Waterdeep: Dragon Heist & Descent into Madness (Mad Mage Reskin)

About the adventure

Your company has come to Waterdeep with a charter, a plan, and one very ambitious goal: breach The Undermountain and bring back everything that isn't nailed down. You're not hired swords looking for work — you're founding members of a treasure hunting outfit, and that means titles, responsibilities, a headquarters to build, and a silent backer who expects returns. The greatest dungeon in the Forgotten Realms has swallowed armies. You're going to treat it like a business opportunity. This campaign runs Waterdeep: Dragon Heist and Dungeon of the Mad Mage as a single connected story. The city comes first — you'll need a base of operations, allies in the right places, and enough gold to fund a real expedition before that well opens. Waterdeep is beautiful, dangerous, and full of powerful people who have opinions about what goes on beneath their streets. Navigate it well and you descend with resources, contacts, and leverage. Navigate it badly and The Undermountain will eat you alive. Then the real work begins. Twenty-three levels of megadungeon carved out by a wizard who stopped being sane centuries ago. Rival factions. Impossible traps. Treasure that makes the risk worth it — most of the time. Every session is a deeper dive into the most dangerous real estate on the Sword Coast, and your company's reputation rises or falls on what you bring back up. This is a long-term campaign for players who love dungeon crawling, tactical combat, and building something together at the table. If you want to explore every room, map every corridor, and argue whether the swallow is African or European, this table was made for you.
