Adamantine

Adamantine is an incredibly rare metal, 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.
