Humblebird's Infinite Monsters


“A living ribbon of water rises from the deep, draped in seaweed. It asks if you know any students who need a math tutor.”

Humblebird's Infinite Monsters is a high-concept monster generator with an emphasis on behavior: what the monster does, and how it relates to the rest of the world. Choose from a dozen or more answers to questions including:

  • Where does the monster live?
  • Why does the monster exist?
  • What drives the monster to do what it does?
  • How does the monster spend its time?

Humblebird’s Infinite Monsters is a monster generator and not a bestiary. Because of its scope it requires the user to fill in the details, including any mechanics, and can't be used to generate monsters on the fly. Instead, use it to generate your own bestiary ahead of time, as well as iterate on existing bestiaries and monsters.


  • System and setting agnostic
  • Supplements other monster generators and bestiaries
  • Suggestions for generating monsters for different genres
  • Internal links for convenient navigation between table of contents, trait tables, and trait descriptions
  • Spooky monster art by Bowelfly

This is a very thorough monster generator. There is so much detail written and so many things to roll for. Great for generating monsers for a tabletop adventure or for art prompts even! [...]

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
