How could I not, after all you'd shown me? Though it would be difficult to show you how I fight with magic when we are--here. The library, after all, isn't quite the appropriate place to demonstrate combat abilities and mine are a little more difficult to explain. As for my illusions... They are, the most of them, simple simulacrums that disappear at a touch. I am also capable of changing one being into another--though I suspect you would not welcome a demonstration of that without warning.
