Branch and Claw
The Event Deck adds a new form of randomness to bring extra variety into the game. One Event Card is resolved per Invader Phase, each with both beneficial and detrimental effects for the Spirits. In addition, this expansion has Tokens that prevent the invaders from Exploring, Building, or Ravaging, and a token to represent the wild Beasts on the island. There's a new set of Powers that use these new tokens and expand the gameplay, new Fear cards, new Blight cards, and new Scenarios.
Branch and Claw was released as stretch goals in the original Kickstarter in October 2015. There was a $60K goal for the Event deck and additional Power Cards that utilize the four Spirit Tokens introduced in this expansion, a $75k goal to include four scenarios, and an $80K goal to add the two additional spirits, Sharp Fangs Behind the Leaves and Keeper of the Forbidden Wilds, both of whom make use of the new tokens.
