the Felucca facet.)
Reds (Also known as Murderers or PKs) May not use any virtues while they are murders. They may however, gain virtues such as Valor and Justice. Though they may be "Knight" in any given virtue, he/she will not be able to invoke (use) them until he/she has worked off his/her murder counts and is "Blue".
Murderers will not be able to gain certain Virtues, or use any Virtue abilities, as murdering innocent people is not a very virtuous activity.
