Disruption waves creates a cone of positive energy that originates from your hands and extends outward toward your opponents. The disruption waves harm only undead creatures as it fills them with positive energy, disrupting the negative energy which fuels them. An undead creature struck by the disruption wave must succeed a Fortitude save or be destroyed. If the save is successful, a disruption wave still deals 1d8 points of damage per level (maximum 15d8) to any undead struck. This effect bypasses an undead creature's normal immunity to Fortitude saves.
