Glassee

By means of this spell, the wizard is able to make a section of metal, stone, or wood as transparent as glass to his gaze, or even make it into transparent material as explained hereafter. Normally, the glassee spell can make up to 4 inches of metal, 6 inches of stone, and 20 inches of wood transparent. The spell will not work on lead, gold, or platinum. The wizard can opt to make the glassee work only for himself for the duration of the spell, or he can actually make a transparent area, a one-way window, in the material affected. Either case gives a viewing area 3 feet wide by 2 feet high. If a window is created, it has the strength of the original material. The material component of the spell is a small piece of crystal or glass.
