I wonder if it's possible to learn how to get your own Quasi-Mech suit from Kazuo. Maybe do enough quests for him and he'll teach you how to make a prototype of your own, and encourage you to use it frequently against the various beasties of the Frostmarches. I figured it would grant you a lot of defensive buffs, but comes with some drawbacks like being a once-per-battle ability, so you can lose it if you get stunned/proned, maybe a Thunder Weakness too. But still, magitech wood mecha would be awesome to have.
