The IT guy turned around and saw the demon. "Wow." He ducked just in time to avoid the ball of blackness, which hit the computer instead, swzllowing it whole. The demon growled and turned his attention to you. "Stay out of it, witch!" He snarled and looked again at the IT guy who was now scurrying behind a desk for cover. It was still a few meters (10 feet) towards the exit but the demon had a clear view of the door. If he tried to go for that he would be an easy target. Meanwhile the demon readied another ball of black smoke and started to make his way towards the IT guy, who was getting his phone.
