"Depict a warrior woman in the midst of casting a powerful speed spell. She is moving so fast that she leaves a trail of translucent copies of herself, creating a sense of motion and blurred action. Her armor and weapon glint in the light as she races forward, with each afterimage gradually fading into transparency. The copies should mirror her movements, giving an impression of rapid displacement, while the environment behind her blurs with the intensity of her speed. The overall effect should feel dynamic, with a mystical, almost ethereal energy."
