A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an illusionary explosion of flame. Each creature of your choice within a 20-foot radius sphere centered on that point must make a Wisdom saving throw. A target takes 6d6 psychic damage on a failed save. A creature that passes their saves realizes the fire is illusionary and takes no damage. You can make the illusory effect an explosion of ice, lightning, or pure force energy.
