Questions about the Monster Book in other versions.

Mu Lung Dojo. Those bosses, sadly, do not drop cards. Except the last boss there.

Yeah, the Mu Lung Dojo. That's too bad they don't drop cards.

On Topic: I really don't think the Monster Book is held very highly in GMS, it seems almost hidden from other players, the only reason why I would check someone's progress on their book is if they told me "I have x cards". (I thought that was a random smile i just noticed, haha)
