This spell gives you the ability to call down lightning to strike your enemies. When you cast this spell, you can immediately call a lightning bolt to strike target opponent within [Long] range, dealing 2d4 energy damage with the [Electricity] descriptor per level you possess to that opponent. A successful Reflex save halves the damage. Until the end of the [Encounter], as a standard action, you can repeat this effect. You may choose a new target each time you repeat the effect.
Choose a weapon the target of your Incantation (who is also the target of this spell) is wielding. Whenever the target creature deals damage with an attack using that weapon, it deals additional energy damage with the [Electricity] descriptor equal to 1d6 per circle you possess in the spellcasting track that grants this spell. Effects and abilities that increase the damage of spells have no effect on this additional damage. This is an [Arming] effect.
