I think mutations are better handled by putting them in a post apocalyptic setting book.takyris said:Would "mutation" just be a new race, covered under the backgrounds section (mind you, this is based on one readthrough -- I'm by no means an expert)? I'm speaking of birth mutations, of course, not "Radioactivity has made me grow gills!" mutations, which would best be handled via talents.
Such as the True20 version of the Darwin's World Survivor's Handbook (which came out fairly recently).
