White Wolf's seventeenth expansion for Vampire: The Eternal Struggle is Heirs to the Blood, which focuses on the bloodlines and infernalists. Each booster pack contains 11 cards randomly selected from a set of 168 all-new cards consisting of 54 rares, 58 vampires, and 56 commons. The set also features 4 non-random preconstructed decks: Gargoyle, Kiasyd, Salubri antitribu and Samedi, which contain even more cards and are designed to get beginning players started right away. All the new cards in the preconstructed decks are also found in the boosters, and naturally each preconstructed deck contains reprints of vampires and library cards from earlier sets. New Stuff Research Area: Some cards may move cards to a special staging area called the research area. The cards in your research area are face down and out of play; they can be affected only by cards and effects that say so explicitly.
