The Pathfinder Society dispatches you to the catacombs called Cassomir's Locker to find the source of a rat cult breeding monstrous vermin.

The Hag's Hexes is a 66 page guide designed by Dungeon Masters Guild luminaries like JVC Parry and Janek Sielicki alongside rising stars and old stalwarts like Matt Butler, Matthew Gravelyn, and Tim Bannock. It was created with one thing in mind: to make hags more than the sum of their (often meager) Challenge ratings, giving them the mechanics, roleplay potential, and weird magic that can inspire campaigns, lay low kings and warlords, and potentially ensnare unwary Player Characters into campaign-changing curses or long-term bargains that force them into terrible moral quandaries! Split into five chapters, the authors have provided everything a DM needs to terrify their players for years to come. The Bestiary features over a dozen monsters; some are new hags, some are their minions or even their mobile lairs, and one of them -- the Shaitan AKA Desert Hag -- was featured in Monsters of the Guild! Bargains & Curses is a chapter filled with ideas that can kick-start campaigns, threaten valued NPCs, or put Player Characters' very existence and morality at stake. Chapter 3 includes two dozen items of wonderment, weirdness, and dread, ranging from fairy tale-inspired items of whimsy to terribly cursed items of horror. Chapter 4 is titled "Filthy, Vile & Downright Dirty" and provides dozens of roleplaying tips to make hags come alive, new mechanics inspired by and expanding on Volo's Guide to Monsters (coven spell lists, aunties, grandmothers, alternative coven members), and ends with useful combat tactics for each of the hags from the Monster Manual and Volo's Guide, as well as tactics for covens. Finally, Chapter 5 presents five encounter groups (with sub-encounters) to give you quick story seeds and monster lists that you can put together in minutes to create a single encounter or to inspire a full campaign, and ends with three full-length adventures -- each with 3-5 encounters -- that showcase many of the new monsters, rules, magic items, and so on that appeared in earlier chapters. Each of these adventures comes with an encounter map meant to act as inspiration for hag lairs, and they include useful mechanical ideas for terrain effects and descriptive keywords listed directly on the map for added inspiration and easy customization!

Prime Plane Immortals are dying like flies: nasty, violent deaths. The Hierarchs suspect Entropy, as usual, especially with all the rumors of demons' involvement. To top it all off, one of the Hierarchs is missing - Mazikeen. Your Mission as novice Temporals, should you choose to accept it, it to find Mazikeen, uncover his kidnaper, and bring him or her to a court of Immortal Justice. This entails much more than mere detective job - it also means taking part in the Immortal Olympics and going plane-hopping with the best (or worst?) of them. Should you not accept this mission, the fate of all Prime Plane Imoortals rests on your heads. (Well, it rests there anyway, but this is meant to make you more than a little guilty about not accepting - after all, you're supposed to be duty-bound and all that kind of thin, and I you don't do this, then who will? Huh? Did you ever think about that, Bucko?) TSR 9207

Do you want to run or play an adventure where characters start at level 13 instead of ending at level 13, and actually get to progress to 20 like the rules say they should? Do your players like to travel far and wide, exploring a huge unknown area? Do your players like to change their plans on a whim, and travel somewhere other than where they told you they planned to go last session? Do your players feel like fighting against an empire at odds of 20,000 to 1? Do your players want to commit occasional acts of sky piracy? Do you want an adventure that is designed to handle players using Scrying, Transport Via Plants, and Teleportation on a daily basis? If you answered yes to some of these questions, this adventure may be for you. Check out the detailed preview packet, which includes a campaign log showing how this adventure has actually played out. WARNING: FULL OF SPOILERS; VERY LONG. Against the Idol of the Sun is an epic hexcrawl campaign designed for high-level play. Adventuring parties should start at about level 13, and will likely end the campaign at level 20 with multiple Epic Boons. As a hexcrawl, there is no set adventure path that the party must follow. There is only one encounter that's even close to plot-mandatory aside from the climactic battle. Anything else can be skipped or handled in any order. The players are free to move about the map in any direction at any time, limited only by the risk of enemy action and encounters. The DM, meanwhile, is encouraged to have foes react to and actively hunt the PCs once they become a threat. Along the way, they may find and explore a number of dungeons, including a millenia-old laboratory in the grips of a time distortion, several mines that were abandoned for good reason yet may hold wealth within, and other challenges appropriate for high-level characters. This module is heavy on Exploration and Combat, but the Social aspect of D&D also is necessary as the player characters meet new peoples, work to convince them that they can make a difference, motivate them to action, and create overall plans for the NPCs and factions to follow off-screen to support the players in their main assaults. The key set piece encounters, which are optional but highly probable, involve attacking well-defended temples in the centers of enemy cities. Planning for these attacks will require paying attention to reconnaissance, timing, the use of allies, how to enter, and how to exit and break contact succesfully when dealing with enemies that fly faster than most player characters can walk. The adventure does not include artwork, and the maps are basic.

