The Lost Temple of New Thundertree one-shot is designed for 5th-7th level characters.

Though it takes place in Thundertree, the adventure can easily be moved to other settings. Content warning: undead; water hazards; tentacles

Trouble Cubed is a is a pseudo-adventure with three interesting gelatinous cube encounters. These three encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL5 to 7. The encounters vary the cube's encounter situation significantly, and the tactics needed to deal with them, such as by trapping a character with a portcullis between a cube and a pit trap, placing a cube half down a pit trap, and having the cube accidentally ingest a beneficial potion (such as spider climb). Pgs. 29-30

The adventure takes players from a town devastated by an unexpected flood, through a drowned land where nature is turned upside down and desperate families cling to the roofs of their ruined homes, hiding from the monstrous products of a disordered world, through the strange tomb of an ancient race, to a profundal zone, hidden for millennia and now exposed, and finally to the Observatory itself, an eerie abandoned treasure palace, where they will encounter a pale and unexpected terror which will seek to claim their lives. The adventure is suitable for a lucky mid-range party, a stupid high-level party or an exceedingly clever low level party. It is difficult, with a meaningful possibility of character death. Should you find them, and defeat their guardians, the treasures of an ancient culture will be yours. At the final point of the Observatory is a glimpse of another world.

A long-simmering merchant conflict has turned into a war of assassination, and the PCs are called in to prevent an attempt to murder the daughter of one of the merchants. They lead her yuan-ti would-be killer on an overland chase through a canyon called Ehlonna’s Scar, which contains surprises of its own.

His name has inspired fear in legions of heroes, and his cult has lurked in the dismal reaches of the world for countless ages. His minions are savage and feral, his worshipers vile and wretched. He is Demogorgon, and his temples are nightmare realms haunted by primeval menaces and hateful legacies from a time when the world was savage. And now, a vengeful death knight has discovered one of these lost temples—will the PCs aid him in his dark quest for revenge, or will they fall before the awakened host of the Prince of Demons? Pgs. 64-83

"For Blibdoolpoolp!!" "The power of the mind and belief are wonderous, often leading us to manifest things that aren’t real. For the kuo-toa, this power is heightened, allowing their collective belief to manifest gods." Two tendays ago, a paladin of Torm was kidnapped by kuo-toa. In a strange turn of events, she was mistaken for a kuo-toa god, and whisked off to their underground lair. Barria has managed to pose as the god and now shakily leads a small faction of kuo-toa while trapped underground. With her influence being increasingly scrutinized, and with the different kuo-toa sects on the brink of civil war, it’s a dangerous time, even for a ‘god’… The heroes’ mission — rescue the paladin from the kuo-toa oceanic lair before she’s transformed into a kuo-toa god.

What is the Lost Lands? The Lost Lands is the home campaign world of Necromancer Game's and Frog God Game's own Bill Webb. This campaign has been continuously running since 1977. Many of the adventures published by Necromancer Games and Frog God Games are directly inspired by this campaign. They have evolved over the decades, and more material continues to flow from it as the dice keep rolling. Sages and wizards of legend speak of the Lost Lands—many of the players who have lived and died in Bill's campaign over the years now have a place in history (in the books). Frac Cher the dwarf, Flail the Great, Bannor the Paladin, Speigle the Mage, and Helman the Halfling are well known to the fans of Bill's work. This is the game world, and these are the adventures in which the players of these famous characters lived and died. Hundreds of players over the past 35 years have experienced the thrills and terrors of this world. The Sword of Air is the centerpiece of the Lost Lands. Currently, this epic tome consists of several parts: 1. The Hel’s Temple Dungeon—kind of like Tomb of Horrors on crack. This six-level, trap-and-puzzle infested dungeon formed the basis of Bill's game through his high school and college years. Clark Peterson’s very own Bannor the Paladin spent several real life months in the place, and, sadly, finished the objective. This is where the fragments of the fabled Sword of Air can be found…perhaps. 2. The Wilderness of the Lost Lands extending to the humanoid-infested Deepfells Mountains and providing detail about the nearby Wizard’s Wall. This so-called “wall” was raised by the archmages Margon and Alycthron harnessing the Spirit of the Stoneheart Mountains to raise the land itself, creating a massive escarpment to block invaders from the Haunted Steppes. These archmages are actual player characters from the early 1980s who live on in the legends of the Lost Lands. Over 70 unique encounter areas are detailed, and each one is a mini-adventure in itself. New wilderness areas may be added based on bonus goals described below! 3. The Ruined City of Tsen. Legend has it the city was destroyed by a falling meteor. This place forms an aboveground dungeon area the size of a city, with over 100 detailed encounter areas. It’s a very dark place…even at noon. 4. The Wizard’s Feud—This campaign-style adventure pits the players in a long-running series of intrigues and battles between two archmages. Which side will they take? Their actions all play into the overall quest, and could well determine which side wins. Law and Chaos are not always what they seem, and if the wrong decisions are made, the entire ordeal could fail. Remember, one of the wizards WANTS Tsathogga to win. 5. New monsters, new demons, new spells, and new rules for various aspects of play. 6. The Tower of Bells. This dungeon is the result of the workshop Bill ran at PaizoCon 2013, where the participants assisted him in building an old-school dungeon. Visit the tower and discover the secrets of the “artist” within. Beware: those entering may never come out!

