The scientifically advanced Kengen have been driven out, and the Masuto Imperial Dynasty has been restored. But freedom in Soburin is a fragile thing. Now, the 24 warrior clans war amongst themselves using forbidden technology, dark magic, and steam-augmented weaponry. Worse still, a legendary, corrupting fog, the Mists of Akuma, sweeps the land, transforming victims into bloodthirsty monsters.
Storm Bunny Studios has brought its critically acclaimed Eastern fantasy noir steampunk setting to Bundle of Holding. This massive offer packs in everything you need to run Dungeons & Dragons 5th Edition (supporting both the 2014 rules and the updated 2024 Anniversary Edition) in a decaying world where survival is a benchmark, not a guarantee.

The Meat of the Campaign
Mists of Akuma radically expands the core D&D 5E rules to fit its grim, high-stakes setting. It introduces 15 diverse new lineages, allowing you to play as hengeyokai shapeshifters, undead necroji, corrupted Oni-Touched, or automaton steametics. The class subtypes are dripping with flavour, letting players take on the roles of steam-augmented shinobibots, gun priests, desperados, Wu-Jen warlocks, or acrobats.
To capture the noir, oppressive tone, the game introduces two new special ability scores: Dignity (reflecting your status and sense of self) and Haikotu (“fall from virtue”), which tracks the degree to which the Mists have corrupted you morally, spiritually, and physically. You will need every alchemical smoke bomb, telescopic arm augmetic, and blood bullet you can find. Survival in Soburin is merely a question of when you fall to the corruption or the chaotic oni, and what kind of legend you leave behind when you do.
