Dalamar's Lightning Lance

You create a crackling lance of lightning that you hurl at your foes. Make a ranged spell attack against a creature within range. On a hit, the lance deals 3d6 piercing damage from the impact of the strike, and the target must make a Constitution saving throw. A creature takes 7d6 lightning damage on a failed save, or half as much damage on a successful one.

At Higher Levels: When you cast this spell using a spell slot of 5th level, the lightning damage increases by 1d6, and an additional 1d6 for every other level above 5th. When you cast this spell using a 6th level or greater spell slot, you may hurl an additional lightning lance, and yet another at 8th level or higher. All bolts must be aimed at creatures within 30 feet of each other.
