Hm. That is the kinda theme I have going for the class. Might go with this.
I like Adept. Though, it might just be because I love Golden Sun but it makes me think more of a mage like class. I might just spin that into it's own class.Adept
I'm one of the ones who'd be miss pronouncing it. Actually had to google how to say it."Physical Adept," perhaps, to convey someone's who's ability comes from a deep mastery of their own body?
Otherwise, I second Xia/Wuxia/Youxia for a Chinese vibe. You will, of course, have to deal with correcting players who want to pronounce it "Wucksia", but that's a small price.
