When a creature that you can see within 30 feet of yourself makes an attack roll, you can take a Reaction to impose Disadvantage on the attack roll, causing light to flare before it hits or misses. You can use this feature a number of times equal to your Wisdom modifier (minimum of once). You regain all expended uses when you finish a Long Rest.
Level 6: Improved Warding Flare
You regain all expended uses of your Warding Flare when you finish a Short or Long Rest.
In addition, whenever you use Warding Flare, you can give the target of the triggering attack a number of Temporary Hit Points equal to 2d6 plus your Wisdom modifier.
(Holy symbol) 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.
