Old-School Essentials Third Party Products


As products are released for Old-School Essentials using the third party license (see the license here), we'll keep this list up to date so that it serves as a repository of all products released specifically for OSE. (Also remember that anything released for B/X or other compatible games is usable with Old-School Essentials as well!)


  • Third party products are not affiliated with or approved by Necrotic Gnome.
  • Links to DriveThruRPG are affiliate links, so purchasing via them supports Necrotic Gnome as well as the third party creator!
