Manifesto of Unity

From 1st Level in this Domain, you gain Proficiency in Insight; Persuasion; and Intimidation.

Lead by Example

From 1st Level in this Domain, you have the ability to select a number of allies you can see equal to your Proficiency Bonus, and create a bond with them. While this bond is active, all bonded targets add an additional d4 to any roll they make that copies an Action which they have seen you take on your previous turn. The bond remains active until your next long rest, whereupon your available uses are replenished.

Channel Divinity: Resolve Conflict

Starting at 2nd Level, you can use your Channel Divinity to calm disputes that hostile entities have with you and your allies. 

As an Action, display your holy symbol or invoke the name of your chosen deity. Any enemy within 30ft who can see you must make a Wisdom saving throw against your Spell Save DC. On a failure, the behaviour of said enemy changes from hostile to neutral towards you and anyone you consider an ally. If the enemy rolls a Natural 1, they are Charmed by you. The effect lasts for 1 minute or else until you or an ally deals damage to said enemy.

Channel Divinity: Reward Disciple

At 6th Level, when an entity following a command or suggestion that you have given fails a roll, you can use a Reaction if you have one available to grant them a re-roll. If they succeed on their re-roll, both the target and yourself gain temporary hit points equal to 1 d8 + your Proficiency Bonus.

Natural Authority

At 8th Level if a target fails a saving throw against you during an encounter, they have Disadvantage on all other saving throws against you for the remainder of the encounter.

Sphere of Influence

When you reach 17th Level, you can use an Action once per short rest to impose a 60ft radius around yourself for 1 minute. While this effect is active, any other entity within this sphere is Immune to being Charmed or Frightened by anyone other than you.
