As you journey through the Main Quest,
you will be able to use unwanted weapons to increase the power of your favorites.
This is the power of Weapon Enhancement.
Yoshitsune is a skilled smith, and capable of strengthening your weapons.

Weapons with higher Attack powers
will serve you better than a weak one in battle,
so always prepare to be at full strength.

The rarer and more powerful the weapons you use
as materials, the more effect they
have on enhancing your weapon.
