The Exorcist

Ascendant. You drawth forth the soul of the wicked, exorcising the demons within.

As a bonus action, you can exorcise the strength of the wicked. The next time you hit a creature with an attack, you deal an extra 2d6 + your proficiency modifier of radiant damage. The damage of the creature’s next attack is reduced by a number equal to the amount of radiant damage that it took from this ability.

You can use this ability once before refreshing it in town using Performing Sacred Rites or Religious Service Downtime actions.

At Higher Levels. The attack deals an extra 1d6 radiant damage when you reach 5th level, 10th level, 15th level, and 20th level.
