One idea could be a crossover with 'Slay the Spire'. The heroes from 'Darkest Dungeon' could find themselves in the spire, facing new and strange enemies. They would have to adapt their skills and strategies. For example, the Crusader might use his holy powers against the cultists in the spire, while the Vestal could provide healing in a different, more strategic way as the floors progress.
One common theme is the clash of different game mechanics. For example, when crossing with a game like 'XCOM', the turn - based combat of 'XCOM' and the real - time with pause combat of 'Darkest Dungeon' can create interesting scenarios.
Begin by researching both the 'Darkest Dungeon' and the other universe you're crossing it with. If it's a crossover with 'Castlevania', understand the themes, characters, and power systems of both. Then, create an outline. You could start with a prologue that hints at the crossover, like a strange portal opening in the 'Darkest Dungeon' world that leads to Dracula's castle. Next, plan the first few encounters and how the 'Darkest Dungeon' characters will react.
A 'Darkest Dungeon' crossover with 'Bloodborne' can be quite fascinating. Given the shared themes of gothic horror and the fight against grotesque creatures. The fanfiction might explore how the heroes from 'Darkest Dungeon' would fare in the nightmarish world of 'Bloodborne' and vice versa, with lots of details about the combat styles and the psychological horror they would experience.
In the darkest dungeon, there was a crusader and a vestal. The crusader was always at the front line, protecting everyone. The vestal, with her pure heart, noticed his selfless acts. As they delved deeper into the horrors, she would tend to his wounds. Their love grew in the midst of despair, a small glimmer of hope. They found solace in each other's company, and they promised to face whatever terrors awaited them together.
I really like 'Darkest Powers: The Crossover Convergence'. It takes the core concepts from the 'darkest powers' series and blends them with other related concepts from different stories. It has intense action scenes and some great character interactions that make it stand out among other fanfictions in this genre.
One key element is the shared struggle. In the Darkest Dungeon, the characters face countless horrors together. This shared experience of fighting against the odds can bring them closer. Another element is the contrast between the dark and dreary setting and the small, bright spark of love. Also, the mutual understanding and respect for each other's skills and abilities play a role. For example, a character who is good at healing may fall in love with a strong fighter because they each see the value in what the other does.
The backer stories in Darkest Dungeon are quite interesting. They often involve the creative ideas and expectations of the backers who supported the game's development. Some backer stories might be about unique character concepts they hoped to see in the game, or special gameplay mechanics they wished to be implemented.
The story of Darkest Dungeon is set in a gothic, Lovecraftian world. The player inherits an ancestral estate that is haunted and corrupted. You recruit various heroes to explore the dungeons beneath the estate which are filled with all sorts of terrors. There are battles against eldritch abominations, and as the heroes face these horrors, they can gain stress and afflictions. The goal is to cleanse the dungeons and restore the estate, but it's a long and arduous journey filled with death and despair.
In the Darkest Dungeon full story, initially, the discovery of the corruption within the estate is a key event. This leads to the recruitment of the first batch of heroes. As they explore, coming across special areas in the dungeons like the Cove or the Warrens are important. These areas have unique enemies and challenges. The hero - affliction system also plays a big role. For example, when a hero goes mad and attacks another hero during a battle, it changes the whole dynamic. And finally, the push to reach the heart of the corruption in the final dungeon is a very significant event in the overall story.
