The Five Room Dungeon is a classic TTRPG design framework popularized by Johnn Four. It’s designed to provide a complete, narratively satisfying adventure in a single session by moving players through five distinct "beats" or rooms.

The Five Room Structure

• Room 1: Entrance and Guardian
  This room sets the mood and provides the first challenge. The "guardian" doesn't have to be a monster; it could be a literal guard, a magical seal, or a physical barrier like a cliff. Its purpose is to signal that the adventure has begun and to test the party's readiness.
• Room 2: Puzzle or Roleplaying Challenge
  After the initial combat or obstacle, this room changes the pace. Players might need to solve a mechanical puzzle, negotiate with a neutral NPC, or find a hidden path. It often provides backstory or foreshadows the final conflict.
• Room 3: Trick or Setback
  This is the "darkest before the dawn" moment. It weakens the party or complicates their goal—perhaps they fall into a trap, find their "shortcut" is blocked, or realize the villain is one step ahead. It raises the stakes for the upcoming climax.
• Room 4: Climax, Big Battle, or Conflict
  The main event. This room features the "boss" and the most complex encounter of the dungeon. It should be challenging and tie together the themes introduced earlier.
• Room 5: Reward, Revelation, or Twist
  The final room provides the "loot," but more importantly, it provides narrative closure or a hook for the next adventure. The party might find the treasure they sought, but with a twist—like a letter revealing their quest-giver was a traitor.

Example Layout: The Sunken Vault

Room	Type	Description
1	Guardian	A rusted iron golem stands before the heavy stone doors, demanding a password lost to time.
2	Puzzle	A flooded chamber where players must align mirrors to reflect light onto a specific crystal to drain the water.
3	Setback	As the water drains, it triggers a trap that locks the doors and releases a swarm of venomous eels.
4	Climax	A ritual chamber where a rogue priest is attempting to siphon power from an ancient artifact.
5	Reward	The artifact is recovered, but it speaks to the players, warning them of a greater threat approaching.

Design Tips

• Don't be literal: A "room" can be a clearing in a forest, a street corner, or a floor in a tower.
• Use loops: For a more engaging map, connect non-adjacent rooms (e.g., a secret tunnel from Room 2 to Room 4) to allow for non-linear exploration.
• Add "The Three Ts": Incorporate Timers (rising lava), Threats (monsters), and Treats (healing potions) to keep momentum high
