Explosive Cantrip
Once on each of your turns, when you deal Fire damage to a creature with a Warmage cantrip, you can create an explosion in a 5-foot Emanation originating from the target. Each creature other than the target and yourself within the Emanation makes a Dexterity saving throw against your spell save DC, taking half the Fire damage rolled on a failed save, or no damage on a successful one.
