Blue Light

You conjure a floating bluish silver light the size of a grapefruit.  For the duration, the light floats beside you, shedding bright light out 20 feet and dim light for an additional 20 feet.

At any time during the duration, you can use your bonus action to throw the light up to 90 feet.  Make a ranged spell attack.  If you hit, the target suffers 1d6+1 damage and is slowed by 50% until the start of your next turn.

the damage of Blue Light scales by an additional 1d6+1 at levels 5, 11, and 17.
