2. Setup Exitlag
1. Search "Black Desert Online" in the search bar. Make sure you select the correct one, NOT "JP" or "Launcher".
2. Select "Black Desert Online". Click Game Region tab then choose a route (Most people chose DE Falkenstein or DE Frankfurt because they are closer to game server). Then click APPLY ROUTES.
3. Make sure the Exitlag switch toggle is ON and the red dot under Black Desert icon is red.
4. Start MoonBD and enjoy your game! If the Exitlag successfully kicks in, you should be able to see the traffic right after you selected server.
