Your physical endurance. Lost on physical challenges. If Stamina hits zero mid-floor, you are sent back to the floor shop with Stamina restored to half — but Strength and Dexterity checks are penalised for the rest of that floor.

If Stamina hits zero on Floor 1 (no shop): your run ends immediately.

If both Stamina and Sanity hit zero at the same time: your run ends with no score recorded.

Against the Warden: either stat reaching zero ends your run immediately.

Your mental fortitude. Lost on psychological challenges. If Sanity hits zero mid-floor, you are sent back to the floor shop with Sanity restored to half — but a random equipped item is lost.

If Sanity hits zero on Floor 1 (no shop): your run ends immediately.

Spend 1 Fate to reroll any die — once per roll, keep the new result. Fate tokens also let you reroll item modifiers at the Tinkerer. Some INT pass outcomes grant bonus Fate.

Each room offers three approaches: Strength, Intellect, or Dexterity. You roll a d20, add your stat, and compare to the difficulty. Higher stat = lower difficulty = less gold reward. Lower stat = harder check = more gold if you succeed. You always pass through rooms — failing just costs you resources.

Final score = Gold + (Stamina remaining × 2) + (Sanity remaining × 3). Conserving Sanity is especially valuable.
