Starting at 3rd level, you can use your action to unleash both the divine and infernal energy within yourself, causing your body to be enveloped in bright, burning light. The instant you transform, other creatures within 10 feet of you that can see you must each succeed on a Constitution saving throw (DC 8 + your proficiency bonus + your Charisma modifier) or become blinded until the end of your next turn. Once this effect resolves, the light fades to reveal either radiant horns or a burning halo hovering above your head (player's choice).

Your transformation lasts for 1 minute or until you end it as a bonus action. During it, 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 radiant damage equals your level. Additionally, if a creature hits you with a melee weapon or spell attack, you can use your reaction to automatically deal fire damage to the attacking creature. The fire damage equals your level.

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