Water Domain

https://www.dndbeyond.com/characters/subclasses/550-water-domain

Deities of water, such as Kind, Nyana, Fennan, Dovlous and Floull value ideals of purity, vitality, serenity, flexibility, and perseverance. Clerics of such deities seek to protect bodies of water and the communities around them. They might hunt monstrosities that corrupt and taint sources of water, or work to bring water to communities in need of it.

Bonus Cantrips
When you choose this domain at 1st level you gain the shape water and ray of frost cantrips. For you, these cantrips count as cleric cantrips.
Divine Dew
Also at first level, you can conjure blessed water to improve your vitality. As a bonus action, you can grant yourself or a creature you can see within 30 feet temporary hit points equal to twice your cleric level. These hit points last up to 1 hour.
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.
Channel Divinity: Misty Shroud
Starting at 2nd level, you can use your Channel Divinity to cloak yourself and allies in a protective mist.
As an action, you present your holy symbol, and a cold fog swirls around you for 1 round. Friendly creatures within 30 feet of you may immediately use a reaction to move up to half of their speed. Hostile creatures within 30 feet of you are unable to take reactions for the duration. The fog spreads around corners.
Blessings of Water
Starting at 6th level, you can protect yourself and allies from fire and acid with a veil of water.
When a creature, including yourself, gains temporary hit points from a spell you cast, or a Cleric class feature you use, that creature also gains resistance to fire and acid damage while any of the temporary hit points remain.
Potent Spellcasting
Starting at 8th level, you add your Wisdom modifier to the damage you deal with any cleric cantrip.
Warding Rains
Starting at 17th level, you can use your action to conjure a divine rain that surrounds you in a 20-foot radius for 1 minute or until you dismiss it with another action. You and friendly creatures within the rain gain a +2 bonus to saving throws.
Unprotected flames in the area are doused.
