Inscription is a profession which was introduced in Patch 3.0.2. Inscription will allow players to augment the cooldown, damage, or mechanics (stun, knockback, DoT, HoT, etc.) of a spell. It will have two aspects: augmentation of abilities and spells with the creation of a new type of item ("scrolls", for example, from ink, parchment, and other reagents).[1] Every player will get a new spell book page to which they can add six glyphs — currently, three major and three minor.
A sub-skill called Milling will accompany Inscription that will produce reagents (pigments) from herbs similar to how the Prospecting sub-skill of Jewelcrafting works.
Inscribing abilities for other characters will involve the creation of Inscription-based scrolls which can be traded, bought, or sold at the auction house in the same manner as other items.[2]
Scribes[3][4] will also be able to create Vellum for enchanters to put their enchants on, this will enable enchanting scrolls to be traded, and sold on the auction house.
Those who don't purchase any expansion will be able to use items created by a scribe, though only those who buy the The Burning Crusade expansion will be able to get the profession and only those who buy the Wrath of the Lich King expansion will be able to level it beyond 375.[5]
