One Deck Dungeon

To set up One Deck Dungeon, choose one of five hero classes and take their character card. Select a dungeon, placing its specific rules on your turn reference card with one white potion cube. Arrange your level cards from one to four, place the stairs card, and shuffle the encounter deck face down on top of it. Keep your dice pool nearby.

The main objective is to navigate three dungeon floors of increasing difficulty, gather loot and experience to level up your hero, and ultimately defeat the dungeon's boss to claim victory.

Each turn begins by discarding two cards from the encounter deck to represent the passage of time. Then, you may explore by drawing and placing up to four room cards, and choose to enter a room, facing either a combat encounter or a peril. Roll your dice pool based on your hero stats, apply skills and potions, and fill challenge boxes to overcome the encounter.

Scoring and progression are tracked using the campaign pad. After each game, record your results, checked boxes for gained levels, floor descents, and boss defeats to unlock permanent talents for future playthroughs.

The game ends in victory if you successfully defeat the final boss on the third floor. It ends in defeat if your hero loses all their health hearts or if time runs out and you cannot sustain further hourglass penalties.
