Frigid Azote (Flask)

When you take the Attack action, you can replace one of your attacks with throwing a flask of Frigid Azote. Target one creature or object you can see within 20 feet of yourself. The target must succeed on a Dexterity saving throw (DC 8 plus your Dexterity modifier and Proficiency Bonus) or take 2d6 Cold damage and its speed is halved until the end of its next turn.
