I think that this spell has a 5 sqm range and not 4.
I think this spell is kind of useless, but you can use it between level 55 ~ 80, until you can use the Strong Energy Strike, stronger than Lightning and the same mana cost.
The only drawback is the range decrease of 4 to 3, but its not big deal.

It's probably part of the high level spell rotation. Its 8-second cooldown is not shared between all attack spells, just that spell, so you can do ultimate ES > strong ES > lightning > ES > strong ES > lightning > ES > strong ES > ... > ultimate ES. -- Sixorish 05:16, August 6, 2011 (UTC)
