Even the greatest weapons need some maintenance every now and then or they become not that great when their blades can't cut through anything anymore. Having your equipment in top notch shape all the time can be a big bonus in combat. Still, keeping your weapon maintained will not make you a great hero if you don't know how to use it properly.
