As a Magic action, you present your Holy Symbol and expend a use of your Channel Divinity to emit a flash of light in a 30-foot Emanation originating from yourself. Any magical Darkness—such as that created by the Darkness spell—in that area is dispelled. Additionally, each creature of your choice in that area must make a Constitution saving throw, taking Radiant damage equal to 2d10 plus your Cleric level on a failed save or half as much damage on a successful one.
