Kill on sight


 * Were you looking for the poster in Kargath titled KILL ON SIGHT?

The term kill on sight is a status of enemies (usually shortened to "KOS"), usually towards other player characters in PvP, to members of an organization like a guild. Supposedly, when these enemies are seen by members of the organization they are supposed to try to attack and kill the target if possible.

In World of Warcraft, there is no formal mechanism for tracking these enemies, but some other MMORPGs allow you to make an in-game list and sometimes even highlight these targets in the game in some way.
