Dark Darts

Pitch black darts are thrown from your hands.  They fill the user with a cold sense of terror.

Make a ranged spell attack.  On a hit they deal 1d6 cold damage, the creature has disadvantage on it's next saving throw.

At higher levels you cast additional darts: 5th level (2), 11th level (3), 17th level (4).  You must make additional attack rolls for each added dart and may choose new targets for each within range.
