In the Ravenloft setting, priests of Ezra have a mystical connection to the Mists that permeate the landscape. In previous editions, clerics of Ezra have had access to a specific "Mists" domain; this is my attempt to work-up something thematically appropriate for 5e Dungeons & Dragons.
Though much-feared as an unpredictable, mysterious force by the people of the Core, the clerics of Ezra can channel the power of the Mists to help protect the people of the land.
Mists Domain Spells
|entangle, fog cloud|

Channel Divinity: Shield of Mist
Starting at 2nd level, you can use your Channel Divinity to envelop yourself in film of luminous mists. This misty barrier around yourself that lasts for 1 minute, or until you lose your concentration (as if you were concentrating on a spell). While protected by this barrier you have resistance to bludgeoning, piercing, and slashing damage.
Channel Divinity: Guardian of the Mists
At 6th level, when a creature within 30 feet of you is attacked, you can use your reaction to conjure a protective shield of mists around it that grants that creature resistance to bludgeoning, piercing, and slashing damage for 1 minute, using your Channel Divinity.
