If you want to change the max Level for Players or Thralls/Pets then you'll need to add some lines to a file on your Server.
1. Locate the File
Navigate to the game directory. The path is usually ../../../Games/Conansandbox/Config/DefaultEngine.ini or similar, depending on where you installed the game.
In the Config folder, find the file named DefaultEngine.ini.
2. Open the File
Right-click on the DefaultEngine.ini file and select “Open with”.
Choose a text editor like Notepad or Notepad++ to open the file.
3. Add the Section
Scroll to the bottom of the file or press Ctrl + End on your keyboard.
Add a new line and type in [/Game/Mods/Valkyrian_Lands/PreLoad/VAM_Settings.VAM_Settings_C]
This will create a new section in the file.
4. Add Entries
Underneath the new section, you can add the following entries. Each entry should be on a new line and follow this format: Key=Value.
▨ = NPC Level Curve ▨ = Player Level Curve ▨ = NPC Spawn Settings
It should look like in the image below.
Now you can change the True and False flag how ever you want to change the settings as you want. Please keep in mind that each group of settings only allow one True flag.
NPC_Vanilla until NPC_LVL_100 is one group.
Player_Vanilla until VAM_LVL_600 is one group.
Spawn_Vanilla until Spawn_VAM_All is one group.
5. Save Changes
After you’ve added all your entries, save your changes by clicking “File” then “Save” in your text editor, or by pressing Ctrl + S on your keyboard.
6. Verify Changes
Close and reopen the DefaultEngine.ini file to ensure your changes have been saved correctly.
7. Restart the Server
Restart your Server and the settings you changed should be now applied. Please keep in mind that already earned XP doesn't vanish so if you decide to change certain Level Curves it can be that already leveled up Thralls or Players will keep their higher Level.
