Murder of Crows

You summon and unleash a murder of deadly crows. Each creature of your choice in a 30-foot Cone originating from you makes a Dexterity saving throw. On a failed save, the target takes 5d6 Force damage and has the Blinded condition. On a successful save, it takes half as much damage only. A Blinded creature repeats the save at the end of each of its turns, ending the effect on itself on a success. The effect also ends if the creature regains any Hit Points. The crows disperse and vanish after they strike.

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 4.
