Dazzling Moonlight

A 20-foot-radius sphere of light spreads out from a point you choose within range. The sphere is illuminated by a searing bright silvery light takes 3d6 radiant damage and must succeed a Dexterity saving throw or become stunned until the end of your next turn. Every creature less than 5 feat outside the sphere also makes a Dexterity saving throw. On a fail the creature is blinded until the end of it next turn and takes 1d6 radiant damage but the creature is unaffected on a success. 

If any of this spell's area overlaps with an area of darkness created by a spell of 3rd level or lower, the spell that created the darkness is dispelled.
