Gravity Pulse

A Gravity Pulse is a form of Necron technology used exclusively by Obelisks. When activated, the Obelisk manipulates the natural gravitic fields of the planet it is located on to produce an expanding wall of earth-shakingly powerful force. If an enemy aircraft is hit by this sphere of force, it inevitably is smashed aside and severely damaged, often being turned into a plummeting wreck as the pilot loses control of his aircraft.
