Guurahk

Guurahk is the Master of Disintegration. When Guurahk uses its tool, a web of cracks appears in the target, and eventually it collapses to the ground. But the staff would be purely nothing without Guurahk's skill at divining weaknesses - he's able to "see" the stress point in a structure or a foe's weakness, and target it immediately. Guurahk's staff can shoot a cone of dark energy, disintegrating whatever it hits.
