Hexology Domain

This domain of clerics has specialized in the art of handling curses. Many in this domain believe in stopping the spread of curses by cutting them at the root. This domain is tied to the soul of the world and draws on its faith in its deities to bring peace to that soul. Many in this domain are specialists in their faith and often exhibit the most zealous devotion, as it directly deals with the blight of this world. Many religions bring in Hexoligist when everything stops working the way it should, and believe it to be the misdoings of magic.

Level 3: Curse of Sickening

As a Magic  Bonus action, you present your Holy Symbol and expend a use of your Channel Divinity to curse an enemy and render them weak. As a Magic Action, you can spend a use of your Channel Divinity to give one target disadvantage on all attack rolls and saving throws until the start of your turn. If you or an ally hit before that, you can end it early and deal Cleric level+1d8 in Nec or Rad.

Cursed energy influence

You know how to manipulate curses in two ways other than inflicting them. 

Spitful absorption: You can add the negative energies you inflict into attacks. Once per turn when you deal damage with a spell or attack to a bloodied creature, you deal an extra d4 of necrotic damage

Anti curse: You can max out healing on downed targets

Anti Curse manipulation

When an ally is down to 0 hp, you may have your healing maxed out with any spells or features. Such as 4d4 becomes 16 when your ally is unconscious.

Spiteful Absorption

Once per turn, when you cast a damaging spell or attack a bloodied creature, that creature takes extra necrotic damage equal to a d4

Level 6: Cursed awareness

When you see a target within 30 ft of you, yourself included, you can spend your reaction and half the damage. You can use this feature a number of times equal to your wisdom modifier and regain all uses on a long rest. 

Level 17: Curse Specialist

When a spell you cast is either a necromancy spell that is 5th level or lower or a Hexology domain spell that targets one creature, you can spend your channel Divinity to target a second. If there is a cost, you must pay it for both. 

Level 17: Curse Transformance

When an enemy within 60ft of you dies, you or an ally within 60ft can restore hit points equal to 3 times your cleric level. This is usable once and then can come back with a long rest.
