Amazonian Steel

Amazonian Steel is a very powerful metal wielded by the Greek Goddess Athena, the Amazons and other inhabitants of Lake Tritonis, as well as select few of the demigod children of Athena.

Characteristics
Amazonian Steel is an extremely rare metal ore that is mined by Cyclopes in the Amazon. It is shaped by being superheated in Mount Etna, or the forges of Lake Tritonis. It then has to be cooled in the deepest extents of the Amazonian river. The metal is lethal to mortals, demigods, monsters and giants alike, but can only cause extreme agony to immortal beings. It is famed for being completely immune to extreme heat, electricity and, once cooled, is pretty much indestructible. It is also unaffected by rust, dirt, acids and bloodstains, meaning that it remains completely clean throughout its use.
