Alchemist’s Frost

This sticky, adhesive fluid, draws heat from the surrounding area when exposed to air. As an action, you can throw this flask up to 20 feet, shattering it on impact. Make a ranged attack against a creature or object, treating the alchemist’s frost as an improvised weapon. On a hit, the target takes 1d4 cold damage at the start of each of its turns. A creature can end this damage by using its action to make a DC 10 Dexterity check to scrape off the fluid.

Notes: Damage: Cold, Damage, Container
