I'm at the part with Wilbur, and I'm stuck. So far I've swept up the hall by using the automation spell on the broom from the display case, but I can't get it to stop sweeping. I also got the fireplace network travel powder after I distracted the headmaster with a kobold. In my inventory I have a bellows filled with stinky gas from the classroom plant, a nibbled notepad, a magic wand, loose pages from a book, gold coins from the fishtank, a fishbone and thread that have combined into a sewing needle, a yellowed design drawing, a magic slate, fireplace powder, an automation spell, an open spell, a fairy spell, and a keyring. What do I do now? I still have to get rid of the kobolds, get rid of the cobwebs and stop the sweeping broom. I also have to get to the library, but I don't know how to start a fire. Any suggestions would be greatly appreciated.