"I was taken by the evil dogs while camping near Agav's bog. They dragged me into their lair, and it wasn't until I escaped that I knew the truth of the place: a great and bony wing buried in the side of a hill. They chained me in the dark with a candle made from foul wax and forced me to dig at the marrow. Their bonds were poorly made, and I fled several days later while they slept. What purpose did they have in mining that marrow? I cannot say..." The Marrow Mines are dug in and around the fossilized wing of an unnamed leviathan. A small pack of kobolds lives and works in the mines, which are heavily trapped. The kobolds defend the area fiercely and patrol the region around the mine. At night, a handful of urds make aerial surveys of the territory. The urds live in the deep reaches of the wing's tips.

Devastated in a war with a nearby wizards' school, the Fighters' Academy has since been surrounded by a foul and dank swamp - the Gloomfens. Since the climatctic battle between the wizards and fighters, the tower has decayed. The spirit of the head of the academy haunts the building, eternally plotting his revenge on the wizards who killed him. his loyal sutdents remain faithful to him even in death. Other foul undead have made their home in the rotting, spacious academy. From their lair, they make forays into farmsteads near the swamp in search of victims to feed their unspeakable appetites. The Problem of these terrible attacks by the savage undead will not stop until the evil that has found a home at the tower is burned from the face of the land forever. Will your party heed the call and help the town of Melinir? Will they be able to clear the former Academy of its undead? Lair of the Vampire Lord is the third in a three part adventure, The Haunted Tower. Or, it can be ran as a stand alone adventure. The choice is up to you. Part of TSR 1081 The Haunted Tower

Dragonbowl is a setting and pulp action adventure in one. It plunges a party into a rich festival scenario that revolves around a deadly gladiatorial contest, where the dangers they face in the arena are almost secondary to those they encounter in the murky criminal underworld they find themselves in: a world that stinks of corruption, human trafficking, illegal dinosaur-trading, necromancy, blood sacrifice and unnatural arcane experiments. The action takes place in a vast cavern in Mount Waterdeep, known as the Underbelly, where not only Dragonbowl Arena, but also an entire festival grounds – consisting of temples, bars, casinos, funfairs and markets - has been constructed to host this grand sporting extravaganza. With Xanathar, Jarlaxle, Davil, Volo and the Black Viper all in attendance, and scores of 'entanglements' (faction missions) to keep players busy, Dragonbowl can be played as a sequel to Waterdeep: Dragon Heist, or as a first step towards the Undermountain and the Dungeon of the Mad Mage. Equally, it can be played as a stand alone adventure, or easily transported into other settings. The adventure is written for a party of four 6th level adventurers, and easily customisable for three to five players, of any mid-tier level (the adventure contains maps and handouts adapted for both 4 and 5 player tables). The adventure is designed to last around ten to fifteen 4-hour sessions, but can very easily be shortened or lengthened according to the DM's desire. The adventure features all three pillars of play: combat (in and out of the arena), social interaction (a succession of parties and parades, where players can get entangled in NPC business) and exploration (30+ locations in the festival grounds alone).

The party has been tasked with bringing the head of the fire giant king Snurre Ironbelly to the storm giant lord Krombaalt, as well as capturing the dwarven traitor Obmi Ironwhisper. Delving into Snurre's stronghold, they will also discover the sinister drow manipulating the giants. The adventure is part of the "Against the Giants" series originally by Gary Gygax, hence the writing credit.
