From publisher blurb:
Join your power to draconic essence!
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 second of these classes is the mighty dragoon, masters of draconic power and united with powerful drakes. Drawing on power beyond their reckoning, dragoons are avatars of vast power beyond their own understanding, living conduits for the might of dragons.
In addition, each class comes with new archetypes along with new talents for the boxing, equipment, and scoundrel sphere.
