How about these:
 * Non-magnetic metals are harder to reforge.
 * Can't reforge one metal into two metals.
 * Stronger metals takes time (10-15 seconds) to reforge.
 * May be unable to reforge sodium, copper, aluminum, zinc, magnesium and mercury. Being limited to reforging only from already existing sources.
