Avogad's Winds of Vengeance

You touch any willing creature and surround them with a buffeting shroud of supernatural, tornado-force winds. These winds grant the target a fly speed of 60 feet with perfect maneuverability. The winds shield the target from any other wind effects, and form a shell of breathable air around them, allowing them to fly and breathe underwater or in outer space. Ranged weapons (including giant-thrown boulders, siege weapon projectiles, and other massive ranged weapons) passing through the winds are deflected by the winds and automatically miss if they are non-magical and are rolled at disadvantage if they are. Gases and most gaseous breath weapons cannot pass through the winds. If the target of this spell is subject to a dexterity saving throw they make that roll at advantage.

In addition, when a creature hits the target of this spell with a melee attack, the subject of this spell may shape the winds so they lash out at that creature as a reaction. The creature must make a Constitution saving throw or take 6d8 points of bludgeoning damage and be knocked prone (if on the ground). On a failed save, Large-sized or smaller flying creatures are blown away 10 ft instead of knocked prone. On a successful save, the damage is halved and the creature is not knocked prone (or blown away).
