Frost Domain

Those who follow the gods of frost are generally found in the north, where the winters are brutal, and the cold kills more than any blade or spell. This harsh nature is reflected in the gods that represent this domain: Ymir, Auril, and Thrym. Each of these deities is wicked and mischievous, out to make sentient life miserable or wipe it out entirely. However, some gods' temples shelter the weak and provide protection from the cold. These deities are few and far between, but the most notable of them are Bahamut and Skadi. As a cleric of the Frost Domain, will you aid your fellow man or leave him out in the cold?

Chilling Aura

At the 1st level, the ambient air temperature within 10 ft. of you drops by 5 degrees, down to a minimum of 32 degrees Fahrenheit. When you deal cold damage to a creature within 10 ft. of you, you can choose to deal additional cold damage equal to your cleric level to the affected creature(s).

Channel Divinity: Cold Snap

Starting at 2nd level, you can use your Channel Divinity to instantly freeze opponents.

As an action, you present your holy symbol and touch one creature, causing ice crystals to form on their body. That creature must succeed on a Constitution saving throw against your cleric spell save DC or become Incapacitated. You can end this effect as a bonus action. The affected creature can make a Constitution save at the end of each of its turns to end this effect.

Winter's Blood

At the 6th level, your god protects you from the harshness of winter's bite. You gain resistance to cold damage. When you finish a long rest, you can choose up to 8 people (including yourself). Those people are unaffected by difficult terrain caused by snow or ice, even if it was caused by magic. In addition, those people can tolerate temperatures as low as -100 degrees Fahrenheit.

Potent Spellcasting

Starting at the 8th level, you add your Wisdom modifier to the damage yo deal with any cleric cantrip.

Winter's Wrath

Starting at the 17th level, you gain immunity to cold damage. Also, you can cast the spells from your domain spell list at their lowest levels without expending a spell slot. You can cast each spell from your domain spell list in this manner once. When you do so, you cannot cast that spell again in this manner until you finish a long rest.
