Do you add the new mask monsters from the expansions into the monster cup when using Nyarlathotep, or do you just use the ones from the base game? I've been running it the second way; I wasn't sure if I was suppose to add the new additions.

You are doing it correctly. As the new expansion monsters increase the size of the cup, you need to add Narly's expansion monsters to maintain their relevance.

I'm kind of confused. The way I'm playing is that I have all the new expansion monsters, but I am not adding in the new mask monsters, 'cause I'm not sure if they are supposed to be added with Narly. However, it sounds to me like you're saying I should add them to maintain their relevance, which makes sense when I think about it.

Yes. Add them. How else were you thinking of using them? Or were they just going to sit in the box, looking pretty?
