Choreographing magic

Choreographing the fight. . . always fun when you are dealing with magic. At least the two sides are, in fact, two people. At least at first.

But one can turn invisible and fly. The other has knowledge based powers that may nullify the first -- perhaps I need to define them more clearly.

The first one does have the advantage that he is there to rescue people with more magic. Which only complicates my task further.
