Indestructible is an item modifier that removes durability from an item, such that it can never be broken. In Diablo I, this was accomplished with the suffix of the Ages. In Diablo II, this was shortened to just of Ages. A socketed item can also have a Zod Rune inserted, which makes it indestructible. This is generally only a minor advantage, unless an Ethereal Item is used. Due to the fact that ethereal items are stronger than non-ethereal items of the same type, but cannot be repaired, being indestructible is a very useful advantage.
