Masters of the Gun
This supplement expands firearm-based character options for Pathfinder and other 3.5 OGL games. It introduces three prestige classes: the gun mage combines firearms with magic, the hair-trigger renegade specializes in high-capacity weapons and rapid attacks, and the sharp shooter focuses on precise shots that bypass defenses. Each class includes distinct mechanics and new class features. The classes complement the gunslinger but do not require levels in it, while use of the firearms rules from Ultimate Combat is required.
