When delving into Curse of Strahd, you'll want to incorporate this tarroka deck, a 54-card adventure supplement produced by Gale Force Nine. Use the tarroka deck to randomize locations in the adventure, allowing Dungeon Masters to customize every party's exploration of Barovia, allowing Curse of Strahd to be replayed without backtracking for years to come.
Also included are the rules for Prophet's Gambit, a card game for 3-5 players.
