Stronger weapons
This only works in normal and Hard mode. As soon as you access the stage "The Tower of Lezard Valeth" You will be able to find the creation jewel. When eqquiped on Valkyrie, the broken weapons and armor can now be transmuted into the powerful Glance weapons and armor. Top notch gear until you hit Seraphic Gate. It will also make the tome of Everlasting life into an ice sword, capable of obliterating all fire based opponents in one hit.
