Most armour sets in the mod give the protection of iron 15 (). However, some sets of armour provide additional protection. This is usually 17 (), although mithril is an exception, providing 20 (), as much as diamond armour. However, following the addition of the Modifier system, it is possible to get iron-tier armour to the same level of protection as Mithril, however it cannot exceed 80% protection. It is for this reason that mithril cannot receive protection increase modifiers.
