Along with the announcement of Waterdeep: Dragon Heist, Wizards’ also announced another adventure which would follow on, taking players from level 6 all the way up to level 20!
Unless you count the dungeons included with The Yawning Portal book this is the first time in an official 5th edition adventure that players will have the opportunity to go all the way to the level cap.
So, given the information that’s been released so far this adventure comes directly after Dragon Heist but I have a feeling it won’t be so closely tied to the first part that you’d have to have played through it to play this. Which means… returning characters from prior campaigns! Here’s the official product listing from Wizards’
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!
For those not in the know there’s a tavern in Waterdeep called the Yawning Portal which is run by a guy called Durnan who looks alot like Lemmy from the band, Mötorhead. This tavern has a large well-like pit in it’s centre where daring adventures pay Durnan a few coins to enter the depths below. Most of these adventurers never return, or if they do they only explored the first few levels because what lies beneath the tavern is the terrifying Undermountain. A large subterranean dungeon that extends forever downwards with nobody ever reaching the end.
The book will allow you to explore 23 of the dungeons levels with each having their own unique feel and theme. Meaning you could be battling frost giants on one floor and find yourself fighting fire elementals on the next. Some of these floors will be completely non-combat based, relying on players to solve puzzles and riddles in order to progress. The mega dungeon will also have plenty of allies as well as enemies and allow you to visit the notorious subterranean port of shadows – Skullport.
They’ve been clear that this isn’t going to be a short adventure. Players meeting on a weekly basis will take about 8 months to get through it which for our groups monthly sessions probably means 2-3 years!
