Glyph of Compression

The glyph of compression, when drawn, can be used to compress magic. Draw the glyph, imbue it with magic, and it will compress it into a physical 1x1 cube. You can do this as much times as you want, but each time you do, it will get more and more unstable. Too much magic, and all of your magic will be absorbed, and you will die. The glyph will also explode. If used as a language glyph, defines "Crush", "Small", or just "Compress"
