I've been working on a 1e pathfinder book, about the size of a player companion and it is nearing completion. However, I'm trying to add the OGL and I'm unsure of what exactly it needs to include.
If I so much as mention a Paizo feat as a requirement for one of mine, do I need to add the source product to the OGL? For example, if I had a feat called pummeling master class that requires pummeling style, do I need to cite the book pummeling style is from in the OGL?
Also, is there an easy way to add the OGL for any products your referencing? I saw there was a generator online, but it doesn't have all the books I might need depending on how the above statement works and it doesn't seem to work in general anymore.
