Your Support

If you use this system and appreciate it, we're not asking for your financial support at this time. Here's a couple free things you can do instead.

  • If you're a GitHub user and you appreciate this system, please give us a GitHub Star.
  • If you're a Foundry Hub user, please endorse us or write a comment (happy feedback and constructive feedback appreciated).
  • If you speak a non-English language, ask about contributing a system translation. Sign up for GitHub and start a new Issue.
  • If you speak JavaScript, consider contributing code.
  • If you'd like to support the original maintainer of this system, U~man, buy them a coffee on Ko-Fi. It is largely because of U~man's generosity that we are able to continue providing a free and open source system for Foundry VTT users.

Troubleshooting and Requesting User Support

It's always appreciated when users submit an issue for all kinds of user questions, comments, and concerns. For those who prefer support via public chat, we recommend asking in:

  • The #dnd-other channel in the official Foundry VTT Discord server.
  • The #ose-virtual-tabletop channel in the official Necrotic Gnome Discord server.
  • There is a Discord server for Unofficial Old-School Essentials on Foundry VTT. Please ask for the invite link in one of the above places. We are sensitive to the possibility of spam and phishing attacks, so we do not post it on GitHub directly. This space is subject to the VTT Red Code of Conduct.
  • There are unofficial Foundry VTT user communities for many other languages if you'd prefer to discuss Foundry VTT in another language. Keep in mind that it's unlikely you'll find answers to your questions about a less popular game system like Old-School Essentials, but they are good for asking questions about Foundry VTT in general.
  • The /r/FoundryVTT community on Reddit may also have answers to your Foundry VTT questions, but it is another general Foundry VTT user community that may not have many users with specific knowledge about OSE. Be sure to write `[OSE]` in your post subject and select `FVTT Question` from the "Flair" menu.

We do not offer user support via email. Sorry for the inconvenience.


Any feedback is deeply appreciated. Please browse the open issues and if there's not a matching one already, open a new one. If you're a developer, look for our file.
