Player killing

Player killing (abbr.: PK'ing), or player vs. player (abbr.: PvP), is the act of two players in combat, instead of a player and a monster or NPC. At present, there are only three places in RuneScape where player killing occurs: the Wilderness, the Castle Wars members minigame, and the Duel Arena members area.. However, there was a time in the game's history that the entire map was open for player killing.

In RuneScape Classic, players can duel anywhere.
