The Big Book of Madness (2015) is a cooperative board game by designer Maxime Rambourg, which pits 2-5 student magicians against the monsters escaping from the eponymous Big Book. Each player takes on the role of a student, each with unique powers and abilities. Players must turn the pages of the book, defeat the curses within, and eventually shut the tome for all time, all before succumbing to madness. Players use deck building to create a deck of elemental cards, spending these elements to buy new, more powerful spells, or to support their fellow students. For without cooperation between the players, all is lost.

Iello has announced the first expansion for this well received game, The Big Book of Madness: The Vth Element. This expansion includes 2 new modules, Dark Matter and Phobias. Dark Matter adds Dark Curses, the Dark Book, Dark Monsters and new characters to the game. Phobias adds new Phobia Cards, which are madness cards with permanent effects.

The Big Book of Madness: The Vth Element should be available in stores in February of 2020.
