Publisher's blurb: Plunge your characters into an underworld of corruption, theft, death, and money, complete with its own rules, lingo, and protocols. Learn what secrets link the corrupt city of Skullport with the shining jewel of Waterdeep, and use them to make as many dragons as you can. Can your characters come out on top as they pit their wits against the Waterdeep city guard, the pitiful defenses of their targets, and even their own greed? A shadowy figure that calls themselves “Mr. Porter” always has a job for characters ready for some quick and dirty work. Your characters clearly have the skills needed for some skullduggery; or, at least Mr. Porter believes they’re desperate enough to try. Once you’re in, there’s no going back, but the reward is worth it…isn’t it? "Mr. Porter's Tome of Skullduggery" is a 40-page supplement that lays out what all this skullduggery business is and how you can use it to add a bit of variety and a little extra money to your exploration of the City of Splendors. It includes a brief history of skulduggery in Waterdeep, an explanation of how to run an adventure like a heist, and a series of 10 heists that are quick to set up and quick to run. Spanning levels 1 through 7, this product is perfect for the adventuring group who wants to see and do more in Waterdeep before they take the plunge into Undermountain.
