Shock

A shock is a sudden effect, but not limited to the classical electric shock. There are many different shocks in the game, all of them represent a certain element and damage caused by it. All shocks deal instant direct damage but are usually not very mana-efficient and have a shared cooldown.

Shaman
The three Shock spells, which share a cooldown, are the main source of magic damage for the shaman on close range:


 * Flame Shock: Instant Fire damage and DOT.
 * Frost Shock: Instant Frost damage plus a slow effect.
 * Earth Shock: Instant Nature damage, plus it reduces the target's attack speed by 10% for 8 seconds.

The spell Wind Shear used to be known as the fourth Shock, Wind Shock.

Paladin
Paladins have a unique shock for both offensive and defensive situations:


 * Holy Shock: Either heals a friendly target or damages a hostile one.

Others
There are other Shock spells that cannot be used by players but mobs or NPCs might have that ability as a part of its main damage sources.


 * Shadow Shock: Powerful direct Shadow damage. Used by certain Necromancers, Witch Doctors and Duskwing.
 * Lightning Shock: Direct Nature damage (lightning shaped). Used by Forged Iron Troggs.
 * Arcane Shock: Instant Arcane damage and DOT. Used by Vexallus and Kiggler the Crazed.
