From publisher blurb:
Blend illusion with dancing deadly steel!
Welcome to the Lost Champions! In this series, we explore new classes which utilize the critically acclaimed Spheres Systems. Each of these classes work together to blend both systems into a unique experience that allows players to decide between dazzling magic and exciting martial combat! These classes were designed with this in mind, giving access to both magical and combat talents.
The first of these classes is the mountebank, a wily trickster dedicated to deceiving others and leaving them dazed and confused. Consummate rogues, mountebanks serve to combine magical talent with mundane guile in order to fool their opponents into seeing things their way.
In addition, each class comes with new archetypes along with new talents for the boxing, equipment, and scoundrel sphere.
