He approached with measured steps, still buzzing and humming the Tibetian charm.  He heard the angel mock the demon, and given she had ample reason, it was only right.  His senses detected the change in the elf's breathing as well, although he couldn't risk a glance over at her.  His eyes were locked on the demon's, even in her weakened state.<br/><br/>He came up right in front of her, as she was wracked with the pain of her injuries, and stood there, hands clasped on the blade of his knife.  Then he suddenly ended the chant.  The silence rang out like a bell.  And the instant he saw a flicker in the glow of the sigils on his knife, his hand flashed out and buried the tip of the knife in her larynx, severing her vocal chords, and no farther.  As she wasn't regenerating while locked in her human form, he knew she wouldn't be able to form words now.  Her spells were useless.  He was safe.<br/><br/>He pulled his knife free (carefully, so he didn't damage anything else... yet) and stepped back, savoring her reaction.
