Level: illusionist (2nd); mage (2nd)
Creates the illusion that any existing metal will have the appearance of real gold, though no alteration is made to the physical shape of the metal. Wrought iron or lead would appear to be wrought gold, powdered metal would appear to be powdered gold, copper coins would appear to be gold coins and so on.
Because the shape remains the same, however, a copper coin made to appear gold would still have the recognizeable mint stamp of a copper coin, giving reason for the observer to doubt. However, the weight of the coin would seem to be the density of gold. This means that a pound of iron would create the illusion of 2.46 lbs. of gold, while a pound of lead would only create the illusion of 1.7 lbs. of gold, when the specific density of the originating metal is taken into account.
Naturally, any good assayer has the potential of recognizing the dweomer, and for this reason it is always a danger to foist the illusion upon any expert person. As well, it would be rare to receive the full value of the illusionary metal affected. As a bartering tool, however, the spell may be employed to great effect, particularly in any obscure backwater, where the residents might be more gullible and less able to pursue the matter later when the spell's effect wears off.
There is no saving throw associated with the dweomer; but the DM is encouraged to consider the worldiness of the mark, the place and whether the character's efforts to make the presence of the faux-gold, and their willingness to trade it, are believable.
