This spell shoots an bolt of electricity in order to do damage. Damage is 1d8 per Effect level of the spell. All within a swath 5' wide and 25' long in front of the caster are affected. The caster may limit range voluntarily at no cost, or extend it with additional levels (which do not add damage). If a victim makes a save vs. Endurance, damage is halved. Armor and shields are ineffective, but protective devices or spells may work.
Area of effect can be increased by doubling either the length or the width of the swath, but the width may not exceed 10'.
