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!

Sewers of the Underguild is an adventure designed for characters of at least 11th level, and characters up to 15th level will find plenty of challenges. Hidden within these narrow passages and filth-filled channels is a guild of vampiric rogues, led by their master Sangre and his aide, a nycaloth called Ankoz. Deadly traps abound, so a skillful rogue will be a lifesaver. Because of the high likelihood of desperate combat with numerous vampiric and monstrous opponents, it is suggested that a cleric and at least two fighters be prepared to beat back the many watchdog monsters the guild employs. You can hide the locales in Sewers of the Underguild in any ruin or location that fits your campaign purposes. A thriving metropolis that just happens to have a large crime and vampire problem would fit the bill nicely. In the Lost Lands campaign setting of Frog God Games, the Underguild is located in the sewers beneath the ruins of Curgantium, the ancient imperial capital of lost Hyperboria. Located at the edge of the modern Kingdom of Foere, the Underguild still finds itself located centrally enough to pull the strings of its weblike network running throughout the former lands of the Hyperborian Empire.

This adventure contains, 2 pages of new magic items, 8 new monsters and NPCs, a full write-up of Bwimb II, the Paraelemental Princess of Ooze, an entity referred to in many D&D products but never fully fleshed out and stats for the 3rd edition iconic heroes Regdar and Mialee, who play a major role in this adventure. It's got over 10 pieces of original art, full color maps, tagged and untagged, and a special handout for the player who obtains the Ooze Fist of Emirikol. This adventure builds on the story begun in the platinum-selling Castle of Corellon and the follow-up, Warpath of Gruumsh.

An army of orogs and ogres is gathering to the Warlock's banner: Are your heroes equal to the challenge of the twisted magic of the Warlock of the Stonecrowns?

He discovered his wife was cheating on him with one of his employees and while in a drunken stupor trying to create a discreet potion to deal with the two of them, he let loose an infectious plague on the lab which turned all but a lucky few in the facility into shambling husks of their former selves., fused with their own creations as their minds turned to know but one thought - rage. This dungeon has rules to modify all encounters for a group of players levels 4 through 6 and is intended for a party of four. If you have more players, feel free to adjust the difficulty up one level for each additional player or simply tune the monsters to your needs. This dungeon contains many original enemies, a unique puzzle, and an environment that is meant to bring a sense of terror and anxiety on your players. I consider this to be the Horror-themed adventure of the module so feel free to add some creepy music and extra details along the way to bring the area to life (or death).

Worse yet, spring is overdue; winter refuses to relinquish its icy grip. Only one vile force could cause such chaos: The illithids have risen up once again, ready to enslave the surface races. Now, as never before, the world needs great heroes, mighty adventurers who will challenge the illithids; dark agenda. A Darkness Gathering is the first of an adventure trilogy (continuing with Masters of Eternal Night and concluding in Dawn of the Overmind) that pits brave adventurers against the brain eating mind flayers. Dungeon Masters can run each individual adventure of the trilogy separately, or they can be linked together to form a seamless, epic-length adventure.

The town of Byr is in need of heroes. Residents of the town of Byr have been kidnapped. Some think it was marauding Hobgoblins, but a grizzled and crippled veteran who helped to drive the Chagmat (monstrous spider-people) back many years ago believes that the Chagmat are back.

People keep asking for "beginner" dungeons. Everyone can name "classic" dungeons - Tomb of Horrors, Barrier Peaks, Ravenloft, etc. - but in order for those adventures to make sense, there needs to be some sort of introduction. It's like all the adventures we have are Bach concertos. People keep writing amazing works of staggering genius, but someone needs to write a book on how to play the piano. I had the same questions, and since I couldn't find anything satisfactory, I decided to write the kind of dungeon I would have loved to find. I wanted to write the best basic OSR dungeon for beginners that I could, and I also wanted to show the design process. If you like this dungeon, please share it, tell people about it, print copies and leave them lying around local game stores, or email this post to friends who have "always wanted to try D&D but don't know where to start". The entire thing is and always will be free.

"The creatures are just too intelligent, too crafty, and too strategy-minded to "rampage." Rampaging brings the wrath of oath-bound knights, powerful mages, and divinely-protected priests. Why would a dragon want such attention, unless it had some special secret, or unless it was insane? Or both. The northern reaches of the Derideth Swamp were once plagued by a rampaging dragon. This black dragon, named Storamere, took a mad glee in attacking human villages, wiping out orc camps, driving off the lizardfolk, and decimating farmland. He met his untimely end, though, in an ambush devised by the monks of the Order of St. Chausle. Storamere died with a curse upon his draconic tongue: "you could not have defeated me in my lair," he told his slayers. "I am forever invincible in my lair." Now Storamere is back, with a horde of his misshapen half-dragon offspring, to have his vengeance. All that remains of the once-heroic monks are two old men driven mad by their last encounter with the black dragon, so it falls to a band of adventurers to again defeat the mighty dragon -- this time in his palace, where the boastful Storamere claims he is at his strongest." Includes maps and damage rules for navigating Storamere's lair, a semi-solid palace made of a dangerous, corrosive liquid five feet thick and located on the ethereal plane. Most of the monsters in the lair have the Half-Dragon template applied. Published by Atlas Games
