The majority of weapons and items in most Fire Emblem games are characterized by their Usage (called WHp in TearRing Saga: Utna Heroes Saga and known by fans as Weapon Durability), a preset number of uses that determines the maximum amount of times that a weapon or item is functional before it breaks, thus requiring a replacement. Unlike other RPGs, weapons can only be swung about so many times before they are considered unusable. While there are some notable exceptions, such as the Ragnell, Amiti, and several others, most weapons acquired have around 20-45 uses before they wear out and disappear from a character's inventory. A strategical aspect of playing the games is knowing how to kill enemies with as few attacks as possible in order to save the uses of weapons; money may be very limit
