The secret of createing copper automatons is known only to a few, and they are reluctant to share their knowledge. It requires a mage of at least 9th-level and a minimum of 10,000 gp to create a copper automaton. The whole process takes at least two months and involves the use of magma, copper ore, iron gears, and lead counterweights, and at least a single diamond as the source of the copper automaton's magical heat channels. In addition to its purely physical framework, magical ingredients are required to weave the needed enchantments around the physical chassis. These additional requirements include oil of slipperiness (for the gears) and the blood of a salamander or fire snake--even when they are available, the price of these ingredients varies from dear to exorbitant, and this expense may double the cost of an automaton for a mage unable to produce or obtain the ingredients himself.
