Circle of Ice

You speak the arcane words and throw 4 shards of ice in the air. As the ice shards begin to hover behind you, you can take an action to do one of these things:

• You can shoot one ice shard at an enemy within range. Make a ranged spell attack, on a hit the target takes 3d8 cold damage.
• You can hurl one ice shard on the ground within range. Each creature within 10 feet of the impact must make a Dexterity saving throw or take 2d8 cold damage, or half as much on a success. The area is now considered difficult terrain.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the cold damage increases by 1d8 for each slot level above 3rd.
