The Metamorphica, Revised Edition
A system-agnostic resource for generating biological, psychic, and supernatural mutations in dark fantasy, horror, science fiction, superhero, post-apocalyptic, and other campaigns. It includes more than 700 mutations, random tables, and procedures for creating aliens, demons, monsters, mutant animals, humans, and plants. Additional tables generate strange devices and magic items, while the revised edition reorganizes the material, updates existing mutations, and adds new tables for campaign-specific details.
