DUNGEONS & DRAGONS 5.5: Ravenloft Horrors Within is a major horror expansion for Dungeons & Dragons focused on dark storytelling, terrifying settings, and campaigns where players face twisted rulers and monstrous evils. The book works both as a source of inspiration and as a practical toolkit for Dungeon Masters who want more atmospheric and dangerous adventures.

Inside you’ll find new horror-themed subclasses, backgrounds designed for darker campaigns, and supernatural curses that can permanently shape characters and stories. The content works equally well for long-running campaigns and shorter horror adventures.

The book also introduces 16 detailed Domains of Dread and 17 Darklords complete with stat blocks and unique themes. Each domain explores different styles of horror ranging from gothic terror and body horror to psychological dread and classic monster stories.

Dungeon Masters will also find a huge selection of antagonists and monsters to help create memorable encounters and darker campaign settings. With more than 50 new creatures, Ravenloft brings a far more sinister tone to the table.

Perfect for groups looking to expand their Dungeons & Dragons campaigns with horror, dark fantasy, and narrative-driven adventures.
