Oh, I'll start with the Shaolin ones; not sure where I go with them, as it comes to mind, training techniques may go in trees - without a certain base training, you can't do a more advanced one, after all.
Ideally, I'd like a mixture of soft and hard techniques, but I want to base them on stuff that has been rumored to exist, at least, at some point. Basically, no over-the-top anime or wuxia stuff. That's... more of a Mage than Mystic thing, on the Hero / Adventurer / Mage / Mystic scale, and Monk is definitely a Mystic type.
The idea for Grandmastery is synergy combos - for an example, if you have the poison hand and something that allows you to, say, use combat maneuvers at range, you could do poison hand hits at range, or if you have damage absorption training done and you take some internal manipulation style, you could throw opponent's attacks back at them.
Not sure what to do with Great Grandmastery yet.
