Clay is an item that is always in demand due to soft clay being used in Crafting. There are many locations to mine clay, but one of the best locations is in the Burthorpe mines, located southwest of the bank. Players should mine in the northern most cavern where there are two clay rocks located by each other. Clay rocks respawn at a very high rate regardless of the server population, though having two rocks to yourself will greatly decrease the time required to fill your inventory. Once you have a full inventory, leave the mines and deposit your clay at the bank.
