Adamantine

Adamantine is a jet-black alloy of Adamant and other metals. Usually black in colour, Adamantine will have a green sheen when viewed by candlelight or a purple-white sheen when viewed by magical light.

Only found in veins of ore near Earth Nodes and areas of Faerzress in the Underdark. Occasionally small meteorites consisting of some adamantine will fall to Abeir-Toril as well.

Adamantine, when smelted is ultrahard but it is a costly procedure. Adamantine weapons are useful for damaging the weapons and armour of your opponents. A set of adamantine armour or a shield is nearly impenetrable to normal weapons.

Adamantine is used often by Drow elves of the Underdark, and their adamantine weapons are usually swords that are magically blessed. Their magical strength and sharpness fade if brought into contact with direct sunlight.
