Harry had taught her a few spells, so Murphy was comfortable enough with the loaded bazooka that was Harry's major wizard mojo. And she really needed to get out and away from... well, thinking about things. Thinking about Harry. Thinking about what she was doing down here. Thinking about Harry's housemate whom he was currently in love with.
She'd heard a lot of things about the corn maze at the fair, and it was her duty to see what she could do to help people, even if she was currently working with a very different way to help people.
As a vampire headed toward her, she pointed her hand at him, focusing her will.
"Fuego."
A nice ring of fire separated them, and the vampire took a step back. Murphy smiled. She would be glad to be back to normal, but this was definitely a fascinating power to have for the moment.
