You present your holy symbol and speak a prayer censuring the undead. Each undead that can see or hear you within 30 feet of you must make a Wisdom saving throw. If the creature fails its saving throw, it is turned until it takes any damage.
A turned creature must spend its turns trying to move as far away from you as it can, and it can't willingly move to a space within 30 feet of you. It also can't take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there's nowhere to move, the creature can use the Dodge action.
Starting at 2nd level, you can use your Channel Divinity to harness sunlight, banishing darkness and dealing radiant damage to your foes.
Presenting a holy symbol, any magical darkness within 30 feet of you is dispelled. Additionally, each hostile creature within 30 feet of you must make a Constitution saving throw. A creature takes radiant damage equal to 2d10 + your cleric level on a failed saving throw, and half as much damage on a successful one. A creature that has total cover from you is not affected.
At 1st-Level, you can interpose divine light between yourself and an attacking enemy. When you are attacked by a creature within 30 feet of you that you can see, you can use your reaction to impose disadvantage on the attack roll, causing light to flare before the attacker before it hits or misses. An attacker that can't be blinded is immune to this feature.
You can use this feature a number of times equal to your Wisdom modifier (a minimum of once). You regain all expended uses when you finish a long rest.
Improved Warding Flare: Starting at 6th level, you can also use your Warding Flare feature when a creature that you can see within 30 feet of you attacks a creature other than you.
At 2nd level, you can expend your Channel Divinity to fuel your speels. As a Bonus Action, you touch your holy symbol, utter a prayer and regain 1 expended speel slot, the level of which can be no higher than half your Proficiency bonus (rounded up).
The number of times you can use this feature is based on the level you've reached in this class: 2nd level once
Starting at 5th level, when an undead fails its saving throw against Turn Undead feature, the creature is instantly destroyed if its challenge rating is at or below a certain threshold, as shown in the Destroy Undead table.
