Oath of Purification

Your continued devotion to your god allows you to combat the forces of evil through Holy fire (radiant fire damage). 

*Note*   This subclass is potentially overpowered and revisions will be made to make it less overpowered. I created this subclass for more of a thematic multiclass build where my character wouldn't be hitting max level. Please give feedback on everything (including the name and ability names) if you play test this subclass. As I make revisions, i'll be sure to date the changes. Also, for flavoring, divine smite could be worded as holy smite to stick with the theme, but that's up to you. 

Revisions: 
28Nov2019--Changed wording on a feature. 

Channel Divinity

When you take this oath at 3rd level, you gain the following two Channel Divinity options.

Purifying Strike: You can use your Channel Divinity to imbue your weapon in flames for 1 minute. When you make a melee attack you add 1d12 holy damage. The weapon also emits bright light in a 10 ft radius and dim light 10 ft beyond that. If the weapon is not already magical it becomes magical for the duration.
*Note*  This ability doesn't stack on top of a smite.

Prayer of the Faithful: As a bonus action, you can utter a quick prayer to bolster your allies with your Channel Divinity. Each ally of your choice that can hear you within 30 feet of you gains a bonus to their AC equal  to 1d6+ your charisma modifier and regains equal hit points back. Lasts for 1 minute or until the ally drops to 0 hit points.

Purifying Aura

At 7th level, whenever an ally enters your aura, they gain temporary hit points equal to your charisma modifier. Lasts 1 minute. A short rest reactivates the ability.

Soul of the Purified

Starting at 15th level, when an ally under the effect of your Prayer of the Faithful is attacked, you can use your reaction to impose disadvantage to the attack.

Avenging Angel

At 20th level, you can assume the form of an angelic avenger. Using your action, you undergo a transformation. For 1 hour, you gain the following benefits:

• Wings sprout from your back and grant you a flying speed of 60 feet.
• You emanate an aura of purity in a 30-foot radius. The first time any enemy creature enters the aura or starts its turn there during a battle, the creature takes 6d12 holy damage and must make a Wisdom saving throw or become frightened of you for 1 minute. On a successful save, creature takes half damage.  Attack rolls against the frightened creature have advantage.

Once you use this feature, you can’t use it again until you finish a long rest.
