The Second World Sourcebook (d20 3.0 Edition)
This sourcebook provides a campaign framework for combining modern-day adventuring with traditional fantasy roleplaying. It supports both d20 Modern and standard d20 rules, allowing characters from either genre to cross between worlds, alternate planes, or customized settings where technology, magic, and divine power operate differently. The book includes genre and technology rules, a sample campaign setting, eight prestige classes with more than 200 customizable powers, and an alternate feat-based advancement system. Influence rules cover over 30 organizations and 100 favors, adding structure to political relationships and social interactions.
