You call upon the power of the wind to summon a small tornado in a 10-foot radius, 40-foot high cylinder area centered on a point within range. The tornado can be moved up to 30 feet as a bonus action on your turn.   Any creature that comes into contact with the tornado must make a Strength saving throw or be thrown outwards from the tornado in a random direction 20 feet away. When it lands, it takes 3d6 bludgeoning damage and is knocked prone. To determine the direction, roll a d8 and assign a direction to each die face. On a successful saving throw, a creature takes half as much damage and is pushed out of the tornado instead, to the closest space possible.
