So I have played a few games, I have really begun to have fun with PFS. The more I learn about Pathfinder, the more I am encouraged to keep playing and learning more. I am enjoying this RPG. However, each time I learn something I am finding that my previous choices/decisions/purchases may not have been the most correct, or in some cases were illegal in PFS.
For instance: I purchased a Masterwork Quarterstaff after my first game -> what I now know is an illegal purchase. The Quarterstaff is a double weapon. "The masterwork quality adds 300 gp to the cost of a normal weapon. Adding the masterwork quality to a double weapon costs twice the normal increase (+600 gp)." - Ultimate Equiptment, Paizo 2012.
This After my first game I earned 2PP/Fame; to spend over 500gp, I needed 9PP/Fame.
This cost me 600gp, this was well out of my purchase range for a Fame of 2. I believe this purchase was illegal, Should I remove this and other illegal purchases I made in the past or continue using it since I now have 10PP/Fame?
