You summon an unkindness of ethereal ravens from your fingertip. You target a creature, and the flock flies in a straight line, and is the width and height of a large creature. When the birds impact the first creature in their path, they deal 2d10 slashing damage and 2d8 force damage. The crearture may make a strenght saving throw or be pushed back 5 ft. and be knocked prone. On a success the creature takes half damage and is not moved or knocked prone. Moving against the the flock counts as difficult terrain. A creature affected by the spell is blinded.
For the duratio at the start of your turn, you can use your action to repeat the spell effects on the target, or move the spell to another creature within range. That creature is affected by the spell immediately.
You may expend additional spell slots to make the flock scream with an otherworldy, piercing shriek. This adds an additional 1d8 psychic damage to the spell's damage per spell slot expended.
