Eerongal
Her blow lands as intended, glancing down your back, but leaves a shallow cut a few inches away from your spine. Way too close.
She starts to circle you, but, as you anticipated, her attention is on the glowing hammer. Expected, she charges straight at you again, but, unexpected, is yet another burst of speed. Not as frightening as when she got behind you, but still difficult to track. Her blade, previously glowing green, now glows blue.
A number of things happen very fast. She dives in toward you and you strike with your hammer, shifting just enough to take the force of the blow on her armor. The surge of stunning energy you expect doesn't happen, seeming to dissipate. Whatever this burst of speed is, your stun doesn't faze it. As she gets inside your defenses with this clever move, you use your hidden knife, hoping it'll be enough to stop her.
The blow takes you in the side, leaving a nasty dent in the armor. She staggers away, a knife protruding from her chest, bleeding freely. Her paling face seems confident, somehow.
She collapses, a flash of light obscuring her as she hits the ground. When the light clears, you don't see the unconscious body of your opponent's baseline, but a small girl.
The girl rolls up onto her feet, her posture falling into a pout. Her face is familiar enough to be recognized as your opponent somehow changed into a child.
"That wasn't very nice."
