The condition is a property of various items which tells how much the item has been used. Durability tells how much more the item can be used before it will break permanently; it will no longer be usable by the player. A player or Non-player character with the correct skill will be able to repair an item, improving its condition or durability. When an item such as a weapon becomes worn, its performance will generally decrease proportionally. When the green bar of an item such as painkillers is gone completely, the item is considered empty. The item's condition is portrayed by the length of the green bar underneath an item.
