I don't get the fact about how you need Shield Stand skill for Smash skill when you can't even use shield while having 2 handed swords (btw I'm pretty sure Smash is supposed to be for 2 handed because it's prequisite is Shield Stand and the Shield Stand's prequisite is 2 hand mastery)
but maybe I just don't get it because Shield Stand description says when you use it you throw a flaming shuriken
