The new beta testing has brought many changes and improvements for the wrath of the Lich King, including the important inscription system for players.
Now let's have some looks at the Glyph interface in the latest patch.
All players have 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.
Each player can add up to 6 Glyphs to their interface: 3 Greater Glyphs and 3 Lesser/Minor Glyphs.
Greater Glyphs provide major upgrades to spells. Examples that have been given are the addition of stuns or DoTs to spells, increased damage, or knockbacks.
Lesser Glyphs provide upgrades to spells similar to Greater Glyphs, but are not as powerful.
Minor Glyphs provide 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 Greater Glyphs and the smaller circles are for Lesser or Minor Glyphs.
Glyph Mastery is developed to unlock an additional glyph. It is an ability that is linked to Inscription, but of a currently unknown origin, provides access to an additional Glyph.
Different players will have their different opinions towards the Glyph improvements in the latest patch. However, as a conclusion, the game and its develops will ultimatley followe the mainstream and perfected the game.
