Reduction 7... but no bonuses to Armor TN from Armor. A Spider Bushi can wear heavy armor, stack kiho, AND stack his school bonuses to get Reduction well over that. Indeed, that's what I intend to do with Daichi in the Harvest game, hah. But yeah, literally acetic, meanings distinct lack of extra gear. Though I'm tempted to try and get a no-dachi as it seems like a fun guy, swinging around a massive sword in basic clothes.
Also, each ronin 'technique' is technique a seperate path and group. Using one is just saying you learned from the others OR have a technique that just happens to be the same. In a way, it's like Mugen making up his random style, just made it up as he went along. Many holes, but crazy enough to work.
That said, there are two other ideas... one I think that would work hilarious with the party. A Daidoji Scout, from Great Clans, or a Tsuruchi Bounty Hunter, likely working with or even AGAINST the magistrate and trying to chase down the ronin. Would be a very interesting party.
Still love the Taoist Swordsman though.
