Diamond Heist


At the request of a stranded djinni, you have three days to steal a diamond from the enchanted vaults of the Modern Artworks Museum. Investigate its defenses, disable magical wards, bamboozle the staff, battle a golem, and escape with the prize! The reward: a single wish - the power to bring about almost anything you desire.

A one-shot adventure for 6th-9th level characters, designed to take 4-6 hours of play. Includes a virtual tabletop map and screen-reader accessible PDF. You can veiw the entire module in preview mode, so take a look!

Highlights of the adventure include (and are not limited to):

  • An alternate skill check system that keeps clumsy characters involved in the heist
  • A fight to the death with fantasy-Botticelli's Birth of Venus
  • The Modern Artworks Museum, a trove of sculpture, frescoes and tapestries
  • Museum events: sketch and sip, a gala, seminars!
  • Museum brochure, including handy map and exhibit descriptions
  • A wish

Clever and light-hearted, Diamond Heist adds brains and Renaissance style to any urban campaign. This adventure centers exploration, planning and roleplay. Players match wits against various spell effects, discovering and disabling magical wards to access their prize. A cumulative alarm level system replaces pass/fail steath skill checks, so one bad role doesn't ruin the heist.

The artworks described are based on those of Renaissance Italy, with frescoes, marble sculpture, and haughty nobles aplenty.

Content warnings: Death of a loved one, mentioned.

This is a great, well thought out adventure with lots of room for creative problem solving by players. There is a perfect amount of flavour text for each location and NPC, and the mechanics are well-presented and easy to understand. Perfect for a heist [...]

I love the work that went into the creation of this adventure--all of it was incredibly useful and if I had more than 2 hours with my players I would have loved to use the framework of the various events in the museum. In a world of wishful thinking, [...]

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
