Path of the Slayer

Typically a Dwarvern discipline though can be taught to others, Slayers are respected and feared for their savagery and skill at arms.

Though each Slayer is a killing machine, their practices do vary from Slayer to Slayer. Some focus on agility, moving from one enemy to the next with blinding speed, some count on sheer force and swinging their weapons in wide arcs to wreak havoc amongst ranks of enemy clusters and some harness their rage and aim it with great precision.

Every Slayer marks themselves in runic symbols dedicated to a discipline, empowering their fighting skills and eventually gain some power over an element. An experienced Slayer is something to behold, taking down hordes single handed or leaping into the fray with reckless abandon against some of the most destructive beings known.

To become a Slayer is to become a weapon.
