HE HAS SPOKEN!!!
All kidding aside, the Discipline Skill+Feat requirment seems fine to me too, while I don't find the fatigue penalty suitable (I like Djiin's Recharge Time or a similar temporal limitation like "only once per encounter").
I know start converting the few Maneuvers I've done around these new specs and I'll post them ASAP.
If you guys posted some ideas for Manuvers with a Skill Requirments between 24-26 (the range of level where I'm playing, as my DM pointed out), I'd be very helpful.
What's this "Exalted" you guys are talking about?
