Liquid Ice

Also known as “alchemist's ice,” this sealed jar of crystalline blue fluid immediately starts to evaporate once opened. During the next 1d6 rounds, you can use it to freeze a liquid or to coat an object in a thin layer of ice. You can also throw liquid ice as a splash weapon. A direct hit deals 1d6 points of cold damage; creatures within 5 feet of where it hits take 1 point of cold damage from the splash.
