Light rays swirl around you, manifesting as a radiant aura that covers you and your gear. You gain 5 temporary hit points for the duration. If a creature hits you with a melee attack while you have these hit points, the creature takes 5 radiant damage. In addition you shed bright light up to 30 feet and dim light up to 60 feet. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, both temporary hit points and radiant damage increase by 5 for each slot.
