From publisher blurb:
Paths of Battle continues the Paths of Shadow series, which was launched to examine and expand on the expert paths presented in Shadow of the Demon Lord. This supplement focused on paths allowing characters to develop their martial skills, and presents again the berserker, fighter, paladin, and ranger, each gaining new background options to help players better fit them into the game. Several paths also gain new benefits to make them even more appealing as potential character options.
Finally, Paths of Battle introduces the knight, a brand new path for characters devoted to protecting the innocent and championing noble causes as the Shadow looms ever larger. Do you have what it takes to fight the Demon Lord with cold steel and gritty determination?
