@Happerry, while you're here, could you please point out any issues in my plan?
No active conflicts between your sources noted by eyeballing your plan.,
How does Cauldron of Creation 4 and Oncoming Monsoon 4 combine?
Fairly well. They don't have any blatantly obvious combo techniques, but they don't conflict either, and Cauldron's high energy stores helps feed the brute force and windstorms of Monsoon style. It'd be less a combination of making what you have stronger and more just letting you use it longer and more freely without having to worry about supply issues. Which is useful enough in and of itself if someone swarms you with minions or is a Cobra master type dude.
Shadow Typhoon - Strong in subtlety in that you can fight to your maximum ability in the public without exposing your identity as a martial artist.
Noooot so much. This is the only blatantly wrong thing, so have a correction and history lesson.
Shadow Typhoon style is basically ninjutsu, minus naruto style magic and illusions. It migrated over to the mainland when a clan of ninja decide fantasy japan land was getting to hot for them to handle and, well, evacuated to the mainland. There they ended up interacting with Kung Fu dudes as the local martial artists, stole some secrets, lost some to rivals and enemies and friends, traded other secrets for shiny Kung Fu secrets, and basically cross pollination happened.
Several hundred years later the style has been spread around more and adapted to the needs of the world of Kung Fu. It's better at fighting then an actual Ninja, and a lot better in a fair fight then an old style ninja, but in return has lost a lot of the advanced espionage and poison secrets because there's a lot less call for ninja mercenary type missions. Or in short, they kept getting into Kung Fu fights and no one was hiring them as spies and assassins, so they got better at Kung Fu Fights, and cheating at Kung Fu Fights, and worse at the stuff they weren't finding useful.
If you fight in public with it, you'll definitely be showing off your martial artist skills. (Of course, no proper Shadow Typhoon user would try to get in a public fight anyway. Sneak attacks in the middle of the night work much better.)
Anyway, even if its lost a lot of the spying and general covert affair knowledge from lack of use, it's still better in those areas then 80% of the other Kung Fu styles because those styles don't teach that kind of thing, like, at all. Imperial Dragons are not given to being subtle, and neither are the firestorms a Blazing Furnace grandmaster can kick off. And so on.
If you want to fight in public without showing off martial artist skill, Weapon Mastery is the choice to take, and is what most nobles and soldiers use. As well as the bandits.
How about just asking the QM instead of arguing what we think they meant?
@Happerry Clarification on Tyrant Sword please?
Tyrant Sword is, from most to least effective, best verses swords, decent verses most barehanded fighters, average verses other weapons/sword using schools that also carry the anti sword trait, and bad against other weapon or barehanded schools that have the anti sword trait.
Also note that a lot of styles still use swords even if swords aren't specifically called out for them. Or spears. Or other weapons.
Generally speaking, if a style isn't called out as being barehanded only, you can assume the user is going to be using some sort of weapon simply because weapons are better then barehanded combat. That's why people use swords or spears or maces or axes in the first place, they're more deadly then someone's hands.
Now, sure, a master's hands can be just as deadly as a sword... or that master could just pick up a sword and use all that skill that lets him be equal to a sword to be even more deadly.
Howling Devil Dog users tend for short heavy blades they can use inside the cramp corridors of ships, Crane and Spider stylists go for spears a lot to combine their mobility advantage with a reach advantage, Thousand Slayers are usually weapon experts of some kind, Raging Furnace users enjoy using their style to gain the flaming weapon bonus (among other things, it's a lot easier to heat a sword blade up without damaging yourself then to make your fists red hot without cooking your own hands off), and so on.
Also swords are like the most commonly used weapon by J Random Noble as well.
