Adamantium
Black and non-metallic, Adamantium is the hardest known substance on Mundus. Adamantium seems to drink in the light, and is non-reactive to both fire and acid. Adamantium is highly prized for it’s lightness and durability, and can only be worked by Artificers.
Weapons made of Adamantium cause Critical Hits on a roll of 19 or 20.
Armor made of Adamantium is half the weight, and the wearer is immune to Critical Hits.
Adamantium bullets do not have their damage reduced by armor.
