While weapons are used to inflict death upon one's foe, the very weapon
itself may be subject to harm. Only the most durable, and usually
magically enchanted, weapons are unbreakable, and this quality of weapon
is very rare indeed. Most weapons if not used properly, or through some
freak accident, may fail during battle. Weapons may splinter, crack, or
even shatter under the extreme rigors of combat. Magical spells may offer
some protection giving the wielder of that weapon a little more peace of
mind, knowing that he is less likely to find himself without his trusty
sword, when the time comes where he needs it most.
