The Salt Chapel D&D 5e One-Shot Mystery Adventure (Level 2, 4 Players)

One room, one keeper, and a blessing every caravan takes before the empty stretch east. The floor is inlaid with salt in a pattern the masons built around rather than over, because it was already here when they raised the walls. The guestbook records blessings from ninety years before there was a roof to stand under.

Nine hundred years of that book, and not one gap in it.

This season the pattern started dissolving. There is no water in this chapel: no well, no spring, no leak in the roof, and three wet patches on a floor that has been dry for eight hundred years.

The keeper has stopped taking bookings, will not say why, and has not written it in the book.

THE ANSWER IS ON THE PAGE, NOT IN YOUR HEAD. The inlay is a salt pan: a dry sealed layer laid over a brine spring, a technique still used in working salt country, and it works precisely because it stays dry. It has stopped. Everything the party needs to reach that is written into the scenes, so nobody has to invent the solution at the table.

THE MONSTER IS THE THING THAT WAS KEEPING IT SHUT. Eight centuries of doing one job, standing over the hole, and losing. Below half its hit points it stops fighting and starts sealing - it cannot do both. The best ending in this adventure is hitting it until it stops fighting you, and then backing away.

WHAT YOU GET - 39 pages, and nothing left for you to invent
- 6 scenes, one more than the usual five, because an investigation needs two threads
- 2 battle maps in three versions each - DM, player, and no grid, 70 px per 5-foot square
- 4 ready-to-play 2nd-level characters. No session zero
- 11 secrets, tables and printable handouts

PART OF THE SALT ROAD. Sixty miles, sixteen stops, each a day apart. Every one of them has noticed the same thing and not one of them has said so out loud. This adventure stands completely alone - it needs nothing from any other - but a table that plays four of them starts comparing notes without being prompted.
THE FILES - four PDFs: A4 and US Letter, each in colour and in a printer-friendly build. The printer-friendly version is the same book in pure white, nothing removed. Plus 6 map images.

Compatible with Fifth Edition. Instant digital download - nothing is posted.
