>RIP AND PURGE
You continue to bullrush the daemon, roaring in the biggest voice you can manage on your vox- outright bellowing admonishments in the most holy variation of Binaric you know, punching at it's flesh with your fists, pulling at the corrupted Dukta- burning your hands as you do so. It hurts, but you ignore it. This daemon must be BANISHED- you find yourself reciting an old prayer you only half-remember learning in the Schola for your trades:
"O God of machines and Lord of metal, Creator of the fiery ranks, and Fashioner of the fleshless spirits, the Artisan of heavenly things and those under the heavens, Whom no man has seen, nor is able to see, Whom all creation fears: Into the dark depths of The Warp You hurled the son who had become proud, and who, because of his disobedient service, was cast down from the height into the Warp, as well as the allies that fell away with him, all having become evil daemons-"
The Astartes can't help but watch. A weak cheer comes from the Marine you met first in this forsaken place- he's still alive, thank the Omnissiah!
You hold the Lucky Mechanus Charm tight in your mechadendrite as you RIP AND TEAR at the Daemon, consumed by holy fury at the daemon, even as it tries to snap at your head, tearing your hood right off. It screeches, the Warp core inside quailing at your advance.
"Grant that this- my exorcism being performed in Your awesome name, be terrible to the Betrayer and to all his allies who had fallen with him from the height of brightness. Drive this daemon into banishment, commanding him to depart hence, so that no harm might be worked against Your divine agents!"
