This expansion of Bloodborne: The Card Game adds new challenges and elements to the game. Each Hunter can choose their own Caryll rune, which gives them unique powers and a new gameplay experience. Death by Death Tokens is a much greater threat to Hunters, as the more times a character dies, the more they limit the number of Trophies that can be obtained. And finally, this expansion adds all-new Monsters, Bosses, and Hunter Upgrades to the game. If you want a new kind of challenge, the Hunters' Nightmare is waiting for you.
