Something I haven't been able to find anywhere so far, is classes seem to have some hidden moves, not listed in their movset (which isn't surprising). The Warden, Conqueror, and Kensei (and probably most or all the others) have a move when you hit both the light and heavy attack at the same time. I haven't experimented with them in actual combat, so I'm not sure on their potential, but they seems to use a lot of stamina.
Could there be more? Does anybody know of anything else that's not listed in the movesets?
