Eldritch Horror · Expansion

Signs of Carcosa

Depends on your group

Our take
Recommended as a small box if you skipped Under the Pyramids; BGG players warn its Impairment effects pile up unpleasantly when combined with that box.
What you need first
Just the base game
What it adds
Hastur as a new Ancient One, four investigators, new encounters for every continent, plus new Conditions, Spells, Assets, Artifacts and Mythos cards built around madness.
What it fixes
Freshens up every encounter deck with a madness theme without adding a side board.
