A Supreme Shield Matrix is an advanced Necron defensive technology used by Tesseract Vaults when they are accompanied by eight surrounding Monoliths in a Baleful Necropolis formation. When activated, a Supreme Shield Matrix projects a powerful energy field around the Tesseract Vault that can deflect even the heaviest of enemy firepower. If the Tesseract Vault’s fellow Monoliths are close enough, they too can share in the protection of the Supreme Shield Matrix, whilst the Tesseract Vault is able to draw upon the Monoliths’ power and increase the defensive properties of the shield. Thus, the energy field only grows more powerful with every additional Monolith under its protection, making the formation a potent threat to any foe.
