Dungeon Writing Guide

A simple Dungeon Master guide for writing clear dungeon stories and playable events.

Core Philosophy

Dungeon events should be simple, playable moments that are easy for a DM to run without extra interpretation. Each event should present one clear situation for the players, such as a discovery, obstacle, creature encounter, or magical interaction.

Focus on what the players can do immediately. Keep events magical and imaginative, but also clear, grounded, and easy to understand at the table.

  • Use at most one named NPC or creature to interact with in each event.
  • Groups of simple monsters are fine when the scene needs a battle.
  • Avoid complex politics, multiple factions, competing goals, and confusing setups.

Dungeon Idea

Start with one simple, clear idea that fits the current campaign and continues the story naturally. The best dungeon ideas are easy to explain in one or two sentences and point toward one main problem, mystery, or threat.

Dungeon Summary

Write the dungeon as a sequence of 5 simple events that flow from beginning to end. Keep the story easy to follow with a natural progression and avoid extra storylines.

Example Format

Event 1

The party arrives at the dungeon entrance and learns the first clear problem.

Event 2

The heroes face a simple obstacle, trap, or locked path that slows them down.

Event 3

They meet a creature, guardian, or magical scene that creates a clear choice.

Event 4

The group uncovers a secret, treasure, or clue that leads to the final area.

Event 5

The adventure ends with a final challenge, discovery, or satisfying resolution.

Event Writing

Each event should focus on one main action or problem. The goal is to create scenes that are easy to run, easy to understand, and immediately useful at the table.

  • Keep each event simple and playable, focused on what is happening right now.
  • The read-aloud text should describe the scene as the players arrive without revealing hidden traps, enemies, or outcomes.
  • The details section should help the DM run the scene clearly and quickly.
  • If a character or creature speaks, include a short quote the DM can read aloud.
  • Include 2-3 skill checks per event and use Perception or Stealth when one side is hidden.
  • If a trap is present, include level-appropriate damage as the failure effect.
  • Most battles should include a skill-based alternative to avoid or resolve the fight.
  • Use classic fantasy monsters that are easy to understand and easy to run.
  • Keep each event focused on one main idea or action without side plots or extra layers.

Conclusion

Wrap up the dungeon in a simple and satisfying way. Give the players a chance to rest, return home, or trade and sell their loot when it fits the story.

End the adventure with a clear sense of completion, then level up the party with a short celebratory line:

“Congratulations, you are now Level X!”
