Darksteel, also known as Dunchalcor, was an alloy of arkaan and iron created by Dwarves. Considered to the third strongest metal after adamantine and giranium,
It had the unique power to absorb all magical and mundane electrical energy, including lightning, without transferring a charge or effect to its bearer, without even needing to be in contact with the energy. Unlike kyanium, this did not extent to heat, magic missiles, or forms of pure energy.
Darksteel items were resistant to damage of all kinds, being unaffected by dropping and by natural flames, cold, or electricity, resistant to acid, magical fire, crushing, and even disintegration, and highly resistant to lightning.
Darksteel had a silvery hue when it was cut or polished, while its exposed surfaces bore a deep purple gleaming luster. Almost as hard as adamantine or giranium and nigh-unbreakable, darksteel has the same weight and durability as steel.
