OSR: 1d1000 Mutations

I've created a PDF of my 1d500 Biological and 1d500 Supernatural mutations. About a quarter of them were significantly edited, rewritten, or replaced. Most purely mental mutations are gone. Others were revised based on playtesting. Some are minor, some are major, and a rare few are deadly. All, I hope, are interesting.

PDF

The PDF also a condensed mutation table, guidance on applying mutations, and a few other useful tips. It's the biggest mutation table... in the world. Not really.
With thanks to:

Elf Maids & Octopi (indexed here).
Scrap Princess (Monster Manual Sewn From Pants) (table 1 and 2)

Arnold Kemp (Goblin Punch)

Arnold's post covers why mutations are great. This list is also suitable for creating degenerate quarter-lings for Ultraviolet Grasslands or the effects of thaumic fallout from Magical Industrial Revolution.If you like this sort of thing, try Red Box Vancouver's The Metamorphica. More mutations!
