From publisher blurb: Where a blacksmith finds home in the heat and embers of the forge, a master-at-arms both outfits their allies with the weapons of war while also training their bodies and minds. The master-at-arms is able to prepare their allies for unusual environments, challenging encounters, and strange foes by pushing himself and his allies through strict drills and imparting his combat wisdom. The master-at-arms is an archetype for the Spheres of Might blacksmith class.
