From publisher blurb:
Sometimes it is not what you can do, but what you CANNOT do, that makes your character interesting.
With martial drawbacks, you can customize your martial spheres, gaining bonus talents and interesting hinderences to make your character more closely resemble what you want. With over 25 different martial drawbacks, there's something for everyone.
Made for Pathfinder 1st edition and the Spheres of Might system.
