Alchemist’s Frost

This ceramic flask explodes in an icy haze when it hits, crippling its target with numbing cold.

As an action, you can throw the vial up to 20 feet, shattering it on impact. Make a ranged attack against a creature or object, treating the vial as an improvised weapon. On a hit, the attack deals 1d10 cold damage; on miss, the target takes half damage.
