Winter Bolt

You create a bolt of pure cold that streaks toward a creature that you can see within range. It must make a constitution saving throw. If it fails, it takes 3d10 cold damage and has disadvantage on dexterity saves and ability checks until the end of their next turn. On a successful save, it takes half damage.

At higher levels When you cast this spell using a spell slot of 3rd level or higher, it does an additional 1d10 damage for every spell level above 2nd.
