An official OSE supplement of demons, cults, and dark magic.

Ruttigers Almanac is an OSR-compatible tabletop roleplaying game system that combines frenetic, fun mechanics with a clutch of mini-games to bring chaos to your table, alongside an expansive setting to explore and plunder.

Get ready to enter your very own World Dungeon! Play as a familiar face, such as 🧨 Carl, 👑🐈 Donut, 🐊 Florin, 🐐 Prepotente, or build your own unique crawler, complete with a customizable class and race (if you survive to the third floor)!
