PKing is a type of PvP that does not require a targeted character’s consent.
PKing has certain penalties, and the more you PK, you will receive severer penalties.

Starting PK

Click a target character, and use the Shift key and a skill button to initiate attacks. You will receive a message informing that a PK has started. If there is no interaction between the two characters for a set duration after a PK is started, the PK will be automatically ended.
[Tip] You are allowed to use HP Potions while PKing. Use Fade Step (Sword Skill) or Tumbling (Social Action) to avoid being targeted.

PK Penalties

• If you attempt another PK while in PK Penalty status, you will lose 1,000 Honor Points.
• If you kill a character while in PK Penalty status, you will lose 10,000 Honor Points on the top of the 1,000 points that you have lost by attempting a PK.
• If you continue attempting PK while in PK Penalty status, the severity and duration of penalty will be increased.
