Here is a one-page PDF of the Roll to Advance system I introduced last week. Obviously, the one-page format does not allow for in-depth explanation or discussion of the system, but it does provide the basics needed to use it in play.
This PDF currently uses the original racial modifiers despite the fact that I still suspect that they may be slightly too high.
A number of readers have expressed interest in trying this in their games. I would LOVE to hear feedback from those that do, particularly about adjustments that you’ve made and your experiences with the multi-class methods.
