How the MU Online PVP System Works
MU Online’s PVP system features open-world combat, 1v1 duels, and epic guild events like Castle Siege. Attacking and defeating another player gives you PK status—earn too many kills and you risk dropping items and becoming a target for special monsters. Self-defense is allowed if you’re attacked first.
