World of Warcraft/Professions/Inscription

For inscription a character mills plants into pigments to produce inks, and with the help of parchments available from a vendor near an inscription trainer, creates glyphs or scrolls. Glyphs can be inserted into the sockets designed for them. These sockets can be accessed by opening the spellbook and clicking on glyphs tab. To insert a glyph one has to be at a Lexicon of Power (a sort of floating, glowing book), which can be found near any inscription trainer. Scrolls typically can be used to provide a temporary buff to some attribute.

Glyphs are class-specific. They enhance the abilities a class has by increasing damage, making effects last longer and the likes. There are major and minor glyphs. Major Glyphs are glyphs which modify the mana cost, the cooldown, the duration of effect, or add an effect to a spell or ability. Minor Glyphs can be used to enhance or modify a spell's effect or cost, but at a much lower degree than Major Glyphs.
