From publisher blurb:
Rogue talents are a crucial part of the core rogue class. They received an overhaul (adding the categories of edges and grand talents and combining the assassin, ninja, and rogue into one flexible stealth-and-trickery class) in The Genius Guide to: The Talented Rogue, and this book is designed as a follow-up to that product. However, to use these new talents with the ninjas and rogues from the core rulebook the only changes required are to allow ninjas to take these talents and advanced talents as tricks and master tricks.
As a rogue gains experience, she learns a number of talents that aid her and confound her foes. A rogue cannot select an individual talent more than once, unless the talent specifies otherwise.
