Illness and Disease: Ancient Diseases for 5e

Before antibiotics, before germ theory, before any of the tools modern medicine takes for granted, illness was a force as terrifying and unpredictable as any monster. A cough could signal consumption. A festering wound could become gangrene or tetanus. A city's water supply could unleash bubonic plague. Illness and Disease brings that grim reality to your 5e campaign in 52 pages of historically grounded, ready-to-use rules.

34 Diseases from the Ancient World

Drawn from historical medicine, classical sources, and the grim realities of life before modern healthcare, this supplement presents 34 diseases as ancient people understood and feared them — dropsy, consumption, anthrax, falling sickness, bubonic plague, and many more. Each disease includes full game mechanics, symptoms, progression, and consequences. Some wear characters down slowly over days or weeks. Others strike fast and can change the course of an adventure in a single session.

Whether you need a single affliction to complicate a wilderness journey, a plague threatening an entire city, or a harsher world where sickness truly matters, this supplement gives you everything you need. It's ideal for ancient, mythic, low fantasy, sword and sorcery, and historical settings — and works seamlessly with any 5e campaign that wants disease to feel dangerous and real.
