Feyd knew he had the upper hand of not needing to reload his weapon, so he kept peppering the cover that the girl was behind with wisps of fire. He wasn't really sure what he was going to do next, but that seemed irrelevant. She had been shooting back, but it was mostly panicky blind fire in between fireballs, and it wasn't really all that worrying. Feyd thought he could probably set the entire building on fire to flush her out, but that seemed a bit too psychopath-y for his liking, and he also wasn't Micheal Caine chasing a jewel thief. He kept peppering her cover but took a second to concentrate and send one huge, cover erasing ball of fire across the roof. It focused it until it was about the size of an average size sedan and hurled it across the roof. As soon as the fire wasn't under his control anymore, the heat of it burned most of the hair off his exposed chest and legs. He didn't care how the girl at the other end of the roof reacted to the fireball, and knew that she'd be too busy diving out of the way to get any pot shots off at him. He ran and boosted himself across the gap to the next roof and kept sprinting, ignoring the constant pain in his chest.
