I remember a spell in AD&D called "fool´s gold". I have not found this spell in the Core rule books. Does this spell still exists, perhaps in some other WotC books or must I convert this spell for D&D 3.X ?
I do not recall seeing it in a WotC product, but there are two versions (or at least spells that do about the same thing) in Bastion Press' Faeries book (a 3.0 book).
