Peace Domain (5e Subclass)
From D&D Wiki
The Pacifist Domain focuses on harnessing the calm and peaceful energies of nature, dispelling conflicts and being a constant advocate of peace. The gods and goddesses of pacifism promote peace above all else, acting as the polar opposite of the War Domain.
Many non-evil deities claim influence over this domain, including Eldath, Milil, Rao, Majare, Hestia, and Hathor.
|Clerics of peace venerate the ideal of harmony.|
|1st||charm person, sleep|

|9th||hold monster, wall of force|
Acolyte of Peace
At 1st level, you gain the friends cantrip if you don’t already know it. You also gain proficiency in the Persuasion skill.
When you cast the friends cantrip, the target no longer realizes that you used magic to influence its mood, and therefore does not automatically become hostile to you.
Channel Divinity: Cease Conflict
Starting at 2nd level, you can use your Channel Divinity to diffuse a situation.
As an action, you present your holy symbol and evoke calming energy to hostile creatures. Each hostile creature within 30 feet of you must make a Wisdom saving throw against your spell save DC with disadvantage. On a failed saving throw, a creature becomes indifferent towards creatures of your choice that it is hostile toward. This indifference ends if the target is attacked or harmed by a spell or if it witnesses any of its friends being harmed. Even if some creatures succeed on the saving throw, they may still cease hostilities if many of their allies failed the saving throw, unless the DM rules otherwise.
Aura of Sanctuary
At 6th level, you can cease attacks against you as long as you cease your own. At the end of every long rest, you gain the effect of a sanctuary spell that lasts until the start of your next long rest (the spell can end early as normal).
At 8th level, when you cast a healing spell on a creature, they receive the maximum amount of healing and gain the effects of shield of faith for 1 minute.
Avatar of Pacification
At 17th level, you can cast the command spell as a 9th level spell without expending a spell slot. When you cast the spell in this manner, the targets have disadvantage on the saving throw.
