I devised a conversion table for mapping *W stats to 1d100 (for systems that use percentile skill scores, etc). That post is below. But rather than focus on this one particular mapping, I have decided to open up a conversation on ALL sorts of probability maps or stat conversions that can be used to hybridize two game systems.
Are you a mechanics packrat who loves using tables and charts from one system while running another? Show us some of your mojo!
