Freeze Them All

I'm a little wizard and A chaser who catches monsters which have escaped from the magical world. The magic I use is ice magic. I can freeze anything just by touching it with a potion. But there is one weakness. Monster can't solve magic on its own, but other monsters can solve it. Anyway Shall we start now? Ah... wait. I have to dress before I leave. I actually just graduated from magic school. I can't go around in training clothes.
