It's a horrible time to have a curse! Each wielding a powerful item to a family legacy, your players are a group of young adventurers who barely survive an attack on their order of vampire-hunters by agents of Dracula. After escaping, they discover Dracula has placed a curse upon the land which makes restful sleep difficult outside of hallowed areas. Dracula, "alive" on another plane but dead on this one, must be resurrected so they can kill him, end the curse, and avenge their dead. To accomplish this goal, the player characters must journey through forest, marsh, hill, and underground paths to retrieve relics of Dracula's last life from keeps and fortresses overrun by monsters and the undead. If they can resurrect him, he will be weak and easy to kill... but the adventurers aren't the only ones who want Dracula on the Material Plane, and Dracula is not the only vampire in the world. Gameplay overview This adventure takes the players from 2nd through 9th or 10th level on a milestone basis as they choose where to travel in what order to retrieve what they need. Starting at a happy gathering at the Belmonte Order, which the characters are hereditary members of, the campaign kicks off with a bang as the group retrieves their chosen legacy items, salvages what other gear they can in a race against time and a growing number of foes, and then escapes to begin their quest. In addition to the six main "dungeons," there are two optional regional lairs, traveling vampires, and many foes along the way. Most of the towns in the area have managed to survive, providing points of light at which the party may stop, long rest safely, acquire supplies, and socialize. Travel is hazardous! 5e classes are balanced for resource management across a 5-8 encounter adventuring day. The campaign is designed to have a semi-variable flow of encounters as the party traels around the area. Encounters grow progressively more difficult as time passes and the party spends more time within a region. These are not random encounters rolled on a table, but encounters designed to be unique to each area's geography, combat terrain, and mix of foes. As the party spends more time in a region or revisits it, the encounter difficulty increases. Dracula's curse requires a Constitution saving throw to successfully long rest outside of Hallowed areas (towns). The difficulty scales up over time, forcing the party to balance speed and safety as they try to accomplish their goals without pushing beyond the limits of what they can handle. The game concept, general map layout, and some enemy distributions are loosely inspired by Castlevania II for the NES, one of the forerunners of the "Metroidvania" genre. Dracula's Curse is indeed a game in which the forests are dark and full of monsters, and every night is a horrible one to have a curse. Includes 15 Legacy items, from weapons like whips and swords to a shield, a belt, or a decanter of holy water 60+ enemy statblocks 8 unique dungeons with unique layouts & challenges 5 inhabited towns with multiple named NPCs 100+ travel encounters (expect to use 30-50%) The module is printer-friendly with no artwork and straightforward grid maps for location-based encounters which require one.

He is rumored to have built a dungeon there. Who knows what strange purposes the mad warlock has for the Jade Hare? In any case, the precious statuette's theft is an intolerable strain on the honor of the village and all the tribe therein. A party must be assembled to confront the warlock. This party may consist of none other than yourselves. Won't you save Dar el-Tamyya's ancient honor, and thwart whatever sinister plans the warlock has? TSR 9259

A goblin warband has found the secret tunnel which leads from the dwarven keep of Hearth-Home to the nearby hills. The tunnel is intended to be a means of escape if the keep ever falls to attackers, but now it has provided goblins with an easy way into the Underkeep. So far, the goblins have confined their attentions to the various underground rooms that make up the Underkeep, but sooner or later they will find a way to the surface. They pose a serious threat to Hearth-Home - the goblins must be cleared out of the Underkeep so this breach in security can be repaired before the orcs hear of it and overrun the dwarven keep. This adventure is slightly more challenging than Red Hand Trail, and it is recommended that it is played after that quest and before Palace of Dread. However, the scenario in Trouble Below can easily be played independently from the rest. Part of TSR 1076 The Goblin's Lair
