Mastery: Elemental Overload

Mastery: Elemental Overload is the mastery for Elemental Shaman, improved by the mastery secondary stat.

Specialization

 * Rank 2 of this mastery, available at level 78, allows it to affect Lava Burst, as well as Icefury (shaman talent) and Elemental Blast if the Shaman is talented into these abilities.

Talents

 * Stormkeeper - Causes the next two casts of Lightning Bolt or Chain Lightning to trigger an elemental overload on every target struck.
 * Surge of Power - Casting Earth Shock allows the next Lightning Bolt to trigger an elemental overload 1 to 3 additional times.
 * Totem Mastery - The Storm Totem from this talent increases the chance for Lightning Bolt and Chain Lightning to trigger an elemental overload by 5%.
 * Unlimited Power - Grants a stacking buff for 2% Haste for 10 seconds each time an elemental overload occurs. The buff's duration is not refreshed when a stack is gained.

Trivia

 * This is the first and only mastery in game that is available before level 78. Thus, elemental is the only specialization that gains any benefit from mastery rating prior to level 78.
 * This is the first and only mastery that has an additional rank.
 * This is the first and only mastery to be reintroduced after being removed as one.
 * Elemental Overload was the mastery for elemental shaman prior to being redesigned and replaced in Patch 6.0.2.
 * Prior to the introduction of masteries, the ability for certain Shaman spells to "overload" has existed in game since Patch 2.0.1 added Lightning Overload.
