One Deck Dungeon

One Deck Dungeon is a dungeon-crawling adventure game for one or two players, built around a deck of cards and a handful of dice. Choose one or two heroes, explore a dungeon, roll dice to overcome encounters and fight your way toward its boss. Once you know the game, a session takes about 15 minutes.

Heroes and progression

Choose from six heroes: Mage, Warrior, Rogue, Archer, Paladin and Mist, a breach mage from the world of Aeon's End who helps defend Mynerva. Each has a different role, from solving problems with spells to shielding allies from danger. After each game, your heroes progress toward unlocking up to 15 talents that strengthen them in future games.

Dungeons and challenges

The game includes five dungeons, each with its own dangers and boss:

• Dragon’s Cave: face a thick-skinned wyvern that prefers its heroes crispy.
• Yeti’s Cavern: survive freezing winds and biting cold before confronting an abominable snowman.
• Hydra’s Reef: fight a regenerating, venomous hydra that grows another head when one is cut off.
• Lich’s Tomb: contend with undead foes, evil curses and magical wards.
• Minotaur’s Maze: enter a maze with little hope of escape.

Encounters and dice

Encounter cards contain colored boxes that you try to fill with your dice rolls. Any boxes left unfilled bring costs in hearts and time. Overcoming encounters can also earn rewards, such as skills, stat improvements or experience.

Expansions

The Forest of Shadows expansion adds adventures in forest areas and mossy underground tunnels. It includes five heroes—Alchemist, Druid, Hunter, Slayer and Warden—and five dungeons: Lair of Indrax, The Mudlands, Realm of Venom, Smoldering Ruins and The Vile Roots. It also adds a 44-card encounter deck, along with progression focuses, basic skills, potions and more.

The Abyssal Depths expansion adds six Fiends that pursue you throughout your quest to reach the boss, each with two difficulty levels, as well as two aquatic heroes.

Relics of the Forge adds six heroes—Flamberge, Foxfire, Shade, Smith, Spinner and Thrasher—and five dungeons: Arena of Fire, The Armory, Chasm of Soot, Heart of the Forge and Tropic of Lava. It also contains 12 relics with unique abilities and mechanics, a 44-card encounter deck, and additional progression focuses, basic skills, potions and more.

Individual additions include three heroes—Caliana, a faerie; Fanatic, a Sentinel who smites evil; and Witch, whose chaotic magic hammer can smash oozes—and two dungeons: Cinder Plains, where a Hellhound awaits, and Phoenix's Den, which challenges heroes to withstand the heat.
