Diabolical Domain

The Diabolical Domain focuses on the shivering negative energy — one of the darker forces of the universe — that corrupts all life. The diabolical demons and devils of the multiverse obstruct the divine through making deals the sick and wounded, corrupting the greedy, and driving away the forces of good. Any demon or devil can claim influence over this domain.

When you choose this domain at 1st level, you gain resistance to fire.

You can speak, read, and write Infernal and Abyssal. Additionally, whenever you make a Charisma check when interacting with Devil and Demons, your Proficiency Bonus is doubled if it applies to the check.

Channel Divinity: Corrupt Life

Starting at 2nd level, you can use Channel Divinity to destroy another creature's life force by when casting a spell that requires an attack roll.

Infernal Wrath

Starting at 17th level, enemies you designate for destruction wilt under the combined efforts of you and your allies. If you deal your Infernal Wrath damage to a creature on your turn, you can damn that creature until the start of your next turn. The next time one of your allies hits the damned creature with an attack, the target also takes 2d8 necrotic damage. When the damned creature dies you gain Soul Coin.
