Once you reach level 40 you will be able to PK or get PK'ed.
Open world PVP can be fun but dangerous, If your opponent doesn't fight back you will receive harsh penalties for your actions such as having your items durability reduced or possibly even losing some of your valuable.
But don't worry! If you don't like Pvping or PKing you will be able to active peace mode but beware: players in Slaughter mode will still be able to cause you harm.
Around the world of Nuanor there are peace zones where PVP is not allowed and guards are stationed to keep you safe. Here you can mend your wounds and prepare for future battles. For those of you still thirsting for blood, there is an island available where no penalties will be imposed upon you when killing other players!
