I'm not big into giving out massive details of what is contained herein as I never want to give away anything to folks who might end up meeting the nasties inside this PDF on the far end of a DM screen.
Suffice to say it is well written and has a clean, easy on the eyes layout. As I get older and my eyes get worse, this gets more and more important every year.
While it has some monsters and helpful tips from many voices, all are articulate and communicate well. I did find one minor proofing error, but it doesn't detract from the overall product.
I will say the Gravesbane Colossus is the single most bad-ass enemy I've read in a good 5 years, if not more. Extremely well done. It WILL inspire fear in your players.
