Path of the Slasher

From publisher blurb:

For some Barbarians, their rage has a darker manifestation that consumes them, ultimately leading their fury down a path of murderous intent. As their fury grows, demonic entities begin to take notice, reveling in the carnage left in the barbarian's wake before goading and exploiting their killing skill for personal gain. Path of the Slasher Barbarians are often seen as elusive boogeymen with superhuman strength and an unreasoning hatred. Others see a typical horror character. All that's missing is a terrifying mask and a group of clueless teenage victims.
