Inscription is a new profession being added to World of Warcraft in the Wrath of the Lich King expansion. It allows players to create glyphs and scrolls for themselves and others. Glyphs permanently enhance a character's spells and abilities. Scrolls allow you to cast temporary buffs.
So far, Inscription allows a player to create the following:
1)Inks from Pigments, used as Reagents in other Inscription recipes.
2)Create scrolls for enchanters, allowing them to sell their enchants in the Auction House(Example). Scrolls that increase stats
3)Runes that can be applied to a player's Glyph Interface to boost spell effects or make cosmetic changes.
4)Runewords which can be applied to pieces of armor as a form of temporary enchant. Runes of Power that act as offensive/damage spells, consuming Inscription-based Reagents (like Inks).
5)Scrolls of Recall that function similar to Hearthstones, but are like the Engineering transporter where it has unpredictable results. (IE a hearth is set to Shattrath and a Scroll of Recall will take a person to Gadgetzen)
6)Various Card items.
For the most part, Inscription relies on Herbalism as its gathering Profession counterpart. In order to produce Inks, a player makes use of the Inscription ability Milling, which consumes 5 herbs of the same type and creates various Pigments, depending on the type of herbs that were Milled, similar to a Jewelcrafter's Prospecting ability. Herbs now show the Inscription skill level needed to mill that particular herb on their in-game tooltip, and the types of herb needed to make each pigment is in the pigment tooltip in the Inscription Interface.
Inscriptions also gives players the ability Decipher along with Milling, which allow the deciphering of strange and mysterious writing. Currently the goal of this spell is unknown, although it may be similar to an Enchanter's Disenchant ability.
As we have mentioned above, all players access to Glyphs and the Glyph Interface. There is no level requirement to use the Glyph Interface, though individual Glyphs may have level or spell rank requirements. Most Glyphs created through Inscription can be traded or sold, though there may be some Inscriptionist-only Glyphs, similar to the epic Gems that may only be used by Jewelcrafters. Glyphs stack in your inventory up to 5 per stack.
Glyph consists of major Glyph and minor Glyph.
Major Glyphs offer major upgrades to spells. Examples that have been given are the addition of stuns or DoTs to spells, increased damage, or knockbacks.
Minor Glyphs furnish small upgrades, or cosmetic improvements. Examples that have been given are the removal of reagent requirements from spells, lowering spell costs, or changing spell graphics.
On the Glyph Interface, the larger circles with gold borders around them are for placement of Major Glyphs and the smaller circles are for Minor Glyphs.
When a player make uses of a Glyph in their inventory, the Glyph item is destroyed and its inscription effect is placed in one of the appropriate slots.
