Hits magically enhanced slavers

...only to find three slaver ponies racing along the side of my boxcar, passing me! Somewhere, a slaver unicorn was aiding them with spells! A magic glow held their hooves to the side of the moving train. “Luna rape you with her horn!” I growled, feeling incensed at the magical trickery, and swung about the assault rifle, firing into their hindquarters, flanks and necks as they raced down the next boxcar towards the passenger car. Two ponies screamed as they fell from the train, mortally wounded, one breaking his neck in the fall; but the third made it to the gap between cars before I could bring my weapon to bear on him.
