Duality Domain

When you find yourself caught between wanting to kill or heal, believe in the faith of the Duality Domain, that way, you can do both.

Duality Shift

Starting at 1st level, you gain the ability to embrace one half of your two-sided soul temporarily. As a bonus action you can choose either a White or Black Soul, gaining benefits depending on the type of soul you chose.

-White Soul: You gain resistance to radiant damage and your alignment becomes Lawful. Also, spells you cast that deal radiant damage ignore resistance to radiant damage. When you take damage from a melee or ranged attack, you can use your reaction to turn your White Soul into a Black Soul.

-Black Soul: You gain resistance to necrotic damage and your alignment becomes Chaotic. Also, spells you cast that deal radiant damage deal necrotic damage instead. When you take damage from a melee or ranged spell, you can use your reaction to turn your Black Soul into a White Soul.

This effect ends when you are reduced to 0 hit points or when you end it as an action.

Channel Divinity: Alignment Burst

Starting at 2nd level, as an action, you present your holy symbol and fire a beam of light at a creature within 30 feet of you. The following effects apply depending on your alignment;

-Lawful: That creature regains 1d10 hit points. If your alignment is Lawful Good, then they regain 2d10 hit points instead.
-Neutral: That creature takes 1d10 less damage from the next attack or spell that hits them. If your alignment is True Neutral, then they take 2d10 less damage instead.
