Player Kill is called PK for short.If you are attacked by others,just show your confidence in your ability and put up a good fight.
Frist of all,you can estimate other players' level, HP or MP through any equipment they are wearing.Donating items at an Altar of Goddess in each of the village areas to earn positive Morality points so that when you enter PK mode and slay another player, you can avoid going negative on the Morality scale and gaining a Red Name.it's dangerous if you get a Red Name,anybody can attack you without PK mode on and less experience points per kill will be gained.
Attacks are either Physical or Magical.the Magic defense is useful only when your opponent uses magic attack skills.the larger the total attack points are compared to the corresponding total defense points, the greater amount of damage will be dealt.Don‘t forget to do your character building first before PK to gain good attack and defense,including good weapons and armor, suitable character's Skill Tree,level upgrades.
