Shock Pulse

Shock Pulse is a Lightning spell used by s in Diablo III. It is a remake of the classic spell Charged Bolt.

In-game
Shock Pulse releases 3 slow, erratically moving sparks, each dealing Lightning damage to a single enemy. It counts as a Signature Spell and therefore costs no Arcane Power to cast. There is no limit on how many pulses can be summoned at a time, but sparks can only travel 40 yards. Even though the sparks move randomly, they do fly in the direction the spell is cast, spreading within a cone no wider than 90 degrees.

Like Charged Bolt, all variants of Shock Pulse are most effective against large numbers of enemies or against single massive foes, when accuracy is not critical.

Runes

 * Explosive Bolts: damage type turns to Cold. Enemies killed by the bolts explode for 184% damage as Cold, 10 yard range.
 * Fire Bolts: damage type turns to Fire, damage increased to 274%.
 * Piercing Orb: fires one orb instead of three pulses, which moves in more or less straignt path and for greater distance (up to 80 yards), hitting for 214% damage, piercing through enemies.
 * Power Affinity: each enemy hit awards 2 Arcane Power.
 * Living Lightning: releases one, very slow-moving lightning apparition that shocks nearby foes for 165% damage per tick, moving in straight path roughly 20 yards and piercing through enemies.
