In addition to its significant direct damage (which is instant cast and does not reset the shaman's melee attack), frost shock also snares the target. In PvE, it's useful against runners, slowing their retreat if the shock doesn't kill them outright. It can also be used for kiting high level mobs in certain raid situations. Against ranged opponents (in PvP, casters and hunters), the shaman can use this power to stay up close to use melee. Against melee classes like warriors and rogues, shamans use this ability to maintain their distance.
Concussion increases its damage by 1, 2, 3, 4, or 5%.
Reverberation reduces the cooldown of all Shock spells by 0.2, 0.4, 0.6, 0.8 or 1 second.
Elemental Fury increases its critical strike damage by 100%.
Notes[]
Frost Shock gains 40.71% of the caster's Spell Damage.
In addition to significant base damage, Frost Shock's snare can be maintained indefinitely (so long as the caster has enough mana to keep it up), making it one of the most powerful snares in the game.
Patch Changes[]
Patch 1.6.0 (patch date:2005-07-12): Targets that are immune to movement slowing effects will no longer be affected by Frost Shock's movement slowing effect. Damage will still be caused.
Patch 1.4.0 (patch date:2005-05-05): Now subject to diminishing returns in PvP. This is considered a slowing effect.
