Knight offers players an area made for Player Killing. These places are always packed with people and its full of fun! To compete with other people, you will first have to get good levels and gear. There are two places where you can PK. There's the DCZ, Ardream. This place is for characters from levels 30 to 59. In here, you can experience the thrill of PVP in game. The CZ, or Ronark Land is for higher level characters. It is open for characters of level 30 and above. Some highly dont recommend you to go in if you are not well geared and with a good level.
When killing opposing nation players, you gain what they call National Points. These national points serve for many purposes. When being in clan, the total amount of national points of the members determine the level. Also, the most NP Gainers of the month gain a symbol and other bonuses along with knight.
