-In NetHack 3.0.0, metal objects have a boolean determining if they are subject to erosion or not, which consists of their [[enchantment]] being lowered rather than the item itself being damaged. Objects made of a material that does not fit into these broad categories, such as the [[bullwhip]] and [[leather armor]], are treated as "undefined". Versions following NetHack 3.0.0 gradually add other materials and differentiate them further from each other (e.g. copper, mithril and silver), with much of the current material list established by the last release of the 3.0 series in [[NetHack 3.0.10]]: the material list is composted of glass, wood, copper, metal, silver, gold, platinum, mineral, and mithril.

+Versions following NetHack 3.0.0 gradually differentiate materials further from each other, with [[NetHack 3.1.0]] establishing much of the current material list by adding material types such as bone, leather, gemstone, iron, and dragon hide while also introducing the current erosion system.
