Subclasses:

You draw back and release an imaginary bowstring while aiming at a point you can see within range. Bolts of arrow-shaped lightning shoot from the imaginary bow, and each creature within 20 feet of that point must make a Dexterity saving throw. On a failed save, a creature takes 2d8 lightning damage and is incapacitated until the end of its next turn. On a successful save, a creature takes half as much damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
