Explode

As a Creeper Kin, you channel your innate explosive power into a more potent and controlled blast. When you cast this spell, your body releases a powerful explosion centered on yourself. Each creature within a 5-foot radius of you, including yourself, must make a Dexterity saving throw against your spell save (DC 14). A creature takes 4d6 fire damage on a failed save or half as much damage on a successful one.
