Storm Hammer

Storm hammer is an offensive technique that is used to attack enemies in melee combat. Used in tandem with a weapon, storm hammer is a magic technique that imbues a weapon with electricity, adding to the impactive damage.

Electricity crackles through the weapon and can be plainly visable as a light emitting from the weapon. The static can be used to electrocute objects when they come into physical contact with the imbued item. Physical touch is needed when preforming the technique, as such McGregor cannot use it in conjunction with ranged weaponry.

This doesn't only need to be used with a weapon, as seen when McGregor channeled it through a wire fence to illuminate it. Another use for the storm hammer technique is channeling the energy to the palm and increasing the frequency, creating a physical barrier, strong enough to block a sword.
