Radiant energy glows in your hand as you reach out and try to touch a creature within range. Make a melee spell attack against the target. On a hit, the target takes 1d8 radiant damage, and it emits bright light in a 5-foot radius, and dim light for an additional 5-feet until the end of your next turn.

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
