Product Description -
D&D 5E - Waterdeep - Dungeon of the Mad Mage
THE GREATEST DUNGEON OF THEM ALL
Explore the mega-dungeon of Undermountain in this adventure for the world’s
greatest roleplaying game.
In the city of Waterdeep rests a tavern called the Yawning Portal, named
after the gaping pit in its common room. At the bottom of this crumbling
shaft is a labyrinthine dungeon shunned by all but the most daring
adventurers. Known as Undermountain, this dungeon is the domain of the
mad wizard Halaster Blackcloak. Long has the Mad Mage dwelt in these
forlorn depths, seeding his lair with monsters, traps, and mysteries — to
what end is a constant source of speculation and concern.
This adventure picks up where Waterdeep: Dragon Heist leaves off, taking
characters of 5th level or higher all the way to 20th level should they
explore the entirety of Halaster’s home. Twenty-three levels of
Undermountain are detailed herein, along with the subterranean refuge of
Skullport. Treasures and secrets abound, but tread with care!