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).

You've been sent beneath the Lodge to destroy whatever it is that Bossell's lover has become—will you survive his secret or find yourself transformed as well?

Far from the nearest town, hidden deep in the forest, lies a marshy, boggy valley. Woodsmen and hunters shun the place—kept away by rumours of a terrible beast lairing within and of a ghost haunting the valley’s boggy mere.

Dare you explore the Shunned Valley of the Three Tombs?

The Thorn Hag, an ancient evil thought vanquished by the Elf Queen and her heroic companions many years ago, has arisen from the dead. A fey harp, created from the heart of the treant that perished in the battle, has gone missing from Satyrs' Glen and the Thorn Hag seems to be behind it. The PCs must track the missing harp through a warped and eerie wood and into an unseelie area of the Feywild to stop the Thorn Hag wreaking revenge upon the Elf Queen before it's too late - the clock is ticking. The Sylvan Harp is a D&D 5e adventure for 4-5 PCs of the 1st tier (Levels 1-4). The adventure has been designed with suitable alternatives to run the adventure for 1st, 2nd, 3rd or 4th-level characters, including advice for adapting creature numbers and/or powers to suit the level of your party. The adventure is estimated to take 8-12 hours to run. A timeline of events, and guidelines on how the actions of the PCs can affect those events, is included. The adventure includes nine new creatures: gwerthin, satyr bard, ash guardian, light guardian, treant spirit, pixie rot zombie, green dragon skeleton, thorn hag and thorn hag's hut. It also includes two new magical items: a powerful magical harp with a dark hidden secret and a crystal ball of clairvoyance. Also includes a player handout of the rhyming riddle of the fey, and maps of the area and a darkling tomb. Requires Volo's Guide to Monsters.

Legend tells of a long-dead empire of sphinxes, ruled over for millennia by a great queen named Ankharet. She fell into darkness and her empire was shattered, as her subjects rebelled and cast her down. Unable to kill her, it is said that they bound her with great magic and buried her in a tomb, to wait for the foretold heroes who would be able to slay her and end her evil forever. Their empire in ashes, the sphinxes scattered to roam the world in bitter freedom, save a single great androsphinx. On the edge of the mysterious Barren Hills, between the mountains and the Great Desert, there is a gigantic statue of a crowned gynosphinx, ancient beyond reckoning. At its feet, a great androsphinx known as Khubsheth the Prophet has dispensed counsel and prophecy to all who come to him for longer than mortal records can tell. The heroes have come to visit Khubsheth, whether for counsel, prophecy or out of curiosity, but as soon as he lays eyes on them, he attacks! Upon his defeat, he tells them that they are the heroes foretold by the legend of Ankharet. Ankharet ruled over a long-dead empire of sphinxes, but she fell into darkness. Her subjects rebelled and cast her down, but were unable to kill her. It is said that they bound her with great magic and buried her in a tomb, to wait for the foretold heroes who would be able to slay her and end her evil forever. Kubsheth the Prophet tells the heroes that they must enter the tomb of the long-dead sphinx queen, kill her, and destroy her cursed crown, an artifact of tremendously evil power. As his blood seeps into the sands, a doorway opens at the base of the statue, leading down into darkness…

When huge stones fall out of the night sky, A deadly curse settles over Gravencross. Help the village exorcise the Demon Stones. “The sun had set an hour ago, and the rain lashed down and the wind howled on the dark moor. A storm this late in the season was unusual, but this one seemed different. The clouds were more menacing, tinged with anger, the rain colder and more biting than usual. Skerrill had to find the lost calf and get him back to the farm before his father came back from the city on business. He’d been looking for two hours now, and he was right in the middle of the moor when the storm hit. He knew he should have turned back as soon as darkness fell, but then he was never the brightest boy in the valley. If only he had remembered to lock the farm gate. The calf was now likely dead anyway having stumbled among the boulders and rocks, panicking in the dark, and then fallen in a floodwater stream and drowned. Either way, he was in more trouble than he could imagine. Suddenly, a bright flash of white light and a roaring peal of thunder were preceded by an explosion as a huge object fell from the sky and impacted the ground of the moor no more than a stone’s throw from him. Dirt, mud, water, and debris erupted from the impact site, flying high into the air and then covering the moor for hundreds of feet all around. Skerrill was knocked to the ground instantly and covered in the fallout from the blast. His ears rang and his head spun, but he staggered to his feet in a daze. He stumbled to where the blast had happened only moments before, and in a depression in the ground lay a huge stone glowing orange as if hot. Skerrill passed out. Two more thunderous explosions crashed in the distance.”
