MMORPG.com Runescape Correspondent Faisal Baig writes this new guide to PvP in Runescape.

After the Runescape update, the wilderness and basically player killing itself was eliminated and replaced with PVP worlds. PVP worlds, or Player-Vs-Player worlds, are entire designated worlds that are almost entirely Player-Vs-Player combat enabled. Think of it as almost an all-over wilderness. This thorough guide covers the many aspects of PVP worlds.

In PVP worlds, only select areas (such as banks, respawn points, Entrana, and some guilds) are disabled to combat, and are marked by a skull with a cross over it. These worlds are modeled after the original wilderness, and many of the same rules apply, such as level restraints to attack and "skulls" when you attack someone. To begin, simply choose a world that is marked as a PVP world when logging in. You will be warned of the obvious dangers. The first time you enter a PVP world, you will be transported to Lumbridge, and a manual will be given to you explaining much of the concept (you can get a new one from the Doomsayer in Lumbridge should you lose it). When you first log in, you will have a short immunity period before you can be attacked. In PVP worlds, you can lose your items, but at the same time, there are great rewards available!
