The Adventure card is a card that can be used in Eldritch Horror. Similar to a Mystery, an Adventure is a multi-level encounter that will take the player around the world to accomplish various tasks. The adventure will designate a location to place the Adventure token. The player is tasked to go to this place, usually resolve a test, spend Clues, Focus, or other Assets in order to advance the Adventure, much as they would for a Mystery. They will always give a type of benefit, sometimes advancing the active Mystery, granting Unique Assets or Artifacts.
Unlike a Mystery, an Adventure is not required to be completed to finish the game. Oftentimes, Adventures are started with a Prelude, in which the player uses the adventure listed on the card. However, players may choose to pick an adventure to start the game if they wish, particularly if they wish to use a side board without the subsequent Ancient One or Prelude in play.
