MPK (Monster Player Kill) is a form of player harassment that has plagued many MMORPGs. MPK involves using one's character to purposely cause damage to other players or to unfairly take another's claimed target in the midst of battle. Several measures will be introduced in the next version update to counter these issues.

The upcoming measures are intended to deal with issues regarding the acquisition of items and claiming of monsters, rather than focusing on direct involvement in player disputes.
