As the enigmatic secrets of the Mythos begin to unfold, it takes a keen mind like Carolyn Fern’s to help piece everything together. With her intellect and deep understanding of the human mind, Carolyn can heal horror from her fellow investigators while cracking mysteries of the unknown. This Investigator Deck for Arkham Horror: The Card Game comes with a pre-built, ready-to-play Seeker deck, allowing you to jump into a campaign from the moment you open the box. Also included are additional cards for upgrading the deck during a campaign. Not a standalone expansion. A copy of the Arkham Horror: The Card Game core set is required to play.
