Trying to find information on the Sanity System from Horror Adventures. I read, I think, all the info on the PRD, but what I couldn't find was how often I should throw sanity checks or how many sanity checks I should throw at the party daily.
Anyone know where I can find this info, or can anyone point me to where I can find it? Is it just not OGL, and I need to buy the book for that particular tidbit?
Thanks in advance!
