The Branch & Claw expansion for Spirit Island includes two new Ghosts (Sharp Fangs Behind the Leaves and Keeper of the Forbidden Wilds) and a new opponent (France), as well as adding events to the Invasion phase of the game!

The event deck contains events that occur every turn and adds extra variety to the gameplay. In addition, the expansion includes tokens that prevent invaders from exploring, building, or plundering, or adds wild beasts to the land. There's also a new set of powers that take advantage of the new tokens and expand the gameplay, 15 new fear cards, new destruction cards and new scenarios.
