Islebound: Emerald Edition is a special edition of the game with modified components and rules. This edition removes the book as a resource from the original game and replaces it with emeralds. Emeralds have a different use than books. You collect them when you visit a city owned by another player and when you conquer a city.

Emeralds must be used to purchase building cards and can also be used to perform special abilities, such as keeping pirates and serpents after a battle!

The building deck has been revised to account for this resource change. It includes modified building cards from the original game and some from the Metropolis expansion. There will be no building card expansion for Islebound: Emerald Edition, and the Metropolis expansion is not compatible with this edition.
