Foreword

This is a fan-made Tabletop RPG content add-on based on Touhou Project. It is compatible with D&D One (5.5e) books and SRD 5.2 (CC-BY licensed subset of D&D One rules), and doesn’t include full rules.

If you don’t already have core rules, you can get a free copy of SRD as official PDF or unofficial markdown conversion. You don’t need Species, Subclasses, Backgrounds, etc. from official books to play this addon.

If you need more information about Touhou Project, you are encouraged to read Touhou Wiki.

Notable changes from SRD:

  • Custom Species, Subclasses, Backgrounds and Feats (including new “Youkai Feats”);
  • Youkai creature type, replacing Monstrosities. Fiends are also considered to be Youkai for abilities that require it;
  • Special named attacks called Spell Cards;
  • Death is automatically avoided in most battles;
  • Backgrounds have a Residence field that gives player a living place.

If you want to fix some mistakes, or if you want to work on what was already publicly decided in issues - You are welcome to just send Pull Requests! If you want to change rules, it’s better to first open a suggestion in Issues.

Some rules:

  • No text/code/graphical assets generated by GenAI/LLM software allowed.
  • Every file should have copyright and license indicated via REUSE headers.
    • If you are not sure, this can be done later, so just send changes as-is.

It’s recommended to work locally in a markdown editor (like Obsidian) or in any text editor with markdown syntax highlights (like Kate or Evi).

To test the static website locally, install mdBooks, run git clone https://codeberg.org/mailbun/touhou-dnd, and run mdbooks serve --open in project directory.
