That's cool! Does it include people like Nishiki and Flannel though? Or are those special cases since that's a race thing?
Are beaststones/dragonstones buyable? I can imagine since we were shown Aqua literally creating a dragonstone that she could be a stone-seller.
EDIT: Also, the effects of the stones, like how we've been told that hidden weapons apply debuffs and steel weapons have a lower chance to double?
