Oathbreaker Reborn seeks to provide a balanced and fully-realized representation of the class fantasy of a dark, corrupted knight. I've endeavoured to remain true to the original vision while refining aspects I consider lacking, adding internal synergy, and maximizing flavour to provide a, hopefully, more fun experience. Below, you can find a full list of changes to the subclass. If something isn't mentioned, then it hasn't been changed.

They must make a Charisma Saving Throw against your Spell Save DC. If they fail, attacks against them have Advantage.

Cannot be used on a creature that's CR is equal to or higher than your Paladin level. This ability can be used once per short rest.

Level 7: Baneful Contempt

Once per Long Rest, as a bonus action, surround yourself with an Aura of Gloom in a 20ft radius. All light in the aura is snuffed out. Target creatures within range must make a Wisdom Saving Throw against your Spell Save DC or become frightened. Frightened enemies who start their turn in the aura take 4d10 Psychic Damage. Enemies who rely on sight have Disadvantage on Attack Rolls against creatures inside the aura. Enemies in the aura feel the full force of your Spiteful Suffering. This aura lasts one minute, or until you dismiss it as a bonus action.
