Goldsmith
Compared to other metals, gold is malleable, ductile, rare, and it is the only solid metallic element with a yellow color. It may easily be melted, fused, and cast without the problems of oxides and gas that are problematic with other metals such as bronzes, for example. It is fairly easy to "pressure weld", wherein similarly to clay two small pieces may be pounded together to make one larger piece. Gold is classified as a noble metal—because it does not react with most elements. It usually is found in its native form, lasting indefinitely without oxidization and tarnishing.
Metallic dragon
While bronze dragons are often fascinated with battles, especially fighting to defeat evil, they have strong moral compunctions against killing living beings unless absolutely necessary. They will often join good-aligned armies to fight the forces of evil, either in human form or their own. In battle, their weapon of choice is to breathe repulsion gas, which is so putrid that it forces absolutely everything away. They also like to relocate a foe to a remote location where it can do no harm when possible. When forced to kill, the bronze dragon is a deadly combatant, roasting enemies with bursts of lightning or ripping them open with its clawed forelegs.Copper dragons are the second weakest of the metallic dragons. They are born tricksters and jokesters. They are quite devious and clever, but their intent is purely benign. They do not seek to harm 'lesser' creatures, but merely wish to impress them with superior intelligence and wit, and to fool them with clever pranks.
