Atomantic Shielding is an advanced technology most likely discovered during the Dark Age of Technology. This arcane technology was primarily used to protect all Contemptor Pattern Dreadnoughts. The Contemptor pattern incorporated not only traditional Dreadnought technologies, but arcane systems drawn from the ancient and guarded lore of the Legio Cybernetica of the Mechanicum. Principal among these is the compact atomantic arc-reactor core more powerful by far than anything of its size in Imperial manufacture. A series of defensive shield generators are mounted in its armoured carapace. The abundance of energy it generates can be used to grant the Dreadnought frame speed and strength as well as powerful defensive energy field systems to further increase its battlefield durability, providing greater protection from both ranged and melee attacks for the walker. However, if the arc reactor is breached it is prone to catastrophic failure, dooming the Contemptor chassis to utter destruction. The miniature atomic explosion generated by its inevitable destruction is also prone to causing considerable damage to nearby allied units.
