Adamantine

Adamantine was a jet-black alloy of adamant and other metals. Usually black in color, adamantine had a green sheen when viewed by candlelight or a purple-white sheen when viewed by magical light.

Applications
Adamantine, when smelted, was ultra-hard but this was a costly procedure. Adamantine weapons made with the most common formulation around were useful for damaging the weapons and armor of opponents clad in just about any other material, while a set of adamantine armor absorbed a significant amount of energy from most physical blows. More importantly, many creatures, such as for instance golems, were very difficult to damage effectively with a weapon not made of adamantine.

Adamantite was often used by drow elves of the Underdark, and their adamantite weapons were usually swords that were magically enhanced. Their magical strength and sharpness faded if brought into contact with direct sunlight. Adamantite was also preferred as an alloy component for magical armor of superior enchantment.

Production
Its main component was either pure adamant, or a mixed ferrous ore known as adamantite, found only in veins of ore in volcanic zones, near earth nodes, and areas of faerzress in the Underdark. Occasionally, small meteorites consisting of some adamantite would fall to Abeir-Toril as well. It could also be found in earthmotes.

Per primary sources, adamantine was produced out of alloying its ores with mithral Adamantine was extremely difficult to produce, requiring high forging temperatures and a very delicate procedure. Per other sources, it was composed of five parts adamant, two parts silver, and one part electrum. Most smiths that specialized in producing adamantine were dwarves, particularly those from the ancient kingdom of Ammarindar. Those same sources also asserted it was possible to produce adamantine as an alloy of mithral and steel through the application of several magical procedures, although the process to do so was exceedingly complex. Dwarves considered that a joke at the expense of foolish bards. By, electrum alloys had fallen out of favor, and only high-purity alloys circulated, favored for their ability to break most other metals.

The githzerai used their knowledge of Limbo to bring a shard of it when they traveled to the Prime Material plane. A group of anarchs then molded that essence of Limbo into large adamantine citadels that served as remote bases from which to observe enemies or to launch attacks.

Users of arcane magic who had surpassed the limits of what was known to be possible could synthesize adamantine in incredible quantities by using a wish to transmute steel. This was a necessity when creating an adamantine golem, though this was beyond the normal constraints of the spell. Sages such as Elminster attested to other processes that created adamantine out of mithral and steel, but those processes were likely not metallurgical in nature, as the mention of them elicited little but laughter out of dwarves.

Costs
After the Spellplague, a set of adamantine manacles was worth about 650 gp. Before, a good set of adamantine shackles cost 400 gp. After the Second Sundering, a 10-pound adamantine bar could be had in Waterdeep for the low, low price of 1,000 gp.
