As a rule, killing other characters is legal on all game worlds of Tibia where player vs. player combat (PvP) is enabled. However, there are differences. There are no limitations on player killing at all on hardcore PvP game worlds, while there are certain restrictions on worlds with open PvP combat to make sure player killing does not get out of control. On optional PvP game worlds, player killing is only possible if both sides agreed to it.
Note: A character cannot attack other players in the first 10 seconds after login, unless he is attacked and needs to defend himself.
a) Player Killing on Hardcore PvP Game Worlds
On hardcore PvP worlds there are no restrictions whatsoever on player killing. Quite the contrary, attacking and killing other characters is actually encouraged. In addition, the spell "cancel invisibility"
b) Player Killing on Open PvP Game Worlds
On open PvP game worlds a limited amount of player killing is allowed and kills are divided into 2 categories, in "good" kills, i.e. kills of marked characters, and in "bad" kills, i.e. kills of unmarked characters. A character may make any number of "good" kills, but it is not allowed to make too many "bad" kills within certain limited periods of time. For details on how characters are marked please see the next section.
Please note that the last 20 characters that inflicted damage on a character in the last 60 seconds before his death will all be recorded as "good" or "bad" killers, depending whether the killed character was marked or unmarked for them.
c) Player Killing on Optional PvP Game Worlds
On optional PvP game worlds, player killing is only possible within the scope of a guild war. Only characters who are involved in a war can attack or inflict damage on each other. Moreover, characters cannot walk through characters and their summons with whom they are at war.
Note that neither your weapon nor your shielding skill will improve by attacking other characters or their summons during a guild war on an optional PvP game world.
d) Skull Marks
Skull marks appear only on open PvP game worlds. A character that has not recently been involved in any violence is unmarked. You will not be able to attack such a character if your combat controls are set to secure mode.
If unmarked characters are attacked or hurt by another player, the attacker will receive a mark which will be visible to all other players as a little skull underneath the name. Once a character is marked all other players are free to attack this character! A character that attacks or kills a marked character will not receive a skull mark himself. Therefore you can kill as many marked characters as you want to without risking a red or black skull. However, if you plan to attack a marked character, you should still be careful, because, like everybody else, marked characters have the right to defend themselves. Whenever a skull mark is about to vanish, it will flash for about 5 seconds. During this time the skull mark is still valid but you know that it will be gone in a moment. Please note that not all skull marks indicate that a character is truly a player killer, even though any marked character may be attacked. The skulls come in 5 different colours:
White Skulls
A character marked with a white skull has recently attacked or killed an unmarked character. All players can see this mark. It will stay as long as the logout block is active. If the character performs further offensive actions while he is marked with a white skull the duration of the mark will be extended, as will the duration of the logout block and of the connected protection zone block. Still, white skulls are temporary marks which indicate that the marked character has been aggressive recently.
Red Skulls
Characters that kill several unmarked characters within some periods of time will be marked by a red skull and have to face serious sanctions for their player killing. This happens when a character kills 3 to 5 unmarked characters in 24 hours,
5 to 9 unmarked characters in 7 days or
10 to 19 unmarked characters in 30 days.
As soon as a character reaches one of these three limits, the character will be marked with a red skull for 30 days. Note that every time one of these limits is reached again the red skull mark is reset to 30 days. Also, as an additional sanction a character marked with a red skull will drop all items in case of death, even if a character has all blessings or is wearing an "Amulet of Loss"! This will encourage players to hunt and to punish the player killer.
Black Skulls
Characters that even cross one of the limits for a red skull, will be marked with a black skull for 45 days. Characters receive a black skull when they kill 6 or more unmarked characters in 24 hours,
10 or more unmarked characters in 7 days or
20 or more unmarked characters in 30 days.
Every time one of these limits is reached again, the black skull mark is reset to 45 days. Just like a character with a red skull, a character with a black skull drops all items in case of death. In addition, characters marked with a black skull cannot attack any unmarked characters. So be careful, if you attack several characters when having a red skull, and then one of these characters dies and your red skull turns black, you will no longer be able to attack the characters you have attacked before. As you have attacked these characters first, they will also not get a yellow skull. This effect will stay for as long as you have a battle sign.
Moreover, characters with a black skull cannot use any aggressive area spells and runes, beams and strike spells that are not clearly aimed at a target, burst arrows, and any summon spells and runes, such as "Undead Legion" or "Convince Creature". Also characters will lose all summons they had before getting a black skull as soon as they are marked. Further, they will receive 100% instead of 50% of the dealt damage in PvP fights. Finally, if a character with a black skull dies, he will awake in the temple with 40 hit points and 0 mana.
Yellow Skulls
This skull is somewhat special because it is not visible to all players on the screen. You will only see it if your character was attacked or damaged by another character first when your character was marked with a skull. This happens because you have the right to defend yourself also if you have a skull. If you kill a character with a yellow skull, the kill does not count as a "bad" kill as any other kill of a marked character. Similar like a white skull, a yellow skull will stay as long as the logout block is active. If the character performs further offensive actions while he is marked with a yellow skull the duration of the mark will be extended, as will the duration of the logout block and of the connected protection zone block.
Green Skulls
Green skulls are another special case. A player marked with a green skull is either a member of the party you belong to or is a member of your guild or the opposing guild if you participate in a guild war. Like any other marked character you can attack or kill party members without any negative consequences.
e) Good Kills vs. Bad Kills
Some words on "justice" on worlds where a moderate amount of player killing is allowed. Of course, every automatic system has weaknesses. Players may try to abuse the protection offered by this system to provoke you in any conceivable way. Still, you should always think twice before attacking an unmarked character, no matter what he has done. You may have good excuses for attacking the character, but your fellow players may not accept them. It is not the goal of the marking rules to ensure justice but to handle most typical conflicts arising in the game in a fair and neutral way.
