Celestial Revelation. When you reach 3rd level, choose one of the revelation options below. Thereafter, you can use a bonus action to unleash the celestial energy within yourself, gaining the benefits of that revelation. Your transformation lasts for 1 minute or until you end it as a bonus action. Once you transform using your revelation below, you can’t use it again until you finish a long rest:

Radiant Consumption. Searing light temporarily radiates from your eyes and mouth. For the duration, you shed bright light in a 10-foot radius and dim light for an additional 10 feet, and at the end of each of your turns, each creature within 10 feet of you takes radiant damage equal to your proficiency bonus. Until the transformation ends, once on each of your turns, you can deal extra radiant damage to one target when you deal damage to it with an attack or a spell. The extra damage equals your proficiency bonus.
