Taigha artwork?

Good to know ;).
I didn't see them in the GenCon video, but as you said, they're on the cover of the box .

 

The GenCon video is where the art and renders in the thread come from :)

 

They look smaller than S2 but I think still a bit bigger than S1.

 

You certainly wouldn't. Best to keep beasts like these under control and not run rampant.
