Hey Mr. Padfoote, just wanted to let you know that as I was doing some googling trying to find reasons why my ritual diviner isn't working, I came across a beginner's guide to Blood Magic that... well... they ripped you off, and I didn't see your name quoted.
Here's a link to it:

Hope they asked you.
I was actually the one to put that there at the request of @SatanicSanta back when this was first written.
Thanks for bringing that up though, I appreciate people giving me a heads up for things like this.
