Numbing her arm with several salves and spells, she took a deep breath before she uttered the spell. Instantly, pain was shooting through her arm. The dark magic was fighting the spell, tearing through healthy skin. Hermione muffled her screams, trying to focus and hold her arm still.

It was enough for the dark magic to shoot to the other side and it felt as if her arm was being torn off from the inside out.
