Swirling Lights

You create a swirling pattern of lights in the air at a point within range. All creatures within a 20ft. sphere must make a Dexterity saving throw or fall prone. Any creature who fails their saving throw also becomes dizzy until the end of that turn. When their turn starts they move in a random direction determined by a d8. If they attempt to make an attack roll they must make another Dexterity saving throw or automatically miss any attack rolls.
