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 78, and has no effect until that level is reached.
Mastery also refers to the secondary stat, found under Melee, Ranged or Spell on the character sheet. Characters have a base mastery of 0, but this can be increased by gear with mastery on it. Numerous enhancements such as enchantments and gems also increase mastery.
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 small amount, depending on spec and level. Even characters with no mastery bonuses will therefore benefit from their Mastery.
In terms of stat weighting, the value of mastery depends on the effect it grants the player.
Below is a list of all Masteries, and the classes and specs to which they belong. Listed under 'Base effect' is the base percentage benefit granted to players regardless of their mastery stat. Listed under 'Ratio' is the amount of mastery rating required to gain an additional 1% effect (for X values only), at level 120. 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 7.0.3 (2016-07-19): Masteries are now learned at level 78 instead of 80.
- Patch 6.0.2 (2014-10-14): Masteries are no longer found in the Spellbook.
- 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.
- Patch 4.0.1 (2010-10-12): Added.
