Argh!: The Guide to Pirates
A sourcebook for campaigns of pirates, buccaneers, privateers, and other seafaring outlaws. It supports historical, quasi-historical, and fantasy settings, with guidance for Game Masters, plot hooks, random encounters, ready-made villains, and advice on themes such as treasure, betrayal, and shifting loyalties. Players gain new skills, feats, drawbacks, advanced classes, and pirate weapons for creating sea dogs and cutthroat adventurers. The material is compatible with the Modern d20 rules.
