The Thanatar Calix is a mobile artillery platform that folds the arcana of several secretive Mechanicum factions into one devastating construct. Its Sollex heavy-las cracks open the heaviest bunkers, and its graviton ram smashes down whatever's left cowering inside. If your opponent likes to dig in, this is the answer.
