Patron's Parting Gift

Starting at 14th level, your patrons grant you one last boon to use against their counterpart.

Celestial: When you damage a target you bring their the judgment of the heavens down upon them. The target takes 10d10 radiant damage as their sins begin to eat away at them. This damage is doubled against undead and fiends. Additionally if the target dies from this damage the creature disintegrates emitting holy light healing creatures within 30 feet for the damage. The healing does not effect Undead or Fiends.

Demon when you make a hit a melee attack against a target you may attempt to forcibly demonize them. As the demon blood sets in the creature takes 10d10 psychic damage. If the target is a fiend it takes no damage. If the creature dies from the damage you may use your bonus to cause the creature to explode dealing 10d10 fire damage on a dexterity saving throw. If you do not use the Bonus action and the damage leaves the Creature alive they must make a Constitution Saving throw or be forcibly demonized, changing them into a Fiend of half your level in CR which you do not control.

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