Chill Arrow

The next time you hit with a ranged weapon attack that uses ammunition before the spell ends, the target takes cold damage equal to your spellcasting ability modifier.

At Higher Levels: When you reach level 5, the damage increases to 1d6 + your spellcasting ability modifier, 2d6 + your spellcasting ability at level 11, and 3d6 + your spellcasting ability at level 17.
