Some overhaul after quite a bit of discussion and experience with Forbidden schools.
-Forbidden Cost is now standardized, each Forbidden school inflicts Forbidden Price equal to the maneuver/stance's level, penalties are measured based on your current Forbidden Price, depending on its Forbidden Cost.
-Sky Ruin, Corpse Voyage and Marvelous Mt. Ooe no longer inflict penalties on saves. Instead you lose HP when you need to roll one of those saves, more if you actually fail.
