Beginning at 1st level, a divine blessing grants you the ability to see more clearly in dark and dim conditions. You gain Darkvision out to a range of 18m.

When you reach 6th level, you gain Darkvision out to a range of 37m. 

At 8th level, you can see normally in both magical and nonmagical darkness.

Finally, at 17th level, your eyes are able to see the truth hiding within darkness. You gain the ability to call upon the powers of your deity to grant yourself truesight within 37m of you. Your Truesight only functions while in conditions of magical or nonmagical darkness.

Once you have used this feature, you cannot use it again until you have completed a Long Rest.

At 1st level, you can create a ward of divine shadows to conceal yourself from an attacking enemy. When attacked by a creature you can see within 9m of you, you can use your Reaction to impose Disadvantage on the Attack Roll, as shadows envelop your form. An attacker that can’t be Blinded is immune to this feature.

Starting at 2nd level, you can use your Channel Divinity to harness the powers of night, clouding the vision of your foes in a shroud of darkness.
As an Action, you present your holy symbol causing any source of mundane or magical light within 9m of you to be extinguished. Additionally, each hostile creature within 9m of you must make a Constitution Saving Throw. A creature who fails the Saving Throw is Blinded for a number of rounds equal to your Cleric level. A creature Blinded in this way gets a new Saving Throw at the end of each of its turns to remove the effect.

At 6th level, you can use your Ward of Shadows feature whenever a creature you can see within 9m of you attacks a creature besides yourself.

When you reach 8th level, you gain mastery over magical sleep. When you cast the Sleep spell, add an additional 14 hit points to determine how many hit points of creatures the spell can affect.

Additionally, any creature you put to sleep using this spell cannot be woken until the start of your next turn. Otherwise, the Sleep spell acts as normal.

Starting at 17th level, you can use your Action to activate a supernatural aura of deep night. It lasts for 1 minute, or until you dismiss it using another Action. You emit heavily obscuring darkness in a 9m radius. The darkness and shadows overlap and continually smother existing sources of light.

Enemies within the shadows constantly feel the presence of hungry predators watching them, and become Frightened as long as they remain inside the affected area. Enemies in the darkness are both Blinded and Frightened for as long as they remain within its area.

You incant towards a creature, cloaking them in a shadowy veil of darkness and silence. The target gains a +1 bonus to their Armor Class and makes Stealth Checks with Advantage for the duration of the spell.

You create two small stars that orbit you. They twinkle pleasantly, shedding dim light in a 3m radius centered on you. The stars protect you. If a creature hits you with a melee attack, they must make a Wisdom Saving Throw or take 1d8 Radiant damage for each star orbiting you.

Once per round, on your turn, you may use your Action to cause a star to streak toward an enemy, expending it as it explodes in a blinding flash. Make a Ranged Spell Attack against a creature within 37m, dealing 4d8 Radiant damage on a hit. The target must then make a Constitution Saving Throw or be Blinded until the start of your next turn.

The spell ends when its duration expires, you fall unconscious, or you have expended all of your stars.

At Higher Levels. When you cast this spell using a spell slot above 4th level, you create one additional star for every two slot levels above 4th. For each additional star orbiting you, the radius of light centered on you increases by 2m.
