The Metamorphica: A Book of Random Mutation Tables

UPDATE: A new, revised version of The Metamorphica

is in the works and will be available soon.

See the new blog post HERE.

As promised, the book is finally done!

This is a picture of the cover.

The Metamorphica is a very large system-agnostic collection of random mutation tables, for any table-top role-playing game. The digest-sized PAPERBACK VERSION is available from for only US$6.66 plus shipping, but you can download the pdf version for free (either FROM LULU or FROM HERE for less hassle) from DriveThruRPG HERE.

How did this happen? Good question!

I was originally inspired to make this when I started using the old Realm of Chaos mutation tables while I was running old Red Box D&D. We had a lot of fun with mutagenic substances so I decided to make a much larger collection that included mutation ideas from a whole range of other role-playing games. Along the way I added a lot of new ones as well, and when it became too big to be a stapled booklet, I decided to add procedures for creating all sorts of monsters and mutants. And also to make it available as a printed book and not just a pdf.

The Metamorphica is system-agnostic, meaning there aren’t any rules in it per se: no attack bonuses, no hit points, and no task or conflict resolution systems. I intend to use this for more than just D&D, but making the book compatible with such disparate systems as Metamorphosis Alpha, Burning Wheel, Apocalypse World, and Diaspora would make it way too long, and take way too much time. You can just make up rules in play if you need them, that’s what I do. It’s really not that hard.

Art preview!

The Metamorphica was written by Johnstone Metzger and illustrated by Andrew Gillis, Nathan Jones, Johnstone Metzger, and Nathan Orlando Wilson. If you need to get in touch with anyone about this book, Red Box Vancouver (no spaces) has a standard gmail address that will accept your inquiries.

Also? It’s free!

Yes, this is (essentially) a free book. But if you would like to not-so-subtly encourage future products of a similar nature, or just buy me and/or the artists a drink by way of thanks, feel free to donate whatever you feel is appropriate. I will also happily accept pdfs, which you can send to the above-mentioned gmail address (the name of this blog, no spaces).

Or, if you would really like to do me a favour (warning, real-life bummer stuff follows):
I find the violence surrounding coltan mining in the Democratic Republic of Congo, and the economics of the electronics industry that encourage it, particularly concerning. Especially since this book would not have been possible without such electronics. However, I have neither the time nor the expertise to track down and properly vet charitable organizations working to solve this issue. If you know of one, and can make an adequate case as to their accountability and their work in the DRC, please let me know. If you don’t know any charities working in this area specifically, don’t worry about it, just enjoy the book. And if you are unaware of this issue, please look it up, the information is readily available. Thank you.

  1. As a huge fan of mutation tables, I must say that the one provided in this book is the best I’ve ever seen! It’s not absolutely comprehensive, but it’s much , much, much more so than any other I’ve read, and I’ve pretty much read them all!
