Crow Swarm

You call crows to attack every creature in a 30-foot cube centered on a point you choose within range. Each creature in that area must make a Dexterity saving throw. Constructs aren't effected, and plants and undead make this saving throw with disadvantage. A creature takes 8d8 piercing damage on a failed save, or half as much damage on a successful one.

At higher levels. The spell's damage increases by 1d8 per level above 5th
