This is much less pure alloy of normal Adamantium. While it is not as strong as its parent metal, it has the advantage of not dissolving in sunlight (if used by Drow). It is most commonly used by raiding parties from the Underdark in cases where the risk of people and equipment being captured is high.

Items made of Low-grade Adamantium weigh the same as their steel counterparts and cost 150x more than normal. Weapons gain a +1 to hit and +1d2 MORE damage; Armor gains a +1 bonus. Items count as +1 magical weapons and gain a +1 to all saving throws.
