"Well, it's nothing too hard to understand," said Durgrim, pointing his index at the armor. "The tier is obviously related to the material, while the rank has to do with the craftsman and enchanter's proficiency."

But the most important part is the intricate engravings hidden in the interior. They allow the base materials to absorb more pressure without breaking, meaning the end product can carry more potent or a higher number of enchantments."
