Adventurer's Talent: Cleric

You've gained the ability to channel divine energy directly from the gods, emboldening your allies and sanctifying their attacks. As a bonus action, you choose a creature within 30 feet. The chosen creature gains temporary hit points equal to your Charisma modifier + half your level in this class for 10 minutes. While a creature has temporary hit points granted by this spell, they can choose to lose these temporary hit points when they hit a creature with an attack, dealing additional radiant damage equal to the temporary hit points they lost. Once you use this talent, you must finish a short or long rest before you can use it again.
