I think it is where yo can battle against a player.
Take a look on the world selection.
Go on a pvp world.
While on RuneScape PVP worlds, if you die, you only lose the items you are carrying, not those in your bank, never in RuneScape will a death directly affect your banked items.
yes you can because there are revs and other stuff
on the pvp/bounty worlds
you make 100k in runescape by going to pvp world and start killing people but before you go there, you have to be inthe widerness or edgevill.
You walk around in a non pvp world for around 10-20 minutes
yes
There are no banks in PvP zones but there is a safe of keeping 3 items UNLESS you are skulled.
You risk more items yourself, the more you risk the more you get. You get good drops if you are risking 25k or more on a pvp world. This means that you would lose it if you died, and it is not protected by the protect item prayer.
