Arctic Arrow

You make a ranged attack with the weapon used in the spell’s casting against a creature you can see within the weapon’s range. In place of ammunition, you fire a mote of pure frost. On a hit, the target suffers the weapon attack’s normal effects, and it is sheathed in ice until the end of your next turn. If the creature suffers bludgeoning, piercing, or slashing damage before the spell ends, the ice shatters, dealing it 1d4 cold damage. The spell then ends.

At Higher Levels. At 5th-level, the initial attack deals an extra 1d8 cold damage on a hit, and the damage dealt if the ice is shattered increases to 2d4. Both damage rolls increase at 11th-level (2d8 and 3d4), and again at 17th-level (3d8 and 4d4).
