  1. I feel like this could have a list of Advantages that enhance skills and what they enhance. Right now it feels a little barebones and not very helpful when you're looking for the tchy little bonuses lying around.

    1. I thought about that but think that is too much info to put up here. Its in various books and I am concerned about putting more than a page reference so as to not violate copyright.
