Crown of Ice

Damage: 2d6 cold damage + 2d4 necrotic damage 

As  action you summon a crown of pure white ice. Six snow balls form and Flote around your head. 

You create six tiny snowballs around your head. They float in the air and orbit you for the spell’s duration. When you cast the spell — and as a bonus action on each of your turns thereafter — you can expend one or two of the snowballs, sending them streaking toward a point or points you choose within 120 feet of you. Once a snowball reaches its destination or impacts against a solid surface, the snowball explodes. Each creature within 5 feet of the point where the snowball explodes must make a Dexterity saving throw. A creature takes 3d6 cold and 2d4 narcotic damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the number of snowballs  created increases by two for each slot level above 3rd.
