Limestone bricks can also be bought from Mort'ton building store for a price of 10 coins; however, it is required that a player completes the Shades of Mort'ton quest first.
Players can also mine their own limestone west of Paterdomus (east of Varrock) or Arandar and use a chisel to make it into limestone bricks.
