When the Baleful Necropolis formation is used, the Tesseract Vault is able to project this beam of potent force a short distance and smash aside or disintegrate almost anything in its way.
Such is the Annihilator Beam's power that it poses a threat even to war machines as large as Titans. If a Tesseract Vault draws power from its surrounding Monoliths, it can increase the otherwise short range of the beam and fell targets from further away.
Thus, a fully realised Baleful Necropolis formation is a potent threat to any foe at extreme ranges.
