This generator aims to help Game Masters come up with unique creatures. Use these results as a starting skeleton and flesh them out with your own descriptions and lore. Put your completed monsters in the comments so we can all enjoy them!
You can contribute to the generator by adding to this document (or simply look at all the cool options).
Thanks to Curio Solus for inspiring this idea and doing the bulk of the work. Christopher P. Wolf for the code that inspired these generators. And to the OSR community and Knave community for being such an encouraging, welcoming place. Monster Image from “Historisches Festbuch zur Basler Vereinigungsfeier, 1892”
