Sketch a complete five-room delve with a seeded map, a motif, keyed challenges, and a revelation in the last room. Set level and party size for treasure and encounter hints, then share a seed to reproduce the same map and rooms.
It is a DM planning pattern: entrance and guardian, puzzle or roleplay, setback, climax, and reward with a reveal. The Dungeon Master's Guide does not define the label, but the beats match classic dungeon pacing for a single session delve.
Dungeon level sets Challenge Rating hints for guardian and climax rooms and rolls one DMG hoard summary for the reward room. Party size is passed to encounter math when compendium monsters are available.
Yes. Keep the seed, motif, and level the same. The map and the five room texts come from that seed. Motif, level, and seed sync to the URL. Reroll room changes only that room's text. The map stays with the base seed.
