Mastery is a mechanic and stat introduced in patch 4.0.1. Each specialization has its own Mastery, offering benefits appropriate to that spec's role and abilities. Masteries' effects vary, increasing certain types of damage dealt, providing bonus DoT or HoT effects, or even generating free extra melee or spell attacks. Mastery is available at level 10.
Mastery also refers to the secondary stat rating, found on the character sheet. Like other ratings this can be increased by gear with mastery rating on it. Numerous enhancements such as enchantments and gems also increase mastery rating. Mastery stat rating is unique as the effect of it depends both on the player's level and the specific mastery associated with their spec, with each mastery having a different amount of rating required to increase its effects. For example, a warlock that changes from affliction to demonology will see a decrease in both their base mastery value and mastery gained from rating, as it takes more mastery rating to increase than it does for .
Mastery benefits are measured in percentages, whether in terms of a fixed improvement, the size of a bonus effect, or a proc chance. Each mastery has a base percentage value; the mastery stat increases this by a varying amount depending on spec and level. Even characters with no mastery stat rating will therefore benefit from their Mastery.
In terms of stat weighting, the value of mastery depends on the effect it grants the player, as well as the effect of mastery rating on the spec's mastery.
In addition to the character sheet, masteries are also found in the Spellbook under each specialization tab, allowing players to view their other masteries.
Below is a list of all Masteries, and the classes and specs to which they belong. Listed under 'Base effect' are the base percentage benefits granted to players regardless of their mastery stat. 'Rating per 1%' is the mastery rating required at level 60 to gain an additional 1% effect for that mastery's X value only (the displayed mastery value in the paper doll frame). At lower levels, smaller amounts of mastery rating are required to gain the same benefit. Both base effects and ratios are often very specific and are sometimes difficult to determine precisely.

- Patch 5.0.4 (2012-08-28): Mastery is no longer found as mastery rating or measured in points. Gear and items that previously granted 'mastery rating' now simply grant 'mastery', and mastery is now converted directly into a percentage bonus without being measured in points. Accordingly, there is no longer a standard rate of conversion for mastery.
