So apparently they have the stones in hand!
Here's them all with the base stones!
They actually have differing colors based on which version you use!
(I assume the Kitsune and Garou have the same color, so I only used the Garou since it's easier.)
This shows that time of day doesn't change the color. (Also it's the Beastrune.)
Here's the Beaststone +! It's a bit redder I think.
Finally, the Dragonstone +! It's more purple!
