Glitch: Walk on walls
During your first "Dark Against The Arts" class, you will learn "Reparo". You will be in a room for testing only when you learn that spell. Do not use Reparo on anything in the room. If you use Reparo to get on the cabinet, when you get back down you will find that you can walk on walls and out of the screen. However, you cannot get any farther and must start from the beginning.
