Waxwood is a rare kind of wood that exists in RuneScape. It was first referenced to in A Void Dance whereupon it is found in Karamja while investigating an escaped pest. The player claims that they have never come across it before, and Jessika notes that it is "ugly and un-treatable", and is not widely used as a material for making anything, though it is naturally waterproof, hence its name, and is often used to seal things in water-tight containers.
