Arkham Horror LCG: Core Set vs Investigator Decks – Start Here

Quick answer

Start with the Arkham Horror LCG Core Set if you want the full campaign experience and rulebook. Pick an Investigator Deck like Carolyn Fern's or Marie Lambeau's if you already own the Core Set and want a ready-to-play new character.

What the Core Set gives you that decks don't

The Arkham Horror LCG Core Set is the foundation of the game. It includes the rules, tokens, scenario cards for a full introductory campaign, and a set of basic investigator cards. Without it, you cannot play the game at all. Investigator Decks are expansions that require the Core Set to function; they provide a pre-built deck for a specific character but no scenarios or rulebook.

When an Investigator Deck is the smarter buy

If you already have the Core Set and want a new investigator without the effort of deck-building, a ready-to-play deck like Carolyn Fern's Seeker deck or Marie Lambeau's Mystic deck saves time. Each comes with a complete 30-card deck that is balanced for the game's difficulty curve. This is especially helpful if you want to jump straight into a campaign with a different playstyle.

Decision rules

• You have nothing yet: Buy the Arkham Horror LCG Core Set first. It is the only product that contains the rules, scenario cards, and tokens needed to play. Investigator Decks cannot be used without it.
• You own the Core Set and want a new investigator: Choose an Investigator Deck. Carolyn Fern (Seeker) excels at investigation and support; Marie Lambeau (Mystic) offers a unique resource-from-horror mechanic. Both are ready to play out of the box.
• You want to try a different class without deck-building: Pick the Investigator Deck for the class you want to explore. Seeker (Carolyn Fern) focuses on clue-gathering, while Mystic (Marie Lambeau) leans into spellcasting and resource manipulation. Each deck is balanced for immediate play.
