Ice coolers are boxes filled with very cold water. They are used to kill desert lizards as the final blow. You must use the ice cooler on the lizard when it has 1-4 Hitpoints left, or else you'll end up wasting the cooler. They can be bought from any Slayer master.

Only one ice cooler can be used per desert lizards, so be sure to bring at least the amount of ice coolers as the number of lizards you have to kill. More are recommended due to the possibility of wasting coolers.
