We are well aware that Kickstarter Backers are always excited about bonuses! As a thank you for backing the campaign on Kickstarter, all Adventurer Pledge Level backers will also receive the Kickstarter Kit, for free! The Kickstarter Kit includes the Beer Goat, a summonable buddy you can take into the dungeon, complete with a miniature and item card. Throughout the campaign Stretch Goals will add more content to the Kickstarter Kit.
Stretch Goals have unlocked more content for the kit, including Solo Mode with the Beer Goat as your companion, and a mysterious new mini. These mysterious minis are important foes you'll face in the campaign, and revealing who they are would spoil the narrative. The silhouette for the mystery mini is a stand-in and does not represent the newly unlocked content.
Finally, content in the Kickstarter Kit will not be available in the retail version of the game.
