''For a description of material script code, see [[Materials (detailed)]].'' ''For a quick reference sheet of all materials see [[List of Material Values]].'' Every [[Items|item]] in the game has a material type. The type of material affects the items's statistics, mainly its sturdiness, weight and cost, plus damage done by using the item as [[weapon]]. This is a general purpose reference list for materials in IVAN. If you are looking for details on what each material's script properties mean, please see [[Materials (detailed)]].
Most items except for some [[:Category:Artifacts|artifact]]s may have their material changed by [[scrolls]] of harden material or change material. The way materials harden can be seen in the table below, while changing the material of an item prompts you to select any material you would like. However, you need to have a certain amount of [[intelligence]] to successfully transmute an item, seen in the "Int" column of the table. If your intelligence in insufficient, you will be promted to either select other item to harden with a scroll of harden material, or to select different material for a scroll of change material. Also note that you need to have more intelligence in order to change the material directly than only to harden it. For example, it takes 25 Int to harden [[Arcanite]] to [[Mithril]], but to change a different material directly into mithril, it takes 30 Int.
