Unorthodox Rogues
This d20 fantasy supplement presents five new rogue core classes and three prestige classes for use in any fantasy campaign. Each 20-level class includes background information, new abilities, and progression charts, covering concepts such as an inventive trapmaker, a lazy trickster, a seducer, a grave-robbing rogue, and an assassin. The prestige classes include a dagger-focused backstabber, a thief who aids the poor, and a gang leader. The book also features more than two dozen artifacts and additional material for traps and rogue-centered adventures.
