Offline leveling (/offlevel)

/offlevel lets your character keep grinding monsters even after you close the game, using your MU Helper settings. The other offline mode is offline store (/offstore).

Step by step

  1. Start MU Helper (Home key), tune its attack / loot / buff settings and let it grind stably for a bit.
  2. Type /offlevel in chat. The character switches to offline mode and keeps fighting with your MU Helper settings.
  3. Close the client. The character keeps leveling, looting, buffing and healing on the server.
The MU Helper config window (open with Z): set attack range, skills, buffs and looting. Toggle MU Helper with the Home key.
The MU Helper config window (open with Z): set attack range, skills, buffs and looting. Toggle MU Helper with the Home key.
  • Costs zen: an activation fee (scales with character level) plus the usual ongoing MU Helper zen drain.
  • MU Helper must be running when you type the command.
  • If the character dies, it respawns and the offline session stops (no repeated deaths).
  • Pick a spot your character can survive, and keep enough zen for the ongoing fee.

General offline-mode notes

  • Each account can run only one offline session at a time.
  • Log back in at any time to stop it, all progress (exp, zen, items) is kept.
  • A server restart or maintenance stops the session, just log in and start it again.
  • Requires the latest client: simply start the game through the Launcher and it updates itself.
