The main difference between making a Low-Level and a High-Level Equipment was the amount of Spiritual Energy used. The procedures were basically the same. Of course, due to the materials' toughness and elasticity, different timings and temperatures were necessary.
That being said, Rean took a lot longer to figure out the best combinations. Other than going back to sleep and the morning training of the Iron and Blood District/Facion, Rean spent most of his time in the Blacksmith Hall.
During the years that he and Roan used the Light Sab-cough, cough... Spiritual Kaz Swords, Rean noticed a big difference. His Sword was much better on Roan's hands than his own. However, it had nothing to do with higher proficiency in weapons or combat. That difference was in the elements that they control.
