The Night Cage: The Endbringer promo

The Endbringer - Boss Monster - A new boss that speeds up the end game by causing tiles to be discarded on each player's turn. After 5 Omens are drawn, the Endbringer sits on top of the draw deck. At the end of each player's turn, discard a tile from the Draw stack. This effect continues until the Final Flickers begins. If playing within the Dirge, use the 5 Omens as both Boss Monsters. Given out at Gen Con 2021 and in Game Trade Magazine # 260 and included in the deluxe edition of The Night Cage: Shrieking Hollow.
