Castle Oldskull

This old-school fantasy role-playing system introduces players and Game Masters to sword-and-sorcery adventures and character creation. It covers basic rules for fighters, thieves, clerics, magic-users, and demi-humans, along with spells, equipment, alignment, saving throws, undead, sanity, and optional skills. Modular rules let groups choose between basic and advanced levels of complexity while building characters and campaigns. Guidance explains how to learn, customize, and expand the system for new or existing fantasy worlds.
