How can I get werewolf paintings?

Question

They do not seem to be a quest reward from the new grimvale extension and there is no mini boss with this update. Where can we get these pieces?

Answer 1

In the place where you tame the foxmouse there is also a chest(in the north of the cave) that can be opened every 20h but you can only access with the Moonlight Ipomea's Stamen, this flower only appear during full moon
