This spell works like beam weapons in most FPS games, locking onto a target and bending to keep it in the lightning zone even as the enemy moves around. It can chain to a second target, and during the BlizzCon 2008 demonstration, this spell was seen upgraded with a [[runes|multi-strike skill runeHydra Rune]](named Multistrike before), enabling it to strike additional targets at once. A Viper Rune (named Lethality Rune before) was also shown in conjunction with Electrocute, which caused some enemies to explode in an electric Nova upon death, dealing damage to nearby monsters. This is the same sort of death monsters suffer when they perish from a lightning [[critical hit]].
