I made this custom adventure for the Mythos CCG a while ago but forgot to share it. The adventure card allows the player to replicate the H.P. Lovecraft story "The Dreams in the Witch-House".
The best CCG ever. Ever.
I computed the Adventure Points for this using The Art of Playing Mythos Book. Computing AP using these guidelines requires some interpretation and it's possible that more AP, up to +15, might be warranted for this one since it requires some hard-to-play cards.
EDIT: Oops… looks like I have shared this before, back in 2014! Time flies.
