When sigilprep.com went live 10 years ago, it was based in the 3rd edition of D&D (or the 3.5 edition, if you prefer). The anchor of the entire website was presenting the character classes as courses available at the school. I later changed it to 4th edition, before letting it die.
This time around, we’re tagging every edition. Even the little pamphlet version that started it all.
Nothing is added to this document since the first upload, but I made some layout changes. Enjoy.
