Stave of Supremacy
The Stave of Supremacy is a Grey Knights relic Nemesis Warding Stave that is heavily warded by engraved runes.[1]
These runes also give the weapon power over the energies of the Warp across a wide area. This ability proved to be instrumental in the survival of the Grey Knights aboard the Titan's Hand, after its Geller field collapsed while the ship was in the Warp.[1]
