Swarm of Insects

Swarming, biting locusts fill a 20-foot-cone in front of you. When the area appears, each creature in it must make a Constitution saving throw. A creature takes 3d10 piercing 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 6th level or higher, the damage increases by 1d10 for each slot level above 5th.
