Amethyst: Evolution
A roleplaying game sourcebook set in a near-future world where magic and technology remain in conflict amid threats to both. It introduces three new races, revised versions of existing races, fourteen lifepaths, and the vanguard class, along with new powers and class features for the original classes. The book also includes eight simplified essential classes, more than thirty paragon paths, over one hundred feats, twelve epic destinies, and equipment ranging from aircraft and mecha to nuclear weapons. The material supports campaigns in the established setting or in other homebrew worlds.
