A creature you try to touch is lit in a white flaming burst. Make a melee spell attack against the target. On a hit, the target takes 1d4 radiant damage and must succeed a CON savingthrow or become blinded until the end of its next turn.

The spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
