From the introduction: What follows is are additional rules that shall be used in addition to the 'core' Risus, the Anything RPG rules by S. John Ross. A copy of the Risus rules are needed to play. Why? I wanted a little more fantasy flavor and 'feel' to my Risus game, I found a few fan created things that I liked, but just didn't fit perfect, so like any other GM I decided to write this and call it mine.
