Forward Gaze Into Life

Despite the constant cold of death at your back, you keep your gaze forward into the realm of life. You release two 15-foot cones, aimed exactly opposite each other, one ahead of you that deals 5d10 vitality damage and one behind you that deals 5d10 void damage, each with a basic Reflex save against your class DC. Creatures that critically fail also take 5 persistent damage, of the same damage type dealt (5 persistent vitality or 5 persistent void).
