Magic pervades many worlds of Basic Roleplaying, for in the game every adventurer every character has the capacity to manipulate invisible powers. Though the beliefs of the user shape his or her approach to magic, all magic works by certain principles which stem from the life force of the user. Life force flows in natural currents throughout the uni ­verse. Its different forms and shapes are determined by perception.The Magic Book explains the mechanics of three independent magic systems (Spirit Magic, Divine Magic, and Wizardry) and details Ritual Magic, a system common to shamans, priests, and wizards.
