[Espy]

Annoyed at being too slow again, Espy knew she couldn't have this fight drag on for too long. She took her second and last dagger from her belt and sliced open her left palm. Blood was a powerful, if taxing, catalyst. Clenching the dagger in between her teeth, she splattered the blood into a rough triangle onto the sand, pointing towards the man, and, hoping she would have enough time and energy left, formed another triangle facing the other direction, with both hands and feet.

The salt and sand that went into her wounds stung, but this really was no time to pay attention to that...

Espy pumped most of the last reserves of her energy into the ground, waiting for the volcanic explosion of fire and earth to erupt at the man's feet.

((That one transmutation takes a huge shitload of energy and some time. I'd suggest you do something about Espy while she's stuck casting it.))
