Channel Divinity: Icy Embrace

Starting at 2nd level, you can use your Channel Divinity to add a touch of harsh winters to your spells and abilities.
When you deal cold damage to a creature with a cleric spell of class feature, you can use your reaction to attempt to freeze it with divine will. The creature must make a Fortitude saving throw against your spell save DC. On a failure, the target is restrained for 1 minute. It repeats the saving throw at the end of each of its turns, ending the effect on a success.

Numb to Pain

At 6th level, you gain resistance to cold damage and the DC for concentration checks you make no longer has a minimum of 10.

Blessed Strikes

You are blessed with divine might in battle. Starting at 8th level, once per round, when you would deal damage to a creature with a weapon attack or a cleric cantrip, you may deal an additional 1d8 points of damage of a type appropriate for you domain (see Narrator). At 14th level, the additional damage with weapon attacks increases to 2d8 (cantrips still only deal an additional 1d8).

Relentless Winter

Starting at 17th level, your body can thrive in even the harshest of winters. You gain the following benefits:

• You ignore all of the effects of Fatigue, save for the last level.

• You are coated with a protective frost. When you are hit with a melee attack by an attacker within 5 feet of you, if the attacker doesn't have resistance or immunity to cold damage, its speed is reduced by 15 feet and it has disadvantage on weapon attacks rolls until the end of its next turn.
