Imperial Gold

Imperial Gold is a metal that can destroy monsters. It is made by consecrating it in the Temple of Jupiter on Capitoline Hill in Rome. The metal is extremely rare, but very powerful. It seems to be the Roman version of Celestial bronze. Like the Roman emperors, it is quite volatile, as stated by Medea. It explodes in a ring of force when broken, as shown when Jason's lance broke when he fought Enceladus, but this blast is not lethal to stronger monsters. Imperial Gold may be slightly harder and stronger than Celestial bronze and because they are forged from the Temple of Jupiter, they can be used to harm storm spirits. Like how the Greek warriors usually used Celestial bronze, this is supposedly the most common weapon used by Roman heroes.
