Uriels Frozen Crown

You create six small shards of ice in your space. They float in the air and orbit your head 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 shards, sending them streaking toward a target you choose within 120 feet of you. On a successful ranged magic attack you do 1d6 + your Spell Modifier piercing damage and 1d6 cold damage and the targets Movement is reduced by 5.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the cold damage increases by 1d6.
