Two different Pathfinder/OGL resources here, one for primarily for players and one for Game Masters:
Anachronistic Adventurers: The Daredevil is part of Super Genius Games’ Anachronistic Adventurers (3rd in the series) framed around the idea of people from modern(ish) worlds carried away into a fantasy world. The Daredevil represents the most adventurous of the adventurers, people who rely on raw cussedness and luck to get the job done and survive. While framed around the modern person in a fantasy world, it works as a pure adventuring class as well. It is full of good, solid ideas for those who like these sorts of characters.
