So I already know that Piper's charmspeak isn't going to work on these shadows, but I'm curious about her saying the word "Lawkamercyme." Once she notices them shrinking back from it, would there be any way for her to enhance that using her charmspeak? Since it works by suggesting that a person wants to do a thing, if she says "Lawkamercyme" while wanting them to retreat or be afraid, would that carry over and affect these shadows? Or would she add no additional power to the word itself?
