The items created in the creation kiln depend on the class of clay carried by the player using it. For example, with class 3 clay players can make class 3 items, and with class 5 clay players could make class 5 items. The only exceptions are runes and Clay deposit scrolls. They have no class, but the quantity created depend on the quality of the clay. 15 elemental runes, Catalytic runes or 1 clay deposit scroll could be made from one piece of class 1 clay, 30 runes and 2 scrolls from class 2 clay, 45 runes and 3 scrolls from class 3, and so on.
