Throwing Star

You channel the power of starlight and turn it into a throwing knife and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 piercing damage. Hit or miss, the knife then illuminates. The target and each creature within 5 feet of it must succeed on a DEX saving throw or take 1d6 radiant damage and suffer from the blinded condition until the end of your next turn.

At higher levels: For every level it ads 1d6 of radiant damage. So for 2nd level (2d6), 3rd level (3d6) and so on.
