A stroke of lightning forming a line 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 6d6 lightning damage on a failed save, or half as much damage on a successful one. A creature wearing metal armor has disadvantage on this saving throw. A creature hit by this spell, and that is wielding a metal weapon, must roll a Strength saving throw. Dexterity can be used if the creature is wielding a Finesse weapon. On a failed saving throw the creature drops the weapon.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 3rd.
