You can compare a glyph as a word in a sentence.
For basic and non powerful spells, you only need one glyph.
Every glyph needs to be \"purified\" before usage, which will create a bond between you and the glyph, making it unpurified if you drop it or trade it.
Purifing will take MUCH longer time in the future (I think about 1-2 hours) because they\'re so powerful.
To get access to more powerful spells you need to combine glyphs in the right order (4 slots). In the near future, if you combine 3 glyphs correctly (like Light, Blue, Brown) and then by misstake add a Dark (which don\'t like Light

) it will backfire and stuff like that (This is taken of own speculations, but I know it will backfire in the future

)
