Lightning Spells

Lightning Spells are powerful elemental spells used to summon bolts of lightning. They are closely related to wind spells.

History
Merlin first cast a lightning spell on the Isle of the Blessed, where his powers were naturally heightened due to being a creature of the Old Religion. After discovering Nimueh had killed Gaius, Merlin mastered the power over life and death and used a nonverbal spell to gather a storm over her head. He then directed lightning to strike her, trading her life for Gaius's and restoring balance to the world (Le Morte d'Arthur).

During the Battle of Camlann, Morgana cast a nonverbal lightning spell to kill the knights around Mordred. The spell was powerful enough to strike down five men at once.

Merlin also conjured lightning during the battle. Disguised as Dragoon, he used his staff to fire destructive bolts from a cliff overlooking the plain. He decimated Morgana's army, killing half a dozen men with each bolt, and even struck the witch herself, knocking her unconscious (The Diamond of the Day).
