If the IT guy tried to get out of there, he would be in the line of fire. Perhaps he would try to run when the demon was distracted enough. He hung up the phone an peered over the desk to look at the demon, then ducked again and looked at you. The demon created another one of those black balls and threw it at you, but the IT guy kicked a chair in his direction, making the demon stumble. The ball missed you by a hair. As it flew by you, for a moment you could feel the darkness of oblivion inside it. If that hit, you wouldsimply cease to exist.

Now the demon was really pissed. He disappeared and in the same shimmering fashion he appeared behind you. He held up both hands and in each a ball of darkness began to form. From this position he could throw one at each of you.
