Go for it! I'm glad to see the Silver Key class actually put to good use, it's not a famously powerful PrC so it's nice to see a case where it actually is powerful!

As an aside, how are you liking your game so far @chaincomplex? If I remember the OP for the recruitment thread, you wanted to get back to 3.5 and use this little PbP to tame GMing again. How is that happening so far?
