This raises the charm limit to 100 creatures
Download the BepInEx ZIP File from the official BepInEx repository. I have used version 5.4.21 found here
Use the version that is right for you. In most cases, this should be BepInEx_x64_5.4.21.0.zip
Extract the BepInEx ZIP File into the games "root" folder
3.1. To elaborate: Download the ZIP File from the link above, then extract its contents into the main folder of your WWAG Steam Installation. This is most commonly under:
C:\Program Files (x86)\Steam\steamapps\common\Wizard with a Gun
When finished, you should have a new folder called BepInEx in your WWAG Game folder, as well as a few new files.
Run the game with BepInEx Installed atleast once. This will generate needed Config files and folders in your WWAG Game directory
Close the game
Wizard with a Gun\BepInEx\plugins\WWAG_CharmArmyThe mod should now be installed.
