Killing a Calpheon Shadow Guard results in a high chance of Corrupt Crystal drops; similarly, file corruption may be a result of high system stress. How and why this happens is a long technical adventure only for the brave ones out there, but there is an easy solution in case you are affected.
Repair via the game Launcher
- First, start your Black Desert Online Launcher and click on the cogwheel icon on the top-right corner of the window.
- Press on the Click To Start button, right next to the "Repair Mode".
- Choose the Yes option.
Note that while this may look like the Launcher is re-downloading a massive amount of data, only damaged and missing files from your installation folder will be downloaded. You can confirm that this is the case by the Checking Files text located on the bottom-left of the Launcher window.
Forcing a file repair
In case the repair button is not clickable or in a grey state even after logging into the launcher, you can force the Launcher to go into repair mode by deleting the version.dat file found on your game installation folder.
What about Steam?
If you are using the Steam platform, you can verify the integrity of your game files by using Steam's built-in file checking function. To do this, follow the steps below:
- Restart your computer, and launch Steam.
- In your Library, right-click Black Desert Online and select Properties at the bottom of the menu.
- Select the Local Files tab and click Verify Integrity of Game Files:
- This will verify the files and replace any corrupted or damaged files. It can take some time to go through these files.
- Some files may come up as "failed to verify". That is normal behaviour as they are local files that won't be replaced.
