I'm still trucking away at the Tau, and while working on the Kroot warscroll I remembered that there used to be a full Kroot army list. While I didn't dive down that rabbit hole, I did create a hero warscroll for the Master Shaper to make the Kroot army an option.
After poring through the fluff and unit entries, I ended up making two more Kroot warscrolls, one for Kroot Carnivores that includes Krootox as a unit upgrade, and one for Kroot Hounds. I considered breaking out Krootox into their own warscroll, but they didn't seem like they really stood on their own. Anyhow, here they are.
