Horus Heresy: Legions Imperalis: Reaver Titan Graviton Obliterator & Volkite Annihilator

Like the larger destructor, the volkite annihilator also relies on the devastating power of heat, and is a similarly flexible weapon, able to threaten any enemy unit. Similar to the ruinator, the graviton obliterator also has the Graviton Pulse trait, making it more effective against better-armoured enemies, and capable of destroying structures, with the bonus of pulverising any foes sheltering inside.
