From an empire’s ashes arise cruel warlords, savage hordes, and man-eating giants—all seeking the cosmic steel to become like gods—in this pulp sword & sorcery mega-adventure for Old-School Essentials.

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)!

The BX Advanced book is over 350 pages of player options and expansions for old school gaming, written for OSE and BX-style games in mind. New classes, spells, a simple skill system, and more.
