The crap matter burns away as Ivor picks the sword up, and the crapamancer probably (unless actively guarded against magic) feels a searing sensation in the arm holding the sword. The sword almost seems to rip itself out of Ivor's grip as it falls to the ground.

Nathaniel curses as the bullets do nothing, and straps the gun to his back again. He ducks and runs as fast as he can, trying to run around the Demon towards Ivor and his sword.
