Does this have anything more then the 3 class and 1 supplement pdfs they released earlier or is it just a compilation of those?
It has 2 new Maneuver Disciplines, Black Seraph and Silver Crane. The former is a fiend/hellish-inspired school that focuses on sickening opponents, aggressive mobile charges, and unholy power. Silver Crane focuses on strikes which can heal allies within range, light-based attacks, and some attacks which can shut down/hit incorporeal and possessing enemies.
There's also archetypes for psionic characters and a new prestige class, the Awakended Blade. It's a martial/psionic gish. Other than that I haven't spotted anything else yet.
Expect the first part of my Path of War review tomorrow, if conditions/Internet connectivity's ideal.
