While not as destructive as some more mundane Daemon Weapons, the inhabitant of the Accursed Crozius grants its bearer unholy resilience, allowing him to shrug off blows that would maim even a Chaos Space Marine. But the most insidious power of the Accursed Crozius is its ability to infuse the very words spoken by its bearer with the energies of the Empyrean. Combined with the oratory prowess of the Apostle, it makes their blasphemous speeches utterly convincing, and many a world has fallen into Chaotic corruption without a shot being fired in anger, simply by listening to a Dark Apostle spread the words of his Primarch Lorgar.
