Cone of Lightning

Lightning which electrifies the air erupts from your hands. Each creature in a 60-foot cone must make a Constitution saving throw. A creature takes 8d8 lighting damage on a failed save, or half as much damage on a successful one.

A creature that failed the saving throw is paralyzed until the beginning of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
