Build a five-room dungeon in one click: a guarded entrance, a puzzle, a setback, a boss fight and a reward — stocked with SRD monsters and treasure for your party.

How a five-room dungeon works

A short adventure site with five beats, each doing a different job. Rooms can be caves, decks of a ship or wings of a mansion — the beats are what matter.

  1. Entrance and guardian. Something explains why nobody has looted the place yet, and the session starts with action.
  2. Puzzle or roleplaying challenge. A problem swords can’t solve, with more than one way through and a hint planted in room one.
  3. Trick or setback. Tension: a false prize, a trap, a betrayal or a fight that drains resources before the finale.
  4. Climax. The big fight, with terrain and a twist that make it memorable.
  5. Reward and revelation. Treasure, plus a discovery that points to what comes next.

Fights use the 2024 XP budgets: the guardian is a Low fight, the climax Moderate or High. Monsters and magic items come from the free SRD in our compendium — send any fight to the initiative tracker with one tap. Room text is written by Roleplayer; reroll any room you don’t like.
